When a function definition has preproc directives in its body, it
can't correctly parse into a function_definition. This fix tries to
recognize this case and highlight the function_declarator correctly.

(c-ts-mode--emacs-current-defun-name): Doc fixes. (Bug#62825)
The DEFUN is hard to incorporate because it's made of two nodes rather
than one, and most tree-sitter functionalities assume a defun is one
node. I fixed the indent-defun and add-log functionality, but
beginning/end-of-defun and imenu still don't recognize DEFUN.
* lisp/progmodes/c-ts-mode.el (c-ts-mode-emacs-devel): New variable.

"#elif" and "#else".
* test/lisp/progmodes/c-ts-mode-resources/indent-preproc.erts: Add an
"#elif" to the test.
Mentioned in bug#61893, although not the subject of it.
* lisp/progmodes/c-ts-mode.el:
(c-ts-mode--anchor-prev-sibling): Fix the child index for preproc_else

New test.
Not the subject of it, but mentioned in bug#61893.
* lisp/progmodes/c-ts-mode.el (c-ts-mode--anchor-prev-sibling): Skip
the sibling if it doesn't start on it's own line.
* test/lisp/progmodes/c-ts-mode-resources/indent.erts: New test.
Mentioned in bug#61893, although not the subject of that report. This
change fixes indentation for nested directives. For example, when the
directive involves elif and the like, the elif is nested in the if
directive, so simply using grand-parent and great-grand-parent for
anchor is insufficient, because the nesting can grow arbitrarily.
The test added also covers the last preproc fix.
* lisp/progmodes/c-ts-mode.el:
(c-ts-mode--standalone-parent-skip-preproc): New function.
(c-ts-mode--indent-styles): New rules.
* test/lisp/progmodes/c-ts-mode-resources/indent-preproc.erts: New test.
Originally our c-ts-mode--anchor-prev-sibling only specially handled
labeled_statements, now we add special case for preproc in the similar
fasion: instead of using the preproc directive as anchor, use the last
statement in that preproc as the anchor. Thus effectively ignore the
preproc.
There should be an accompanying test, but there are some problem in
the elif preproc directive indent so it would pass, we'll add the test
when that is fixed.
* lisp/progmodes/c-ts-mode.el:
(c-ts-mode--anchor-prev-sibling): Add special case for preproc
directives.
* lisp/progmodes/c-ts-mode.el (c-ts-mode--indent-styles): Make the
"rest sibling" matchers catch the case where NODE is nil, when
indenting an empty line.
* test/lisp/progmodes/c-ts-mode-resources/indent.erts: New test.
Now it handles the case where NODE is nil when indenting an empty
line: it tries to get the previous sibling nonetheless.
* lisp/progmodes/c-ts-mode.el (c-ts-mode--anchor-prev-sibling):
* lisp/treesit.el (treesit-simple-indent-presets): Add an or form to
handle more cases.
* lisp/progmodes/c-ts-mode.el (c-ts-mode-toggle-comment-style):
Actually implement the optional numeric arg mentioned in the
docstring.
Copyright-paperwork-exempt: yes
* lisp/font-lock.el (font-lock-variable-use-face)
(font-lock-property-use-face): Rename from font-lock-variable-ref-face
and font-lock-property-ref-face. Update all references (bug#61655).
When writing c-ts-mode Theo used parent-bol which works well except
one case:
1 for (int i=0;
2 i < 5;
3 i++) {
4 func(i);
5 }
In this case, when indenting "func(i)", parent-bol returns the start
of "i++" on line 3, instead of the "correct" anchor, the start of
"for" on line 1. parent-bol would have worked if the "for (...) {"
part is in one line.
To support this case I tried numerous things and added a bunch of
stuff, culminating in c-ts-common-statement-offset. It's complicated,
requires extra setup, and slow.
Not anymore! I think the new anchor standalone-parent really captures
the logic behind how people expect indentation to work. It's simple
and fast, and requires no setup.

"declaration_list" a block. (Bug#61635)
* test/lisp/progmodes/c-ts-mode-resources/indent.erts (Code): Add a
test case.
* lisp/progmodes/c-ts-mode.el (c-ts-mode--indent-styles): Make sure we

It looks like there are few if no other cases where we get this
particular error in the AST than with insertion of '#'.
Consider:
```
int
main()
{
|
}
```
If we only add '#' the AST yields (ERROR (ERROR)), which we can
exploit to hook onto electric indent. The end result should be the
hashtag anchored to column 0.
* lisp/progmodes/c-ts-mode.el (c-ts-mode--indent-styles): New rule.
(c-ts-base-mode): Add # to electric-indent-chars.
Sign, ok, there's another edge case: else if statements. Because
"else if" is usually implemented as just another if statement nested
in the else branch, this creates additional levels that indentation
needs to ignore.
I converted c-ts-common-indent-block-type-regexp +
c-ts-common-indent-bracketless-type-regexp into a new, more flexible
variable, c-ts-common-indent-type-regexp-alist, to avoid adding yet
more variables in order to recognize else and if statements.

(c-ts-common-indent-block-type-regexp)

"else if" special case. Also merge the code of
c-ts-mode--fix-bracketless-indent, because now the code is much more
succinct.
(c-ts-mode--fix-bracketless-indent): Merge into
c-ts-common-statement-offset.

(c-ts-base-mode): Setup c-ts-common-indent-type-regexp-alist.
