First steps for making ptrace work with rthreads:
- move the P_TRACED and P_INEXEC flags, and p_oppid, p_ptmask, and
p_ptstat member from struct proc to struct process
- sort the PT_* requests into those that take a PID vs those that
can also take a TID
- stub in PT_GET_THREAD_FIRST and PT_GET_THREAD_NEXT
