581c785bf3 Update copyright dates with scripts/update-copyrights 
I used these shell commands:

../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")

and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 7061 files FOO.

I then removed trailing white space from math/tgmath.h,
support/tst-support-open-dev-null-range.c, and
sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following
obscure pre-commit check failure diagnostics from Savannah.  I don't
know why I run into these diagnostics whereas others evidently do not.

900962f37f linux/check_native: Always close socket on return 
The error paths of __check_native would leave the socket FD open on
return, resulting in an FD leak.  Rework function exit paths so that
the fd is always closed on return.

f9a7554009 Change most internal uses of time to __clock_gettime. 
As for gettimeofday, time will be implemented based on clock_gettime
on all platforms and internal code should use clock_gettime
directly.  In addition to removing a layer of indirection, this will
allow us to remove the PLT-bypass gunk for gettimeofday.

The changed code always assumes __clock_gettime (CLOCK_REALTIME)
or __clock_gettime (CLOCK_REALTIME_COARSE) (for Linux case) cannot
fail, using the same rationale for gettimeofday change.  And internal
helper was added (time_now).

Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu,
powerpc64-linux-gnu, and powerpc-linux-gnu.

c181840c93 Consolidate non cancellable close call 
This patch consolidates all the non cancellable close calls to use
the __close_nocancel{_nostatus} identifier.  For non cancellable targets
it will be just a macro to call the default respective symbol while on Linux
will be a internal one.

Also, since it is used on libcrypto it is also exported in GLIBC_PRIVATE
namespace.

af7f7c7ec8 network: recvmsg and sendmsg standard compliance (BZ#16919) 
POSIX specifies that both msghdr::msg_iovlen and msghdr::msg_controllen
to be of size int and socklen_t respectively.  However Linux defines it as
both size_t and for 64-bit it requires some adjustments to make the
functions standard compliance.

This patch fixes it by creating a temporary header and zeroing the pad
fields for 64-bits architecture where size of size_t exceeds the size of
the int.

Also the new recvmsg and sendmsg implementation is only added on libc,
with libpthread only containing a compat symbol.

Tested on x86_64, i686, aarch64, armhf, and powerpc64le.

2eecc8afd0 Terminate process on invalid netlink response from kernel [BZ #12926] 
The recvmsg system calls for netlink sockets have been particularly
prone to picking up unrelated data after a file descriptor race
(where the descriptor is closed and reopened concurrently in a
multi-threaded process, as the result of a file descriptor
management issue elsewhere).  This commit adds additional error
checking and aborts the process if a datagram of unexpected length
(without the netlink header) is received, or an error code which
cannot happen due to the way the netlink socket is used.
