- Added mutex_trylock() - Implemented most of exchange_registers() - thread_control() now needs a lock for operations that can modify thread context. - thread_start() does not initialise scheduler flags, now done in thread_create. TODO: - Fork/clone'ed threads should retain their context in tcb, not syscall stack. - exchange_registers() calls in userspace need cleaning up.
