Florian Weimer f47f1d91af nptl: Move pthread_create, thrd_create into libc
The symbols were moved using scripts/move-symbol-to-libc.py.

The libpthread placeholder symbols need some changes because some
symbol versions have gone away completely.  But
__errno_location@@GLIBC_2.0 still exists, so the GLIBC_2.0 version
is still there.

The internal __pthread_create symbol now points to the correct
function, so the sysdeps/nptl/thrd_create.c override is no longer
necessary.

There was an issue how the hidden alias of pthread_getattr_default_np
was defined, so this commit cleans up that aspects and removes the
GLIBC_PRIVATE export altogether.
