Paul Eggert 2b778ceb40 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 6694 files FOO.
I then removed trailing white space from benchtests/bench-pthread-locks.c
and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this
diagnostic from Savannah:
remote: *** pre-commit check failed ...
remote: *** error: lines with trailing whitespace found
remote: error: hook declined to update refs/heads/master

/* On PowerPC, in versions of GCC up to at least 4.7.2, a type cast --
which is a IEEE 754-2008 general-computational convertFormat
operation (IEEE 754-2008, 5.4.2) -- does not turn a sNaN into a
qNaN (whilst raising an INVALID exception), which is contrary to
IEEE 754-2008 5.1 and 7.2. This renders certain tests infeasible
in this scenario. <https://gcc.gnu.org/PR56828>. */
