Towards adding sys_clone()

Browse Source 
Stopped working on self_spawn() - going to finish clone() syscall first.
Arch-specific clone() library call that does ipc() and cloned child setup.
- Need to finish thread_create() that satisfy clone() necessities. i.e. setting up its stack.
  Question: Does the pager (and thus the microkernel) have to explicitly set SP_USR?
  Once the call is known to be successful, the library could set it.
