Implement the synchronization primitives like the Horizon kernel does (#97)

Browse source 
* Started to work in improving the sync primitives

* Some fixes

* Check that the mutex address matches before waking a waiting thread

* Add MutexOwner field to keep track of the thread owning the mutex, update wait list when priority changes, other tweaks

* Add new priority information to the log

* SvcSetThreadPriority should update just the WantedPriority
