Kernel: Make TID's be unique PID's

Browse source 
This is a little strange, but it's how I understand things should work.

The first thread in a new process now has TID == PID.
Additional threads subsequently spawned in that process all have unique
TID's generated by the PID allocator. TIDs are now globally unique.
