Bananymous 40b626b0aa Kernel: Rewrite all kernel mutexes 
Now SpinLock is actually just a spin lock and I added a Mutex that
does the same as the old "SpinLock". This is in preparation for
starting to support smp and making the kernel smp safe. This commit
also removes obsolete PageTableScope and CriticalScope which should
now be used by alternative APIs.

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.
