nptl: Move pthread_equal implementation into libc
Commit Message
Tested on x86_64-linux-gnu and i686-linux-gnu, and compile-tested using
build-many-glibcs.py. No regressions related to this change.
Thanks,

We only need one implementation. The indirection from libc to
libpthread is completely unnecessary.
My goal is to get rid of the forwarders than do not depend on internal
libpthread state fairly quickly, and then move the rest once the
__libc_single_threaded flag has been around for a while (so that
applications do not have to use pthread_create or something else for
guiding optimization of atomics).
Where appropriate, the remaining implementations should have fast
paths which avoid atomics. The old approach, where the libpthread
implementations do not have fast paths and the libc implementations do
not use atomics, fail to optimize the rather common case of
single-threaded processes that load libpthread via a library
dependency. We also have subtle bugs because process-shared mutexes
cannot be locked and unlocked properly unless the program is linked
against libpthread, but nothing actually enforces that if the mutexes
are created by a different process.

FYI, I did some work on this last year, but I never posted the
patches, because I discovered that a complete job would be easier if
we first merged Adhemerval's cancellation overhaul. That's still
waiting for review, right? We should really get that done _anyway_...

I think there isn't an inherent dependency, just fewer textual changes
as the result.

I can try to review it this cycle.
Thanks,

I plan to push the sigcontext.h [1], this simplifies the code to parse
the program counter from the signal handler on all architectures. It
is a large patch unfortunately, however it is mainly a refactor so it
should be easier to get some review.
I have been working on BZ#12683 sporadically and do hope we could finally
make it upstream for next release. I tested it on more architectures
recently (ia64, s390, sh4, mips), narrowing down some missing bits and
in overall I think it is on good shape. The only architectures I haven't
actually tested are csky, microblaze, nios2, and riscv.

Yes, the compat symbol is no longer needed, now that the loader no
longer requires matching sonames. I had forgotten about that; I will
prepare a patch as well.
I suppose it's better to send many small patches for these cleanups,
rather than one large patch.
Thanks,
Florian
