Modified Files:
        src/lib/libpthread: pthread.c

Log Message:
Change the behavior of pthread_equal()

On error when not aborting, do not return EINVAL as it has a side effect
of being interpreted as matching threads. For invalid threads return
unmatched.

Check pthreads for NULL, before accessing pt_magic field. This avoids
faults on comparision with a NULL pointer.

This behavior is in the scope of UB, but should be easier to deal with
buggy software.
