  passfd: allow compilation on mingw
  
  The passfd module now skips on mingw, rather than failing to compile.
  
  It may be nice to add a sendmsg and recvmsg module in the future,
  but for now passfd is the only client that cares.
  
  * modules/sys_socket (Depends-on): Add sys_uio.
  * lib/sys_socket.in.h [!@HAVE_SYS_SOCKET_H@]: Use it for struct
  iovec and a minimal struct msghdr.
  * tests/test-sys_socket.c (main): Enhance test.
  * m4/afunix.m4 (gl_SOCKET_AFUNIX): Detect recvmsg/sendmsg.
  * lib/passfd.c (include): Drop <sys/uio.h>; <sys/sockets.h> is
  guaranteed to provide what we need.
  (sendmsg, recvmsg): Declare fallbacks if we lack sendmsg.
  * modules/passfd-tests (Depends-on): Add sys_wait.
  * tests/test-passfd.c (main): Skip test on mingw, for now.
  * doc/posix-headers/sys_socket.texi (sys/socket.h): Document the
  partial 'struct msghdr' implementation.
