Adhemerval Zanella c6bb095eb5 nptl: Rewrite cancellation macros 
This patch changes the way cancellation entrypoints are defined to
instead call the macro SYSCALL_CANCEL.  An usual cnacellation definition
is defined as:

  if (SINGLE_THREAD_P)
    return INLINE_SYSCALL (syscall, NARGS, args...)

  int oldtype = LIBC_CANCEL_ASYNC ();

  return INLINE_SYSCALL (syscall, NARGS, args...)

  LIBC_CANCEL_RESET (oldtype);

And it is rewrited as just:

  SYSCALL_CANCEL (syscall, args...)

The idea is to remove LIBC_CANCEL_ASYNC/LIBC_CANCEL_RESET explicit
usage.

Tested on i386, x86_64, powerpc32, powerpc64le, arm, and aarch64.

	cancellable syscalls.
