* src/fileio.c (Finsert_file_contents): Store st_size,
not file_size_hint, into current_buffer->modtime_size,
since modtime_size is compared to a later st_size, not
to the actual file size. Simplify buffer overflow detection
from file size, since this occurred only on regular files.

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).

Be more systematic about putting space before paren in calls,
and in avoiding unnecessary parentheses in macros.
This was partly inspired by my wading through gcc -E output
while debugging something else, and seeing too many parens.
This patch does not change the generated .o files on my platform.

(Fre__describe_compiled): Adjust C queries to `case-fold-search' value

* doc/lispref/internals.texi (Buffer Internals): Do not list

See https://debbugs.gnu.org/cgi/bugreport.cgi?bug=66117#259
When used as buffer slot, let-binding `case-fold-search' would scale
with the number of live buffers and can be slow. This change makes
let-binding much faster at the cost of slightly slower `set-buffer'.

In character.h, replace macros with inline functions or enums
when this is easy. This improves maintainability and
on my platform (Fedora 31 x86-64, gcc -O2) improved CPU
performance very slightly (0.3%) on ‘make compile-always’.
* src/buffer.h (SANE_TAB_WIDTH, CHARACTER_WIDTH):
Move here from character.h, and make them inline functions.
Tune CHARACTER_WIDTH so that ASCII_CHAR_WIDTH is no longer needed.

Move here from character.h.

(Fkill_buffer): Don't check indirect dead buffers.
Set the undo_list before we remove ourselves from the list of live buffers.
(Fbuffer_swap_text, Fset_buffer_multibyte): Don't check indirect dead

the code is simpler and treats bignums consistently with fixnums.
* src/buffer.h (CHECK_FIXNUM_COERCE_MARKER): Define here
rather than in lisp.h, and reimplement in terms of fix_position
so that it treats bignums consistently with fixnums.
