16d9d29971 Kernel: Remove obsolete KeyboardLayout/
This was used by the old input system. Currently keyboard layout is
hardcoded to finnish. But it will be reworked as something read from
the filesystem

fa8e921ee8 Kernel: Rework the whole input system
We now use Device abstraction that will allow us to provide devices
to userspace through /dev. Currently Shell reads from first and only
device (it being PS/2 Keyboard).

814f0b215d Kernel: Create RecursiveSpinLock and add it to Process
We now lock every function within Proccess, just to be sure.
Recursive lock allows us to use lock from the same thread even if
we already have the spinlock locked

5fd26b4ea8 Kernel: Lock process functions instead of the ata controller
Process has to use locks at least on some functions so multithreaded
disk io is safe. This seemed to fix corrupted reads from disk

e5eab8bae4 Kernel: Ext2FS now does allocations better
We only have to allocate at the beginning of the all functions and
can properly exit before any disk reads if we run out of memory.

This makes development little bit 'harder' since the {read,write}_block
user must allocate a buffer of atleast block_size bytes.

I also made disk access to cause kernel panic on error since the error
handling during file write is something I don't want to think now.
The filesystem can easily corrupt so, I feel like when disk io starts
to fail I'll come back to this.

dbf7d9f19e Kernel: Ext2 directory functions now fail on invalid blocks
Invalid blocks should only happen while writing to a file and
I think in that case we should just bail out instead of giving
you incomlete inode list or search result.
