Copy regex_internal.h from Gnulib
Sync this file from Gnulib, thus incorporating the following
fix for a bug with regexps with 16 or more subexpressions:
* posix/regex_internal.h (struct re_backref_cache_entry):
Use bitset_word_t as the type of eps_reachable_subexps_map,
instead of unsigned short int. This fixes a bug I introduced
to glibc in 2005-09-28T17:33:18Z!drepper@redhat.com (glibc commit
2c05d33f90861d074dc12808dafbde30f487b1a0, BZ #1302).
Remove unused member 'unused'.
