Now modifying Scheduler.h or Thread.h doesnt trigger practically a full
kernel rebuild. This required moving Mutex and RWLock of of line but
that should be fine :^)
Kernel now makes sure thread is not holding any spinlocks when it tries
to lock a mutex or yield. Spinlocks are supposed to be only used for
short times without the possibility of yielding
This allows us to allocate processor stacks, and other per processor
structures dynamically in runtime. Giving processor stack to
ap_trampoline feels super hacky, but it works for now.
