We've had a mixture of the warnings pragma, the -w switch on the shebang
line, and no warnings at all. This patch removes the -w swicth and add
the warnings pragma to all perl sources missing it. It raises the
severity of the TestingAndDebugging::RequireUseWarnings perlcritic
policy to level 5, so that we catch any future violations.

headerscheck and cpluspluscheck should skip the recently-added
cmdtaglist.h header, since (like kwlist.h and some other similarly-
designed headers) it's not meant to be included standalone.
evtcache.h was missing an #include to support its usage of Bitmapset.
typecmds.h was missing an #include to support its usage of ParseState.
The first two of these were evidently oversights in commit 2f9661311.
I didn't track down exactly which change broke typecmds.h, but it
must have been some rearrangement in one of its existing inclusions,
because it's referenced ParseState for quite a long time and there
were not complaints from these checking programs before.
src/include/common/unicode_combining_table.h is currently not meant to
be included standalone. Things could be refactored to allow it, but
that would be beyond the present purpose. So adding an exclusion here
seems best.

We already had "cpluspluscheck", which served the dual purposes of
verifying that headers compile standalone and that they compile as C++.
However, C++ compilers don't have the exact same set of error conditions
as C compilers, so this doesn't really prove that a header will compile
standalone as C.
Hence, add a second script that's largely similar but runs the C
compiler not C++.
Also add a bit more documentation than the none-at-all we had before.

Teach it to scrape -I and -D switches from CPPFLAGS in Makefile.global.
This is useful for testing on, eg, FreeBSD, where you won't get far
without "-I/usr/local/include".
Also, expand the set of blacklisted-for-unportability atomics headers,
based on noting that arch-x86.h fails to compile on an ARM box. The
other ones I'd omitted seem to compile all right on architectures they
don't belong to, but that's surely too shaky to rely on. Let's do
like we did for the src/include/port/ headers, and ignore all except
the variant that's pulled in by the arch-independent header.
Declaring a function "inline" still doesn't work with Windows compilers
(C99? what's that?), unless the macro provided by pg_config.h is
in-scope, which it is not in our ECPG test programs. So the workaround
I tried to use in commit 7640f9312 doesn't work for Windows. Revert
the change in printf_hack.h, and instead just blacklist that file
in cpluspluscheck --- since it's a not-installed test file, we don't
really need to verify its C++ cleanliness anyway.
Formerly, cpluspluscheck was only meant to examine headers that
we thought of as exported --- but its notion of what we export
was well behind the times. Let's just make it check *all* .h
files, except for a well-defined blacklist, instead.
While at it, improve its ability to use a C++ compiler other than g++,
by scraping the CXX setting from Makefile.global and making it possible
to override the warning options used (per suggestion from Andres Freund).

This complies with the perlcritic policy
Subroutines::RequireFinalReturn, which is a severity 4 policy. Since we
only currently check at severity level 5, the policy is raised to that
level until we move to level 4 or lower, so that any new infringements
will be caught.
A small cosmetic piece of tidying of the pgperlcritic script is
included.

Fix all perlcritic warnings of severity level 5, except in
src/backend/utils/Gen_dummy_probes.pl, which is automatically generated.

Avoid compile problems with defines being redefined after the removal of
the #if blocks.
Change script to use shell functions for simplicity.
This is slower than the original coding but avoids the problem of
including files in an unpredictable order. Aside from being more
trustworthy, we can get rid of some exclusions that were formerly
made for what turn out to be ordering or re-inclusion problems.
I also modified it to include libpq's exported files in the check.
ecpg should be included as well, but I'm unclear on which ecpg .h
files are meant to be included by clients.
