Thomas Munro 65f438471b Fix gai_strerror() thread-safety on Windows. 
Commit 5579388d removed code that supplied a fallback implementation of
getaddrinfo(), which was dead code on modern systems.  One tiny piece of
the removed code was still doing something useful on Windows, though:
that OS's own gai_strerror()/gai_strerrorA() function returns a pointer
to a static buffer that it overwrites each time, so it's not
thread-safe.  In rare circumstances, a multi-threaded client program
could get an incorrect or corrupted error message.

Restore the replacement gai_strerror() function, though now that it's
only for Windows we can put it into a win32-specific file and cut it
down to the errors that Windows documents.  The error messages here are
taken from FreeBSD, because Windows' own messages seemed too verbose.

Back-patch to 16.
