Kernel: Now all active processors are used in scheduling
...
When a timer reschedule happens, ipi is broadcasted too all
processors for them to perform a reschedule!

Kernel: Rewrite scheduler thread lists
...
Scheduler now has its own data SchedulerQueue which holds active nad
blocking thread lists. This removes need for BAN/Errors.h and making
current thread separate element instead of iterator into linked list.
This makes it possible to have current_thread on each processor
instead of a global one in Scheduler.

Kernel: Per processor information is now stored in class Processor

This allows us to allocate processor stacks, and other per processor

ap_trampoline feels super hacky, but it works for now.
