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.
