The pthread-based implementation is the generic one. Replacing
the stubs makes it clear that they do not have to be adjusted for
the libpthread move.
Result of:
git mv -f sysdeps/pthread/aio_misc.h sysdeps/generic/
git mv sysdeps/pthread/timer_routines.c sysdeps/htl/
git mv -f sysdeps/pthread/{aio,lio,timer}_*.c rt/
Followed by manual adjustment of the #include paths in
sysdeps/unix/sysv/linux/wordsize-64, and a move of the version
definitions formerly in sysdeps/pthread/Versions.
