4af3879c26 Wrap __builtin_expect in pthread.h 
[BZ #14188]
This fixes compilation of programs using pthread_cleanup_push built
with non-gcc compilers and older gcc compilers.

9c6ea9facb Fix stack size and address inconsistency due to executable stack 
When a stack is marked executable due to loading a DSO that requires
an executable stack, the logic tends to leave out a portion of stack
after the first frame, thus causing a difference in the value returned
by pthread_getattr_np before and after the stack is marked
executable. It ought to be possible to fix this by marking the rest of
the stack as executable too, but in the interest of marking as less of
the stack as executable as possible, the path this fix takes is to
make pthread_getattr_np also look at the first frame as the underflow
end of the stack and compute size and stack top accordingly.

The above happens only for the main process stack. NPTL thread stacks
are not affected by this change.

439bf404b8 Allow a single-threaded program to cancel itself 
There is nothing in the POSIX specification to disallow a
single-threaded program from cancelling itself, so we forcibly enable
multiple_threads to allow the next available cancellation point in the
thread to run.

Also added additional tests to cover various cancellation scenarios.
