hurd: Fix `getifaddrs' and `freeifaddrs' symbol exposition
from `freeaddrinfo'. `getifaddrs' and `freeifaddrs' are not in POSIX, they should not be exposed along `freeaddrinfo' (through `__check_pf') which is POSIX. * include/ifaddrs.h (__getifaddrs, __freeifaddrs): New declarations, and use libc_hidden_def on them. * inet/ifaddrs.c (__getifaddrs, __freeifaddrs): Use libc_hidden_def on them. * sysdeps/gnu/ifaddrs.c (__getifaddrs, __freeifaddrs): Likewise. * inet/check_pf.c (__check_pf): Use __getifaddrs and __freeifaddrs instead of getifaddrs and freeifaddrs.
