Lorenz Bauer	c57c793909	unix: add SIG_BLOCK and friends for Linux ... The recently added PthreadSigmask syscall expects a parameter how that specifies which action to perform on the thread's signal set. The value of this parameter differs between arches. Add the SIG_* constants to have a portable source.

Lorenz Bauer	d9d178bc13	unix: add PthreadSigmask for Linux ... Add a syscall wrapper for SYS_RT_SIGPROCMASK and export it as PthreadSigmask. The latter is defined by POSIX and can therefore be implemented by Darwin, etc. later on. Follow the approach used by Signalfd of passing _C__NSIG/8 as sigsetsize. This avoids exporting _C__NSIG and allows the syscall to work with the current definition of Sigset_t, which doesn't match the kernel definition of Sigset_t.
