e20c4ef0ef libc-cancellation.c cleanup. 
The unrelated function __libc_cleanup_routine should not be in
this file.  Move it into its own file.

cba0ca7925 Unify source for async cancel handling. 
Unify all three places where we enable async cancellation for
syscalls.  Optimize a bit.

9437b427ce Fix change to prevent cancel signal in unsafe places. 
The bits tested to decide when to delay the return when switching
off async cancel mode were wrong.  Fix that.  Also close a race
condition in pthread_cancel where the bit indicating the cancellation
is unconditionally set even if the cancel type might have changed.

1a7f254b4b No cancel signal in unsafe places. 
When disabling async cancellation we cannot return from the function
call if the thread is canceled.  This happens when the cancel bits
have been set before async cancel is disabled but the signal hasn't
been sent/received yet.  Delay for as long as necessary since
otherwise the signal might be received in an unsafe context.
