  getdomainname: Use the system function when possible.
  
  * lib/unistd.in.h: Include <netdb.h>, for getdomainname's declaration.
  (getdomainname): Replace if needed. Provide the declaration if it is
  missing. Don't use _GL_CXXALIAS_SYS_CAST.
  * lib/getdomainname.c: Include <limits.h> and <sys/systeminfo.h>.
  (getdomainname): When the system has getdomainname, call the system
  function. When sysinfo (SI_SRPC_DOMAIN, ...) is possible, use that.
  * m4/getdomainname.m4 (gl_FUNC_GETDOMAINNAME): Require
  gl_HEADER_SYS_SOCKET and gl_HEADER_NETDB. Test whether the function is
  found in libnsl. Look for the declaration also in <netdb.h>. Replace
  the function if its second argument is of type 'int' or if it is found
  in libnsl.
  (gl_PREREQ_GETDOMAINNAME): Define HAVE_GETDOMAINNAME. Check for
  <sys/systeminfo.h> and sysinfo().
  * modules/getdomainname (Depends-on): Add netdb, sys_socket.
  * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Initialize
  HAVE_DECL_GETDOMAINNAME and REPLACE_GETDOMAINNAME instead of
  HAVE_GETDOMAINNAME.
  * modules/unistd (Makefile.am): Substitute HAVE_DECL_GETDOMAINNAME and
  REPLACE_GETDOMAINNAME instead of HAVE_GETDOMAINNAME.
  * doc/glibc-functions/getdomainname.texi: Document the problems with
  the getdomainname declaration.
