pthread fix for bug 1002142 and 1002143
I made a patch for bug 1002142 and 1002143.
Basically this create a new state variable that track when you do a
sigwait/sigtimedwait/sigwaitinfo. When queuing a signal, it will wake the
target thread not only if the signal is unmasked, but also even if it's masked,
but the target thread is sleeping waiting for signals.
Also fix the EAGAIN and EINTR return codes for sigwait functions (POSIX
compliant).
And fixed the issue with crash when passing NULL info parameter to sigwaitinfo
and sigtimedwait. POSIX do allow to pass NULL info parameter.
So this is open for review :-)
