Thomas Munro c2342a925b Cope with <regex.h> name clashes. macOS 15's SDK pulls in headers related to <regex.h> when we include <xlocale.h>. This causes our own regex_t implementation to clash with the OS's regex_t implementation. Luckily our function names already had pg_ prefixes, but the macros and typenames did not. Include <regex.h> explicitly on all POSIX systems, and fix everything that breaks. Then we can prove that we are capable of fully hiding and replacing the system regex API with our own. 1. Deal with standard-clobbering macros by undefining them all first. POSIX says they are "symbolic constants". If they are macros, this allows us to redefine them. If they are enums or variables, our macros will hide them. 2. Deal with standard-clobbering types by giving our types pg_ prefixes, and then using macros to redirect xxx_t -> pg_xxx_t. After including our "regex/regex.h", the system <regex.h> is hidden, because we've replaced all the standard names. The PostgreSQL source tree and extensions can continue to use standard prefix-less type and macro names, but reach our implementation, if they included our "regex/regex.h" header. Back-patch to all supported branches, so that macOS 15's tool chain can build them.
