Port the project from autotools to meson. All build options are
preserved with the same semantics.
The goal of this change is to produce the same set of files as the
current autotools approach: libraries with correct SONAME/version,
headers, pkg-config files, GObject introspection data, Python extension
modules, D-Bus interface and configuration files. This is done to enable
a one-liner test command running all available test suites.
The only thing we drop is the `make docs` target as it's rarely used and
docs can be generated easily with sphinx directly. They are also not
required for testing.
The Rust workspace is built via a custom target that invokes cargo and
uses SYSTEM_DEPS_* environment variables to point the libgpiod-sys and
gpiosim-sys crates at the locally built C libraries.
In addition to porting the build files to meson, update the docs, remove
unneded items from .gitignore files (or remove them entirely if they're
no longer needed) and update the shunit2 test scripts to no longer care
about source directories.

Simplify the find_line_by_name example by using
gpiod_chip_get_line_offset_from_name() rather than iterating over each
line in a chip.

For any given target (let's say foobar), automake defaults to looking for
foobar.c if foobar_SOURCES are not specified. Remove redundant assignments
as we've seen multiple hidden typos in makefiles already.

The watch_line_info example prints the u64 timestamps using "%ld" which
produces a warning for 32bit. Replace it with PRIu64.

Some of the file comments are cut-and-paste errors, so replace them
with the correct comment.

A collection of minor cleanups to make the examples more consistent and
ease the addition of more examples:
- reformat Makefile.am to simplify adding more examples
- add line offset to value output
- remove commas from edge event output
- replace while(1) with for (;;)
- fix a typo in Makefile.am
- fix an error handling goto in toggle_line_value.c

The tools have served as example code, but have become too complicated
to serve that purpose.
Add a set of examples that have no purpose other than providing minimal
examples of common use cases.
