grep: fix some bugs in pattern-grouping speedup
This fixes some bugs in the previous commit,
and should finish the fix for Bug#33249.
* NEWS: Mention fix for Bug#33249.
* src/dfasearch.c (possible_backrefs_in_pattern, regex_compile)
(GEAcompile): In new code, prefer ptrdiff_t to size_t when either
will do, since ptrdiff_t has better error checking. At some point
we should adjust the old code too.
(possible_backrefs_in_pattern): Rename from
find_backref_in_pattern. New arg BS_SAFE. All uses changed.
Fix false negative if a multibyte character ends in a single
'\\' byte, followed by the two bytes '\\', '1'.
(regex_compile): Simplify.
(GEAcompile): Avoid quadratic behavior when reallocating growing
buffers. Fix a couple of bugs in copying pattern data involving
backreferences. Fix another bug in copying pattern metadata
involving backreferences, by removing the need to copy it.
