* src/search.c (Pcompile): Add support for NUL bytes in

Perl regular expressions.
* NEWS, doc/grep.1, doc/grep.texi: Change --pcre to --perl-regexp.
* src/grep.c (long_options, usage): Likewise.
* doc/grep.1, doc/grep.texi: Remove pgrep program.
* src/Makefile.am (bin_PROGRAMS): Likewise.
(pgrep_SOURCES): Remove.
* src/grep.c (main): Rename matcher from "pgrep" to "perl".
* src/search.c (matchers): Likewise.
* src/search.c: Do not include stdio.h; no longer needed.
(NILP): Remove.
(sub): No longer static.
(n_pcre): Remove.
(cre): No longer an array.  Present only if HAVE_LIBPCRE.
(extra): New variable.
(Pcompile): Use fatal to report errors.
This also removes a possible core dump.
Add checks (marked FIXME) for restrictions in pcre.
Use pcre_maketables for proper localized behavior.
(Pcompile, Pexecute): Use GNU coding style.
The argument is a single pattern, not a list of patterns separated
by newlines; this is for consistency with grep and egrep.
Use pcre_study for speed.
(Pexecute): Abort if we lack pcre.
Abort if pcre_exec reports an impossible error.
Use code similar to the rest of search.c
to narrow down to the line we've found.
