All previously forwarded functions are now implemented in libc.

3fec7f18bf nptl: Move pthread_once and __pthread_once into libc 
And also the fork generation counter, __fork_generation.  This
eliminates the need for __fork_generation_pointer.

call_once remains in libpthread and calls the exported __pthread_once
symbol.

pthread_once and __pthread_once have been moved using
scripts/move-symbol-to-libc.py.

64786a7090 fork.h: replace with register-atfork.h 
UNREGISTER_ATFORK is now defined for all ports in register-atfork.h, so most
previous includes of fork.h actually only need register-atfork.h now, and
cxa_finalize.c does not need an ifdef UNREGISTER_ATFORK any more.

The nptl-specific fork generation counters can then go to pthreadP.h, and
fork.h be removed.

Checked on x86_64-linux-gnu and i686-gnu.

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

5a82c74822 Prefer https to http for gnu.org and fsf.org URLs 
Also, change sources.redhat.com to sourceware.org.
This patch was automatically generated by running the following shell
script, which uses GNU sed, and which avoids modifying files imported
from upstream:

sed -ri '
  s,(http|ftp)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g
  s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g

      ! '(' -name preconfigure \

      -print)

and then by running 'make dist-prepare' to regenerate files built
from the altered files, and then executing the following to cleanup:

  chmod a+x sysdeps/unix/sysv/linux/riscv/configure
  # Omit irrelevant whitespace and comment-only changes,
  # perhaps from a slightly-different Autoconf version.
  git checkout -f \

2827ab990a libc: Extend __libc_freeres framework (Bug 23329). 
The __libc_freeres framework does not extend to non-libc.so objects.
This causes problems in general for valgrind and mtrace detecting
unfreed objects in both libdl.so and libpthread.so.  This change is
a pre-requisite to properly moving the malloc hooks out of malloc
since such a move now requires precise accounting of all allocated
data before destructors are run.

This commit adds a proper hook in libc.so.6 for both libdl.so and
for libpthread.so, this ensures that shm-directory.c which uses
freeit () to free memory is called properly.  We also remove the
nptl_freeres hook and fall back to using weak-ref-and-check idiom
for a loaded libpthread.so, thus making this process similar for
all DSOs.

Lastly we follow best practice and use explicit free calls for
both libdl.so and libpthread.so instead of the generic hook process
which has undefined order.

Tested on x86_64 with no regressions.

80d9be8122 Convert miscellaneous function definitions to prototype style. 
This patch converts various miscellaneous functions definitions in
glibc, found with grep and not covered by my previous scripted
conversions, from old-style K&R to prototype-style.  These changes
were made manually.  This is not necessarily exhaustive as formatting
variants may have prevented my grep from finding some such
definitions.

Regarding the changes to files from GMP, they may originally have been
omitted when removing __STDC__ conditionals because of the files
coming from another package, but (a) GMP no longer has __STDC__
conditionals there anyway and (b) we don't try to keep these files
verbatim in sync with GMP (and there are licensing differences), so
making the change to them in glibc seems reasonable.

Tested for x86_64 and x86 (testsuite - this patch affects files
containing assertions).

ec999b8e5e Move bits/libc-lock.h and bits/libc-lockP.h out of bits/ (bug 14912). 
It was noted in
<https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the
bits/*.h naming scheme should only be used for installed headers.
This patch renames bits/libc-lock.h to plain libc-lock.h and
bits/libc-lockP.h to plain libc-lockP.h to follow that convention.

Note that I don't know where libc-lockP.h comes from for Hurd (the
Hurd libc-lock.h includes libc-lockP.h, but the only libc-lockP.h in
the glibc source tree is for NPTL) - some unmerged patch? - but I
updated the #include in the Hurd libc-lock.h anyway.

Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by the patch).
