[0/8] nptl: Move pthread_detach and pthread_join into libc

  This needs a few cleanups first, and the series also moves the remaining
stack cache management into libc (reducing the size of
nptl/allocatestack.c as a side effect).

Tested on i686-linux-gnu and x86_64-linux-gnu, built with
build-many-glibcs.py.  (I had to revert the 32-bit incompatible warning
patches.)

Florian Weimer (8):
  nptl: Remove unused nptl/pthread_sigqueue.c stub implementation
  nptl: Move pthread_sigqueue implementation into main nptl directory
  nptl: Remove always-disabled debugging support
  nptl: Move pthread_setattr_default_np into libc
  nptl: Move stack cache management, __libpthread_freeres into libc
  nptl: Move __free_tcb into libc
  nptl: Move pthread_detach, thrd_detach into libc
  nptl: Move thread join functions into libc
