passfd: speed up configure and drop unused code
Ultimately, it would be nice to provide a sendmsg and recvmsg module,
and have those provide a replacement struct msghdr and silently
convert msg_accrights into the replacement struct's msg_control, when
targeting older BSD. But until that point in time, this is a nice
cleanup.
SCM_RIGHTS really only works on Unix sockets; however, there is
nothing in passfd.c that needs to be hard-coded to this (rather,
the hard-coding of the address family is done externally when
the socket or socketpair is created).
* m4/afunix.m4 (gl_SOCKET_AFUNIX): Rename...
* m4/passfd.m4 (gl_PASSFD): ...to something more fitting of
its use. Drop test for setting unused HAVE_UNIXSOCKET_SCM_RIGHTS.
Instead of probing at configure for unix_scm_rights_bsd44_way,
instead probe for CMSG_FIRSTHDR at compile time. Simplify BSD 4.3
check to a struct member probe.
* lib/passfd.c (includes): Nothing here requires <sys/un.h>.
(sendfd, recvfd): Update preprocessor checks.
* modules/passfd (Files): Reflect rename, and drop unused file.
(Depends-on): Drop unused dependency.

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.

passfd: fix scoping bug
The scoping bug was the cause of the NetBSD hang.
* lib/passfd.c (sendfd, passfd): Don't let buf go out of scope
before sendmsg/recvmsg.

passfd: standardize coding conventions
* m4/afunix.m4 (gl_SOCKET_AFUNIX): Drop check for something that
can be learned at compile time.
* lib/passfd.c (MSG_CMSG_CLOEXEC): Reduce number of in-function
ifdefs.
(passfd, recvfd): Follow gnulib code conventions.

passfd: fix incorrect sendmsg arguments
The unit test hung on NetBSD, which pointed out a couple of bugs.
* lib/passfd.c (sendfd): Avoid uninitialized msg_flags field, and
incorrect msg_controllen value.
* modules/passfd-tests (Depends-on): Check for alarm.
* tests/test-passfd.c (main) [HAVE_DECL_ALARM]: Avoid hanging test.

passfd module, part 2, tweaks.
* modules/passfd (Files): Reorder.
(Depends-on): Remove errno.
(Include): Remove <sys/socket.h>, <sys/un.h>.
* lib/passfd.h: Use a GPLv3+ header. Make C++ safe.
* lib/passfd.c: Untabify. Use a GPLv3+ header. Really include the
specification header. Include <sys/socket.h> always. Don't include
<winsock2.h>. Use "#if HAVE_..." instead of "#ifdef HAVE_...".
(sendfd): Clarify that it sets errno when it fails.
(recvfd): Fix specification.
