This commit reshapes the grammar of some commands to apply a more
consistent style across the board, following rules similar to
ce1b0f9da0:
- Elimination of some pointless used-once variables.
- Use of long options, to self-document better the options used.
- Use of fat commas to link option names and their assigned values,
including redirections, so as perltidy can be tricked to put them
together.

Files in common/ and fe_utils/ that contain translatable strings need
to be listed in the nls.mk files of the programs that use them. (Not
great, but that's the way it works for now.) This usually requires
some manual analysis which is done about once during each major
release beta period. This time, I wrote a hackish script that figures
some of this out more automatically, so this update is a bit larger as
it also includes some files that were missed in the past.
This checks that certain I/O-related Perl functions properly check
their return value. Some parts of the PostgreSQL code had been a bit
sloppy about that. The new perlcritic warnings are fixed here. I
didn't design any beautiful error messages, mostly just used "or die
$!", which mostly matches existing code, and also this is
developer-level code, so having the system error plus source code
reference should be ok.
Initially, we only activate this check for a subset of what the
perlcritic check would warn about. The effective list is
chmod flock open read rename seek symlink system
The initial set of functions is picked because most existing code
already checked the return value of those, so any omissions are
probably unintended, or because it seems important for test
correctness.
The actual perlcritic configuration is written as an exclude list.
That seems better so that we are clear on what we are currently not
checking. Maybe future patches want to investigate checking some of
the other functions. (In principle, we might eventually want to check
all of them, but since this is test and build support code, not
production code, there are probably some reasonable compromises to be
made.)

There are a lot of Perl scripts in the tree, mostly code generation
and TAP tests. Occasionally, these scripts produce warnings. These
are probably always mistakes on the developer side (true positives).
Typical examples are warnings from genbki.pl or related when you make
a mess in the catalog files during development, or warnings from tests
when they massage a config file that looks different on different
hosts, or mistakes during merges (e.g., duplicate subroutine
definitions), or just mistakes that weren't noticed because there is a
lot of output in a verbose build.
This changes all warnings into fatal errors, by replacing
use warnings;
by
use warnings FATAL => 'all';
in all Perl files.

A PostgreSQL release tarball contains a number of prebuilt files, in
particular files produced by bison, flex, perl, and well as html and
man documentation. We have done this consistent with established
practice at the time to not require these tools for building from a
tarball. Some of these tools were hard to get, or get the right
version of, from time to time, and shipping the prebuilt output was a
convenience to users.
Now this has at least two problems:
One, we have to make the build system(s) work in two modes: Building
from a git checkout and building from a tarball. This is pretty
complicated, but it works so far for autoconf/make. It does not
currently work for meson; you can currently only build with meson from
a git checkout. Making meson builds work from a tarball seems very
difficult or impossible. One particular problem is that since meson
requires a separate build directory, we cannot make the build update
files like gram.h in the source tree. So if you were to build from a
tarball and update gram.y, you will have a gram.h in the source tree
and one in the build tree, but the way things work is that the
compiler will always use the one in the source tree. So you cannot,
for example, make any gram.y changes when building from a tarball.
This seems impossible to fix in a non-horrible way.
Second, there is increased interest nowadays in precisely tracking the
origin of software. We can reasonably track contributions into the
git tree, and users can reasonably track the path from a tarball to
packages and downloads and installs. But what happens between the git
tree and the tarball is obscure and in some cases non-reproducible.
The solution for both of these issues is to get rid of the step that
adds prebuilt files to the tarball. The tarball now only contains
what is in the git tree (*). Getting the additional build
dependencies is no longer a problem nowadays, and the complications to
keep these dual build modes working are significant. And of course we
want to get the meson build system working universally.
This commit removes the make distprep target altogether. The make
dist target continues to do its job, it just doesn't call distprep
anymore.
(*) - The tarball also contains the INSTALL file that is built at make
dist time, but not by distprep. This is unchanged for now.
The make maintainer-clean target, whose job it is to remove the
prebuilt files in addition to what make distclean does, is now just an
alias to make distprep. (In practice, it is probably obsolete given
that git clean is available.)
The following programs are now hard build requirements in configure
(they were already required by meson.build):
- bison
- flex
- perl

By default, pg_archivecleanup does not remove backup history files.
These are just few bytes useful for debugging purposes, still keeping
them around can bloat an archive path history files mixed with the WAL
segments if the path has a long history.
This patch adds a new option to control if backup history files are
removed, depending on the oldest segment name to keep around.
While on it, the TAP tests are refactored so as these are now able to
handle lists of files. Each file has a flag to track if it should still
exist or not depending on the oldest segment defined with the command
run.

Run pgindent, pgperltidy, and reformat-dat-files.
This set of diffs is a bit larger than typical. We've updated to
pg_bsd_indent 2.1.2, which properly indents variable declarations that
have multi-line initialization expressions (the continuation lines are
now indented one tab stop). We've also updated to perltidy version
20230309 and changed some of its settings, which reduces its desire to
add whitespace to lines to make assignments etc. line up. Going
forward, that should make for fewer random-seeming changes to existing
code.

The generated resource files aren't exactly the same ones as the old
buildsystems generate. Previously "InternalName" and "OriginalFileName" were
mostly wrong / not set (despite being required), but that was hard to fix in
at least the make build. Additionally, the meson build falls back to a
"auto-generated" description when not set, and doesn't set it in a few cases -
unlikely that anybody looks at these descriptions in detail.

