22999b2f0f string: Add libc_hidden_proto for memrchr 
Although static linker can optimize it to local call, it follows the
internal scheme to provide hidden proto and definitions.

9d4fa7a1ca string: Improve generic memrchr 
New algorithm read the lastaligned address and mask off the unwanted
bytes.  The loop now read word-aligned address and check using the
has_eq macro.

Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc-linux-gnu,
and powerpc64-linux-gnu by removing the arch-specific assembly
implementation and disabling multi-arch (it covers both LE and BE
for 64 and 32 bits).

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.

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

      -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 \

f17a42333f Do not use __ptr_t. 
sys/cdefs.h has a macro __ptr_t, which a few places in glibc use
instead of void *.  void * is a well-understood standard type for that
purpose and in a post-C89 context there is no need for a macro for it;
this patch changes those places to use void * directly instead.

Unlike __long_double_t, __ptr_t is widely used outside glibc (or at
least has many hits on codesearch.debian.net).  I don't know how many
of those uses would break if sys/cdefs.h ceased to define the macro,
but there's enough risk that this patch leaves the definition and just
removes the uses within glibc; removal of the definition can be
considered separately if desired.

Tested for x86_64, and with build-many-glibcs.py.

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).

	prototype-style function definition.  Use internal_function.
