Implement a helper library for POSIX semantics syscalls.
Since Linux kernel supported threads are not POSIX threads
and the glibc pthread library only supports POSIX semantics
for 9 system calls, to fully support the POSIX semantics for
a process sharing its security state across all of its
threads, we've created libpsx.
This commit also includes a threading test in tests/ for
this new psx_syscall() abstraction - one that transparently
mirrors calling POSIX-needing semantics syscalls over
all running threads.
