It's been some time since we did this, partly because the upstream
snowball project hasn't formally tagged a new release since 2021.
The main motivation for doing it now is to absorb a bug fix
(their commit e322673a841d9abd69994ae8cd20e191090b6ef4), which
prevents a null pointer dereference crash if SN_create_env() gets
a malloc failure at just the wrong point. We'll patch the back
branches with only that change, but we might as well do the full
sync dance on HEAD.
Aside from a bunch of mostly-minor tweaks to existing stemmers, this
update adds a new stemmer for Estonian. It also removes the existing
stemmer for Romanian using ISO-8859-2 encoding. Upstream apparently
concluded that ISO-8859-2 doesn't provide an adequate representation
of some Romanian characters, and the UTF-8 implementation should be
used instead.
While at it, update the README's instructions for doing a sync,
which have not been adjusted during the addition of meson tooling.
Thanks to Maksim Korotkov for discovering the null-pointer
bug and submitting the fix to upstream snowball.

Per git log, the last time someone tried to do something with
pgrminclude was around 2011. Many (not all) of the "pgrminclude
ignore" annotations are of a newer date but seem to have just been
copied around during refactorings and file moves and don't seem to
reflect an actual need anymore.
There have been some parallel experiments with include-what-you-use
(IWYU) annotations, but these don't seem to correspond very strongly
to pgrminclude annotations, so there is no value in keeping the
existing ones even for that kind of thing.
So, wipe them all away. We can always add new ones in the future
based on actual needs.

Make sure that function declarations use names that exactly match the
corresponding names from function definitions in optimizer, parser,
utility, libpq, and "commands" code, as well as in remaining library
code. Do the same for all code related to frontend programs (with the
exception of pg_dump/pg_dumpall related code).
Like other recent commits that cleaned up function parameter names, this
commit was written with help from clang-tidy. Later commits will handle
ecpg and pg_dump/pg_dumpall.

We haven't touched these since text search functionality landed in core
in 2007 :-(. While the upstream project isn't a beehive of activity,
they do make additions and bug fixes from time to time. Update our
copies of these files.
Also update our documentation about how to keep things in sync, since
they're not making distribution tarballs these days. Fortunately,
their source code turns out to be a breeze to build.
Notable changes:
* The non-UTF8 version of the hungarian stemmer now works in LATIN2
not LATIN1.
* New stemmers have appeared for arabic, indonesian, irish, lithuanian,
nepali, and tamil. These all work in UTF8, and the indonesian and
irish ones also work in LATIN1.
(There are some new stemmers that I did not incorporate, mainly because
their names don't match the underlying languages, suggesting that they're
not to be considered mainstream.)
Worth noting: the upstream Nepali dictionary was contributed by
Arthur Zakirov.
initdb forced because the contents of snowball_create.sql have
changed.
Still TODO: see about updating the stopword lists.
Arthur Zakirov, minor mods and doc work by me

Change pg_bsd_indent to follow upstream rules for placement of comments
to the right of code, and remove pgindent hack that caused comments
following #endif to not obey the general rule.
Commit e3860ffa4dd0dad0dd9eea4be9cc1412373a8c89 wasn't actually using
the published version of pg_bsd_indent, but a hacked-up version that
tried to minimize the amount of movement of comments to the right of
code. The situation of interest is where such a comment has to be
moved to the right of its default placement at column 33 because there's
code there. BSD indent has always moved right in units of tab stops
in such cases --- but in the previous incarnation, indent was working
in 8-space tab stops, while now it knows we use 4-space tabs. So the
net result is that in about half the cases, such comments are placed
one tab stop left of before. This is better all around: it leaves
more room on the line for comment text, and it means that in such
cases the comment uniformly starts at the next 4-space tab stop after
the code, rather than sometimes one and sometimes two tabs after.
Also, ensure that comments following #endif are indented the same
as comments following other preprocessor commands such as #else.
That inconsistency turns out to have been self-inflicted damage
from a poorly-thought-through post-indent "fixup" in pgindent.
This patch is much less interesting than the first round of indent
changes, but also bulkier, so I thought it best to separate the effects.

Although there are good reasons for our policy of including postgres.h
as the first #include in every .c file, never from .h files, there are
two places where it seems expedient to violate the policy because the
alternative is to modify externally-supplied .c files. (In the case
of the regexp library, the idea that it's externally-supplied is kind
of at odds with reality, but I haven't entirely given up hope that it
will become a standalone project some day.) Add some comments to make
it explicit that this is a policy violation and provide the reasoning.
In passing, move #include "miscadmin.h" out of regcomp.c and into
regcustom.h, which is where it should be if we're taking this reasoning
seriously at all.

This includes removing tabs after periods in C comments, which was
applied to back branches, so this change should not effect backpatching.

Oleg Bartunov and Teodor Sigaev, but I did a lot of editorializing,
so anything that's broken is probably my fault.
Documentation is nonexistent as yet, but let's land the patch so we can
get some portability testing done.