Autoconf is showing its age, fewer and fewer contributors know how to wrangle
it. Recursive make has a lot of hard to resolve dependency issues and slow
incremental rebuilds. Our home-grown MSVC build system is hard to maintain for
developers not using Windows and runs tests serially. While these and other
issues could individually be addressed with incremental improvements, together
they seem best addressed by moving to a more modern build system.
After evaluating different build system choices, we chose to use meson, to a
good degree based on the adoption by other open source projects.
We decided that it's more realistic to commit a relatively early version of
the new build system and mature it in tree.
This commit adds an initial version of a meson based build system. It supports
building postgres on at least AIX, FreeBSD, Linux, macOS, NetBSD, OpenBSD,
Solaris and Windows (however only gcc is supported on aix, solaris). For
Windows/MSVC postgres can now be built with ninja (faster, particularly for
incremental builds) and msbuild (supporting the visual studio GUI, but
building slower).
Several aspects (e.g. Windows rc file generation, PGXS compatibility, LLVM
bitcode generation, documentation adjustments) are done in subsequent commits
requiring further review. Other aspects (e.g. not installing test-only
extensions) are not yet addressed.
When building on Windows with msbuild, builds are slower when using a visual
studio version older than 2019, because those versions do not support
MultiToolTask, required by meson for intra-target parallelism.
The plan is to remove the MSVC specific build system in src/tools/msvc soon
after reaching feature parity. However, we're not planning to remove the
autoconf/make build system in the near future. Likely we're going to keep at
least the parts required for PGXS to keep working around until all supported
versions build with meson.

This reverts commit 617d691412.
While I still think the basic idea is attractive, we need to sort
out what happens with built .c files, and there also seem to be
VPATH issues.
The backend already used a mechanically-generated list of *.c files,
but everywhere else we had a manually-written-out list of files in
which to seek translatable messages. Commit b0a55e432 contains the
latest in a long line of failures to update those lists. Rather than
manually fix its oversight, let's change to using "$(wildcard *.c)"
in all these nls.mk files.
Many of these files also have manual references to some *.c files
in other directories, most often src/common/. Perhaps we should try
to improve that situation too; but it's a bit less clear how, so for
now just fix the local file references.

This moves the list of available languages from nls.mk into a separate
file called po/LINGUAS. Advantages:
- It keeps the parts notionally managed by programmers (nls.mk)
separate from the parts notionally managed by translators (LINGUAS).
- It's the standard practice recommended by the Gettext manual
nowadays.
- The Meson build system also supports this layout (and of course
doesn't know anything about our custom nls.mk), so this would enable
sharing the list of languages between the two build systems.
(The MSVC build system currently finds all po files by globbing, so it
is not affected by this change.)

Get rid of the separate "FATAL" log level, as it was applied
so inconsistently as to be meaningless. This mostly involves
s/pg_log_fatal/pg_log_error/g.
Create a macro pg_fatal() to handle the common use-case of
pg_log_error() immediately followed by exit(1). Various
modules had already invented either this or equivalent macros;
standardize on pg_fatal() and apply it where possible.
Invent the ability to add "detail" and "hint" messages to a
frontend message, much as we have long had in the backend.
Except where rewording was needed to convert existing coding
to detail/hint style, I have (mostly) resisted the temptation
to change existing message wording.

Rather than doing manual book keeping to plan the number of tests to run
in each TAP suite, conclude each run with done_testing() summing up the
the number of tests that ran. This removes the need for maintaning and
updating the plan count at the expense of an accurate count of remaining
during the test suite runtime.
This patch has been discussed a number of times, often in the context of
other patches which updates tests, so a larger number of discussions can
be found in the archives.

The five modules in our TAP test framework all had names in the top
level namespace. This is unwise because, even though we're not
exporting them to CPAN, the names can leak, for example if they are
exported by the RPM build process. We therefore move the modules to the
PostgreSQL::Test namespace. In the process PostgresNode is renamed to
Cluster, and TestLib is renamed to Utils. PostgresVersion becomes simply
PostgreSQL::Version, to avoid possible confusion about what it's the
version of.

Incrementing the level of the call stack reported is useful for
debugging purposes as it allows to control which part of the test is
exactly failing, especially if a test is structured with subroutines
that call routines from Test::More.
This adds more incrementations of $Test::Builder::Level where debugging
gets improved (for example it does not make sense for some paths like
pg_rewind where long subroutines are used).
A note is added to src/test/perl/README about that, based on a
suggestion from Andrew Dunstan and a wording coming from both of us.

The following changes are done:
- In pg_archivecleanup, the cleanup of older WAL segments would never
fail immediately.
- In pgbench, the initialization of a thread barrier would not fail
hard.
- In pg_recvlogical, a stat() failure never got the call.
- In pg_basebackup, two chmod() reported a failure without exit()'ing
when unpacking some tar data freshly received. It may be possible to
continue writing some data even after this failure, but that could be
confusing to the user at the end.
These are arguably bugs, but they would happen for code paths where a

Instead of hard-wiring specific verbosity levels into the option
processing of client applications, invent pg_logging_increase_verbosity()
and encourage clients to implement --verbose by calling that. Then,
the common convention that more -v's gets you more verbosity just works.
In particular, this allows resurrection of the debug-grade messages that
have long existed in pg_dump and its siblings. They were unreachable
before this commit due to lack of a way to select PG_LOG_DEBUG logging
level. (It appears that they may have been unreachable for some time
before common/logging.c was introduced, too, so I'm not specifically
blaming cc8d41511 for the oversight. One reason for thinking that is
that it's now apparent that _allocAH()'s message needs a null-pointer
guard. Testing might have failed to reveal that before 96bf88d52.)

When maintaining or merging patches, one of the most common sources
for conflicts are the list of objects in makefiles. Especially when
the split across lines has been changed on both sides, which is
somewhat common due to attempting to stay below 80 columns, those
conflicts are unnecessarily laborious to resolve.
By splitting, and alphabetically sorting, OBJS style lines into one
