SPI_connect/SPI_connect_ext have not returned any value other than
SPI_OK_CONNECT since commit 1833f1a1c in v10; any errors are thrown
via ereport. (The most likely failure is out-of-memory, which has
always been thrown that way, so callers had better be prepared for
such errors.) This makes it somewhat pointless to check these
functions' result, and some callers within our code haven't been
bothering; indeed, the only usage example within spi.sgml doesn't
bother. So it's likely that the omission has propagated into
extensions too.
Hence, let's standardize on not checking, and document the return
value as historical, while not actually changing these functions'
behavior. (The original proposal was to change their return type
to "void", but that would needlessly break extensions that are
conforming to the old practice.) This saves a small amount of
boilerplate code in a lot of places.

Previously, meson installed modules under src/test/modules/ as part of
a normal installation, even though these files are only meant for use
by tests. This is because there is no way to set up up the build
system to install extra things only when told.
This patch fixes that with a workaround: We don't install these
modules as part of meson install, but we create a new "test" that runs
before the real tests whose action it is to install these files. The
installation is done by manual copies using a small helper script.

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.

PL/Sample is an example template of procedural-language handler. This
can be used as a base to implement a custom PL, or as a facility to test
APIs dedicated to PLs. Much more could be done in this module, like
adding a simple validator, but this is left as future work.
The documentation included originally some C code to understand the
basics of PL handler implementation, but it was outdated, and not really
helpful either if trying to implement a new procedural language,
particularly when it came to the integration of a PL installation with
CREATE EXTENSION.
