Bananymous 1de9daa40f Kernel: Move interrupt status stuff to Processor.h 
SpinLocks are now locked with processor id instead of thread id. This
allows having multiple processors running while scheduler is not yet
activated.

Bananymous a667d88f93 Kernel: Remove now obsolete CriticalScope 
All critical scopes in kernel are now replaced by SpinLocks. This
allows proper locking in actual multiprocessing with multiple cores.

Bananymous 6d59a2b45d Kernel: Remove VirtualRanges created in kmalloc memory 
These were only used as stacks of kernel threads, but they can just
as well be allocated as full pages from Heap

Bananymous f73e954b28 Kernel: Remove SpinLock from Pipe 
Pipe already is using lock on the inode. If you read from pipe when
there was no data, pipe blocked indefinately since writes were blocked
by Inode::m_lock.
