[0/7] nptl: Move barrier implemention into libc

  A minor complication is that the message queue implementation uses
barriers to communicate with its helper thread, but is still in
libpthread, so private exports had to be added.

Tested on i686-linux-gnu, powerpc64le-linux-gnu, x86_64-linux-gnu.
Built with build-many-glibcs.py.

I've pushed a rebase series to fw/libpthread-barrier.  (Not sure if
everybody is using the abilist merge driver I posted, it can handle such
conflicts automatically.)

Thanks,
