Sync functions checks

Removed unused checks:
- mbsinit check removed, HAVE_MBSINIT removed (not used in php-src)
- mempcpy check removed, HAVE_MEMPCPY removed (not used in php-src anymore since
  560ed89bfbb56526251e9bd2fbcb27e5932641d8 which uses PHP's own implementation)
- strpncpy check removed, added via a8c9e893b6911c785f698d724b2ff61e7aebb737 and
  not used.
- setpgid check removed since HAVE_SETPGID is not used

Moved to a central configure.ac:
- fpclass
- mbrlen moved to configure.ac (since the HAVE_MBRLEN is used accross the php-src)
- sigprocmask
- getcwd
- getwd
- glob
- strfmon
- nice

Duplicated checks removed:
- gethostname
- getlogin
- getpwuid_r
- socketpair

- mprotect check simplified
