This avoids aliasing issues with GCC 6 in -fno-strict-aliasing
mode. (With implicit padding, not all data is copied.)
This change makes it explicit that struct sockaddr_storage is
only 126 bytes large on m68k (unlike elsewhere, where we end up
with the requested 128 bytes). The new test case makes sure that
this does not happen on other architectures.
This patch updates sysdeps/unix/sysv/linux/bits/socket.h for new
constants added in Linux 4.6. AF_KCM / PF_KCM are added. SOL_KCM is
new, and I added a lot of SOL_* values postdating the last one present
in the header, since I saw no apparent reason for the set in glibc to
stop at SOL_IRDA. MSG_BATCH is added; Linux also has
MSG_SENDPAGE_NOTLAST which is not in glibc, but given the comment
starts "sendpage() internal" I presume it's correct for it not to be
in glibc.
(Note that this is a case where the Linux kernel header with userspace
relevant values is *not* a uapi header but include/linux/socket.h - I
don't know why, but at least this header, as well as uapi headers,
needs reviewing for glibc-relevant changes each release.)
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

This patch updates installed glibc headers for new definitions from
Linux 4.0 and 4.1 that seem relevant to glibc headers. In addition, I
noticed that PF_IB / AF_IB, added in Linux 3.11, were missing for no
obvious reason, so added those as well.
Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by the patch).

Use int32_t for ll_time.

Use int32_t instead of long int for ut_session.
Use an anonymous struct with 32-bit fields for ut_tv.

Other than the previously incorrect sign of msg_iovlen, this is a
no-op on 32-bit platforms. On 64-bit platforms it makes this header
match their layouts as well, so the following are now identical to it.
