regex: merge patches from libc

2015-10-21  Joseph Myers  <joseph@codesourcery.com>
2015-10-20  Joseph Myers  <joseph@codesourcery.com>
Convert miscellaneous function definitions to prototype style.
* lib/regcomp.c (re_compile_pattern, re_set_syntax)
(re_compile_fastmap, regcomp, regerror, regfree, re_comp):
* lib/regexec.c (regexec, re_match, re_search, re_match_2, re_search_2)
(re_search_2_stub, re_search_stub, re_set_registers, re_exec)
(re_search_internal):
Convert to prototype-style function definition.
Use internal_function for internal functions.
