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
' \
  $(find $(git ls-files) -prune -type f \
      ! -name '*.po' \
      ! -name 'ChangeLog*' \
      ! -path COPYING ! -path COPYING.LIB \
      ! -path manual/fdl-1.3.texi ! -path manual/lgpl-2.1.texi \
      ! -path manual/texinfo.tex ! -path scripts/config.guess \
      ! -path scripts/config.sub ! -path scripts/install-sh \
      ! -path scripts/mkinstalldirs ! -path scripts/move-if-change \
      ! -path INSTALL ! -path  locale/programs/charmap-kw.h \
      ! -path po/libc.pot ! -path sysdeps/gnu/errlist.c \
      ! '(' -name configure \
            -execdir test -f configure.ac -o -f configure.in ';' ')' \
      ! '(' -name preconfigure \
            -execdir test -f preconfigure.ac ';' ')' \
      -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 \
    sysdeps/csky/configure \
    sysdeps/hppa/configure \
    sysdeps/riscv/configure \
    sysdeps/unix/sysv/linux/csky/configure
  # Omit changes that caused a pre-commit check to fail like this:
  # remote: *** error: sysdeps/powerpc/powerpc64/ppc-mcount.S: trailing lines
  git checkout -f \
    sysdeps/powerpc/powerpc64/ppc-mcount.S \
    sysdeps/unix/sysv/linux/s390/s390-64/syscall.S
  # Omit change that caused a pre-commit check to fail like this:
  # remote: *** error: sysdeps/sparc/sparc64/multiarch/memcpy-ultra3.S: last line does not end in newline
  git checkout -f sysdeps/sparc/sparc64/multiarch/memcpy-ultra3.S

afe4de7d28 nptl: Add POSIX-proposed pthread_cond_clockwait 
Add:

 int pthread_cond_clockwait (pthread_cond_t *cond,
                             pthread_mutex_t *mutex,
                             clockid_t clockid,
                             const struct timespec *abstime)

which behaves just like pthread_cond_timedwait except it always measures
abstime against the supplied clockid. Currently supports CLOCK_REALTIME
and
CLOCK_MONOTONIC and returns EINVAL if any other clock is specified.

Includes feedback from many others. This function was originally
proposed[1] as pthread_cond_timedwaitonclock_np, but The Austin Group
preferred the new name.

	* nptl/Makefile: Add tst-cond26 and tst-cond27
	* nptl/Versions (GLIBC_2.30): Add pthread_cond_clockwait
	* sysdeps/nptl/pthread.h: Likewise
	* nptl/forward.c: Add __pthread_cond_clockwait
	* nptl/forward.c: Likewise
	* nptl/pthreadP.h: Likewise
	* sysdeps/nptl/pthread-functions.h: Likewise
	* nptl/pthread_cond_wait.c (__pthread_cond_wait_common): Add
	clockid parameter and comment describing why we don't need to
	check
	its value. Use that value when calling
	futex_abstimed_wait_cancelable rather than reading the clock
	from
	the flags. (__pthread_cond_wait): Pass unused clockid parameter.
	(__pthread_cond_timedwait): Read clock from flags and pass it to
	__pthread_cond_wait_common. (__pthread_cond_clockwait): Add new
	function with weak alias from pthread_cond_clockwait.

	* nptl/tst-cond11.c (run_test): Support testing
	pthread_cond_clockwait too by using a special magic
	CLOCK_USE_ATTR_CLOCK value to determine whether to call
	pthread_cond_timedwait or pthread_cond_clockwait. (do_test):
	Pass
	CLOCK_USE_ATTR_CLOCK for existing tests, and add new tests using
	all combinations of CLOCK_MONOTONIC and CLOCK_REALTIME.
	* ntpl/tst-cond26.c: New test for passing unsupported and
	* invalid
	clocks to pthread_cond_clockwait.
	* nptl/tst-cond27.c: Add test similar to tst-cond5.c, but using
	struct timespec and pthread_cond_clockwait.
	* manual/threads.texi: Document pthread_cond_clockwait. The
	* comment
	was provided by Carlos O'Donell.
