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.

Back out yesterday's big merge from the libposix branch, except for the
openat-die.c change that was reviewed and approved by Paul Eggert.
Put the ChangeLog entry at the top, to reflect the order of changes in the
master branch.
Modify gnulib-tool to strip them from generated Makefile.am-s where
they are not needed. Also, replace M4 macro prefixes when requested.
Finally, omit calls to error() for libposix.
Each *.in.h file serves two purposes - provide enough self-contained
content to serve as a replacement for the system header regardless of
the user's compiler, and offer the developer the ability to detect any
gnulib modules that might have been inadvertantly excluded. The
former requires independence from config.h, and routes everything
through a Makefile.am snippet that uses @@ substitution specific to
the modules that were in use, with details learned at configure time.
The latter works by poisoning anything that gnulib did not replace,
but which the developer had natively available, explaining why their
tests passed during development. Poisoning relies on gcc features,
and requires manual triggering by adding -DGNULIB_POSIXCHECK to
CFLAGS; it assumes that <config.h> is properly included. In fact, we
do not want to use @@ substitution for HAVE_DECL_* during poisoning,
because the warning is only relevant for the gnulib modules which were
not included, and thus where the m4 macros to set proper @@ values
have not been run. Furthermore, we only need to poison interfaces
that already have a declaration; if something is not declared, then
the developer wouldn't have been able to link, so their code won't be
using the problematic interface in the first place.
