Add line-column tracking for tree-sitter parsers. Copied from
comments in treesit.c:
Technically we had to send tree-sitter the line and column
position of each edit. But in practice we just send it dummy
values, because tree-sitter doesn't use it for parsing and
mostly just carries the line and column positions around and
return it when e.g. reporting node positions[1]. This has
been working fine until we encountered grammars that actually
utilizes the line and column information for
parsing (Haskell)[2].
[1] https://github.com/tree-sitter/tree-sitter/issues/445
[2] https://github.com/tree-sitter/tree-sitter/issues/4001
So now we have to keep track of line and column positions and
pass valid values to tree-sitter. (It adds quite some
complexity, but only linearly; one can ignore all the linecol
stuff when trying to understand treesit code and then come
back to it later.) Eli convinced me to disable tracking by
default, and only enable it for languages that needs it. So
the buffer starts out not tracking linecol. And when a
parser is created, if the language is in
treesit-languages-require-line-column-tracking, we enable
tracking in the buffer, and enable tracking for the parser.
To simplify things, once a buffer starts tracking linecol, it
never disables tracking, even if parsers that need tracking
are all deleted; and for parsers, tracking is determined at
creation time, if it starts out tracking/non-tracking, it
stays that way, regardless of later changes to
treesit-languages-require-line-column-tracking.
To make calculating line/column positons fast, we store
linecol caches for begv, point, and zv in the
buffer (buf->ts_linecol_cache_xxx); and in the parser object,
we store linecol cache for visible beg/end of that parser.
In buffer editing functions, we need the linecol for
start/old_end/new_end, those can be calculated by scanning
newlines (treesit_linecol_of_pos) from the buffer point
cache, which should be always near the point. And we usually
set the calculated linecol of new_end back to the buffer
point cache.
We also need to calculate linecol for the visible_beg/end for
each parser, and linecol for the buffer's begv/zv, these
positions are usually far from point, so we have caches for
all of them (in either the parser object or the buffer).
These positions are far from point, so it's inefficient to
scan newlines from point to there to get up-to-date linecol
for them; but in the same time, because they're far and
outside the changed region, we can calculate their change in
line and column number by simply counting how much newlines
are added/removed in the changed
region (compute_new_linecol_by_change).

Some explanation: Fsubst_char_in_region used to have a branch,
one branch path calls replace_range, one branch path modifies
the buffer directly. replace_range already calls
treesit_record_change within it, so we needed to make sure we
only call treesit_record_change in the other branch path.
After I added the call to treesit_record_change, some changes
are made to Fsubst_char_in_region, and the branch was removed.
So no wonder Stefan had the confusion and wrote the FIXME note.
Now that the branch is gone, we can indeed call
treesit_record_change in the end like signal_after_change.
* src/editfns.c (Fsubst_char_in_region): Move to end.
Among other users, let-alist widely uses symbols which start with a ".".
Make those symbols print more nicely by tweaking the escaping rules in
print_object to not escape a leading "." followed by a letter. This is
a conservative change to avoid constraining future lexer changes.
This is a followup to 637dde4aba, which
removed some unnecessary escaping of "." and "?" when printing symbols
in prin1. (Actually, if we always escaped "?" (which was the case
before 637dde4aba) then "." only ever needs to be escaped when
string_to_number returns non-nil. So 637dde4aba could have just
dropped the escaping of "." with no other changes, if it didn't also
remove escaping of "?")

(Bug#77171)
Work around a bug in GnuTLS 3.7.11 and earlier: when built
statically, its mistakenly exports symbols hash_lookup and
hash_string, which collide with Emacs symbols of the same name,
preventing temacs from linking statically. Problem reported by
Greg A. Woods (Bug#77476).
Because GnuTLS never uses hash_lookup or hash_string this issue
ordinarily doesn’t seem to prevent temacs from linking to GnuTLS
on GNU/Linux, as it’s linked dynamically and the dynamic linker
never needs to resolve references to either symbol. However, I
suppose a clash or bug could occur even with dynamic linking if
Emacs later loads a module that uses either symbol.
Although GnuTLS should be fixed, Emacs should link statically to
current and older GnuTLS versions in the meantime, and it should
avoid potential problems with dynamic linking. Renaming the two
clashing names is an easy way to do this. For consistency with
the new name for hash_lookup, also rename hash_lookup_with_hash
and hash_lookup_get_hash.
* src/fns.c (hash_find_with_hash): Rename from hash_lookup_with_hash.
(hash_find): Rename from hash_lookup.
(hash_find_get_hash): Rename from hash_lookup_get_hash.
(hash_char_array): Rename from hash_string.

at the end of the replacement than it is to keep point at the
beginning of the replacement.

The compile-time option XMALLOC_BLOCK_INPUT_CHECK was added in
2012 (commit 4d7e6e51dd) to allow blocking input during
malloc-family calls, in case any issues arose from related
changes in Emacs 24.3. However, it has not been referenced on
emacs-devel or the bug tracker in over a decade.
It is clear that we do not need it, as our signal handlers do not
allocate memory. Removing it simplifies the allocation function
wrappers and eliminates dead debug code.
