ec4922395b Fix check for PI mutex in x86-64 pthread_cond_signal

421665c40a Optimize x86-64 syscall cancellation handling. 
The syscall wrappers had to save and restore the syscall parameter
values and return value when calling the functions to enable/disable
cancellation were called.  Not anymore.  The called functions are
special and don't modify any unexpected registers.

Ulrich Drepper
42e69bcf11 Support requeueing for condvars using PI mutex. x86-64 only. 
Add support for the new FUTEX_WAIT_REQUEUE_PI and FUTEX_CMP_REQUEUE_PI
options of futex.

515a8908ce Make x86-64 pthread_cond_timedwait more robust. 
It just happens that __pthread_enable_asynccancel doesn't modify the $rdi
register.  But this isn't guaranteed.  Hence we reload the register after
the calls.

exception handling functionality of the gcc runtime.

bfdb73e145 Implement pthread_sigqueue. 
The kernel from 2.3.31 on supports the rt_tgsigqueueinfo syscall.
Use it to implement the non-standard extension which, like
sigqueue, can pass additional data to the receiving thread.
