Paul Eggert 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.

remote: *** 912-#endif
remote: *** 913:
remote: *** 914-
remote: *** error: lines with trailing whitespace found
...
remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines

/* This is used from only one place: dl-misc.c:_dl_debug_vdprintf.
Hence it's in a header with the expectation it will be inlined.
This is writev, but with a constraint added and others loosened:
1. Under RTLD_PRIVATE_ERRNO, it must not clobber the private errno
when another thread holds the dl_load_lock.
2. It is not obliged to detect and report errors at all.
3. It's not really obliged to deliver a single atomic write
(though it may be preferable). */
