exclude: add support for posix regexps
This commit adds support for POSIX extended regular expressions
and fixes a long-standing memory leak (pattern buffer was never
freed). It also implements a new interface function to read
exclude patterns from a FILE, which passes an additional parameter
to its callback function, thereby allowing to preserve its state
between invocations.
* lib/exclude.c (struct patopts): Pack regex and pattern into union.
(pattern_buffer): New struct.
(exclude): New member patbuf.
(exclude_add_pattern_buffer): New function.
(free_exclude_segment): Free regexps.
(free_exclude): Free allocated pattern buffers.
(exclude_patopts): New function.
(file_pattern_matches): Use exclude_patopts.
(add_exclude): support regexps.
(add_exclude_fp): New function.
(add_exclude_file): Rewrite using add_exclude_fp.
(fnmatch_pattern_has_wildcards): Support posix extended regexps.
* lib/exclude.h (EXCLUDE_REGEX, EXCLUDE_ALLOC): New flags.
(add_exclude_fp)
(exclude_add_pattern_buffer): New prototypes.
* modules/exclude: Depends on regex and filename.
