Problem: Existing cmdline completion for :highlight was barebone and
only completed the highlight group names.
Solution: Implement full completion for the highlight group arguments
such as guifg and cterm. If the user tries to complete
immediately after the '=' (e.g. `hi Normal guifg=<Tab>`), the
completion will fill in the existing value, similar to how
cmdline completion for options work (Yee Cheng Chin).

Problem: Syntax engine interpreted contains=TOP as matching nothing
inside included files, since :syn-include forces HL_CONTAINED
on for every included item. After 8.2.2761, interprets
contains=TOP as contains=@INCLUDED, which is also not correct
since it doesn't respect exclusions, and doesn't work if there
is no @INCLUDED cluster.
Solution: revert patch 8.2.2761, instead track groups that have had
HL_CONTAINED forced, and interpret contains=TOP and
contains=CONTAINED using this. (Theodore Dubois)

Problem: Coverity warns about a few potential issues
Solution: Fix those issues (see details below)
1) Fix overflow warning in highlight.c
This happens because we are comparing int with long
and assign a potential long value to an int, which
could cause an overflow. So add some casts to ensure
the value fits into an int.
2) Fix Overflow warning in shift_line().
This happens because we are performing a division/modulo
operation of a long type by an int type and assign the result
to an int, which could then overflow. So before performing
the operation, trim the long to value to at most max int value,
so that it can't overflow.
3) Fix overflow warning in syn_list_cluster in syntax.c
This is essential the same issue as 1)
4) not checking the return value of vim_mkdir() in spellfile.c
Creating the spell directory could fail. Handle this case
and return early in this case.
5) qsort() may deref a NULL pointer when fuzzy match does not
return a result. Fix this by checking that the accessed growarray
fuzzy_indices actually contains data. If not we can silently skip
the qsort() and related logic.

Problem: More code can use ml_get_buf_len() instead of STRLEN().
Solution: Change more STRLEN() calls to ml_get_buf_len(). Also do not
set ml_line_textlen in ml_replace_len() if "has_props" is set,
because "len_arg" also includes the size of text properties in
that case. (zeertzjq)

Problem: "clear" macros are not always used.
Solution: Use ALLOC_ONE, VIM_CLEAR, CLEAR_POINTER and CLEAR_FIELD in more
places. (Yegappan Lakshmanan, closes#12104)
Problem: FOR_ALL_ macros are defined in an unexpected file.
Solution: Move FOR_ALL_ macros to macros.h. Add FOR_ALL_HASHTAB_ITEMS.

Problem: Syntax highlighting disabled when using synID() in searchpair()
skip expression and it times out. (Jaehwang Jung)
Solution: Add the redrawtime_limit_set flag. (closes#10562)
Problem: Vim9: 'cpo' can become empty.
Solution: Use empty_option instead of an empty string. Update quickfix
buffer after restoring 'cpo'. (closes#7608)
Problem: Transparent syntax item uses start/end of containing region.
Solution: Do not change the startpos and endpos of a transparent region to
that of its containing region. (Adrian Ghizaru, closes#7349,
closes#7391)
Problem: Many type casts are used for vim_strnsave().
Solution: Make the length argument size_t instead of int. (Ken Takata,
closes#5633) Remove some type casts.
Problem: Syntax foldlevel is taken from the start of the line.
Solution: Add ":syn foldlevel" to be able to use the minimal foldlevel in
the line. (Brad King, closes#6087)
