  getaddrinfo: fix gai_strerror signature
  
  Several platforms declare gai_strerror to return char* rather than
  const char*.  Worse, on mingw, if UNICODE is defined, it is defined
  to return WCHAR*, which means the result is in unicode but an
  application expecting bytes for characters will only see a one-byte
  answer.
  
  * m4/getaddrinfo.m4 (gl_GETADDRINFO): Detect broken signatures,
  and work around mingw with UNICODE defined.
  (gl_PREREQ_GETADDRINFO): Drop redundant decl check.
  * m4/netdb_h.m4 (gl_NETDB_H_DEFAULTS): Add witness.
  * modules/netdb (Makefile.am): Substitute it.
  * lib/netdb.in.h (gai_strerror): Declare replacement.
  * lib/gai_strerror.c (rpl_gai_strerror): Fix signature.
  * doc/posix-functions/gai_strerror.texi (gai_strerror): Document
  the fix.
