Add support for pthread_{get|set}concurrency support.
NuttX uses 1:1 threading model (every pthread is a kernel-managed thread),
so this function has no real effect on the scheduling behavior.

Add support for sigsetjmp() and siglongjmp().
This implementation is build on top of setjmp() and longjmp().
sigsetjmp() in that case must be implemented as a macro otherwise
we lose setjmp context.
siglongjmp() is kept as inline function to satisfy the PSE52 VSX
tests requirement.
An alternative implementation requires writing these function in
assembly code for each architecture.

This commit adds simple implementation of guardsize for pthreads.
At this moment this option simply increases the size of allocated pthread stack.
At default pthread guard size is set to 0.
