switched coreutils to new regex implementation

[Paul Eggert]

I installed the following to sync coreutils from gnulib with respect
to regex.  This is a big patch, so I won't enclose the stuff that's
identical to yesterday's gnulib patch.  You can find the gnulib patch
here:

http://lists.gnu.org/archive/html/bug-gnulib/2005-07/msg00041.html

and here are the changes needed to integrate it into coreutils, which
I installed just now:

        Switch to Isamu Hasegawa's implementation of regex, which is
        now in gnulib.
        * lib/regcomp.c, lib/regex_internal.c, lib/regex_internal.h:
        * lib/regexec.c:
        New files, from gnulib.
        * lib/regex.h, lib/regex.c: Sync from gnulib.
        * lib/Makefile.am (libcoreutils_a_SOURCES): Remove regex.h; gnulib
        now does this automatically for us.
        * lib/.cppi-disable: Add regcomp.c, regex_internal.c, regex_internal.h.
