No members of the buildfarm are using this version of Visual Studio,
resulting in all the code cleaned up here as being mostly dead, and
VS2017 is the oldest version still supported.
More versions could be cut, but the gain would be minimal, while
removing only VS2013 has the advantage to remove from the core code all
the dependencies on the value defined by _MSC_VER, where compatibility
tweaks have accumulated across the years mostly around locales and
strtof(), so that's a nice isolated cleanup.
Note that this commit additionally allows a revert of 3154e16. The
versions of Visual Studio now supported range from 2015 to 2022.

Documentation and any code paths related to VS are updated to keep the
whole consistent. Similarly to 2017 and 2019, the version of VS and the
version of nmake that we use to determine which code paths to use for
the build are still inconsistent in their own way.
Backpatch down to 10, so as buildfarm members are able to use this new
version of Visual Studio on all the stable branches supported.

Previously the 'includes' field was a string. It's slightly nicer to
manage this when it's defined as an array instead. This allows us to
more easily detect and eliminate duplicates.

It was for unclear reasons defined in a separate location, which makes
it more cumbersome to override for testing, and it also did not have
any prominent documentation. Move to pg_config_manual.h, where
similar things are already collected.
The previous definition on the command-line had the effect of defining
it to the value 1, but now that we don't need that anymore we just
define it to empty, to simplify manual editing a bit.

In 86d78ef50e I enabled configure to check for C99 support, with the
goal of checking which platforms support C99. While there are a few
machines without C99 support among our buildfarm animals,
de-supporting them for v12 was deemed acceptable.
While not tested in aforementioned commit, the biggest increase in
minimum compiler version comes from MSVC, which gained C99 support
fairly late. The subset in MSVC 2013 is sufficient for our needs, at
this point. While that is a significant increase in minimum version,
the existing windows binaries are already built with a new enough
version.
Make configure error out if C99 support could not be detected. For
MSVC builds, increase the minimum version to 2013.
The increase to MSVC 2013 allows us to get rid of VCBuildProject.pm,
as that was only required for MSVC 2005/2008.

This patch does two things. First, it silences a number of compile-time
warnings in the msvc tools files, mainly those due to the fact that in
some cases we have more than one package per file. Second it supplies a
dummy Perl library with just enough of the Windows API referred to in
our code to let it run these checks cleanly, even on Unix machines where
the code is never supposed to run. The dummy library should only be used
for that purpose, as its README notes.
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.

The vertical tightness settings collapse vertical whitespace between
opening and closing brackets (parentheses, square brakets and braces).
This can make data structures in particular harder to read, and is not
very consistent with our style in non-Perl code. This patch restricts
that setting to parentheses only, and reformats all the perl code
accordingly. Not applying this to parentheses has some unfortunate
effects, so the consensus is to keep the setting for parentheses and not
for the others.
The diff for this patch does highlight some places where structures
should have trailing commas. They can be added manually, as there is no
automatic tool to do so.

Notably, this permits linking to the 32-bit Perl binaries advertised on
perl.org, namely Strawberry Perl and ActivePerl. This has a side effect
of permitting linking to binaries built with obsolete MSVC versions.
By default, MSVC 2012 and later require a "safe exception handler table"
in each binary. MinGW-built, 32-bit DLLs lack the relevant exception
handler metadata, so linking to them failed with error LNK2026. Restore
the semantics of MSVC 2010, which omits the table from a given binary if
some linker input lacks metadata. This has no effect on 64-bit builds
or on MSVC 2010 and earlier. Back-patch to 9.3 (all supported
versions).

Commit 3c163a7fc's original choice to ignore all #define symbols whose
names begin with underscore turns out to be too simplistic. On Windows,
some Perl installations are built with -D_USE_32BIT_TIME_T, and we must
absorb that or we get the wrong result for sizeof(PerlInterpreter).
This effectively re-reverts commit ef58b87df, which injected that symbol
in a hacky way, making it apply to all of Postgres not just PL/Perl.
More significantly, it did so on *all* 32-bit Windows builds, even when
the Perl build to be used did not select this option; so that it fails
to work properly with some newer Perl builds.
By making this change, we would be introducing an ABI break in 32-bit
Windows builds; but fortunately we have not used type time_t in any
exported Postgres APIs in a long time. So it should be OK, both for
PL/Perl itself and for third-party extensions, if an extension library
is built with a different _USE_32BIT_TIME_T setting than the core code.
Patch by me, based on research by Ashutosh Sharma and Robert Haas.
Back-patch to all supported branches, as commit 3c163a7fc was.

Adjust the way we detect the locale. As a result the minumum Windows
version supported by VS2015 and later is Windows Vista. Add some tweaks
to remove new compiler warnings. Remove documentation references to the
now obsolete msysGit.

Switching the Windows build scripts to use forward slashes instead of
backslashes has caused a couple of issues in VC builds:
- The file tree list was not correctly generated, build script
generating vcproj file missing tree dependencies when listing items in
Filter.
- VC builds do not accept file paths with forward slashes, perhaps it
could be possible to use a Condition but it seems safer to simply
enforce the file paths to use backslashes in the vcproj files.
- chkpass had an unneeded dependency with libpgport and libpgcommon to
make build succeed but actually it is not necessary as crypt.c is
already listed for this project and should be replaced with a fake name
as it is a unique file.

This makes it possible to run some stages of these build scripts on
non-Windows systems. That way, we can more easily test whether file
moves or makefile changes might break the MSVC build.

The old pattern would match files with strange extensions like *.ry or
*.lpp. Refactor it to only include files with known extensions, and to make
it more readable.
Per Andrew Dunstan's suggestion.
The ASLR in Windows 8/Windows 2012 can break PostgreSQL's shared memory. It
doesn't fail every time (which is explained by the Random part in ASLR), but
can fail with errors abut failing to reserve shared memory region.

This was removed in commit cd00406774,
we're not quite sure why, but there have been reports of crashes due
to AS Perl being built with it when we are not, and it certainly
seems like the right thing to do. There is still some uncertainty
as to why it sometimes fails and sometimes doesn't.
