9beb6330c0 simplify cancellation point handling 
we take advantage of the fact that unless self->cancelpt is 1,
cancellation cannot happen. so just increment it by 2 to temporarily
block cancellation. this drops pthread_create.o well under 1k.

729cb49f52 new framework to inhibit thread cancellation when needed 
with these small changes, libc functions which need to call functions
which are cancellation points, but which themselves must not be
cancellation points, can use the CANCELPT_INHIBIT and CANCELPT_RESUME
macros to temporarily inhibit all cancellation.
