Kernel: Move ATADevice to its own file from ATAController
...
The API is kinda weird since device reads/writes go from
ATADevice -> ATAController -> ATADevice
but this is for now atleast necessary since ATAController has(?)
to keep all devices from using the disks at the same time

BuildSystem: We are now using cmake instead of plain make

I have been annoyed for a while since I had to build everything
when running the os since the buildsystem was really bad.
I wanted to rewrite the whole build system and changed to using cmake

Kernel: Improve locking in Process, VFS and ATAController
...
We used to block on all process access. This meant that shell
reading the keyboard input would block all VFS access making disk
accesses practically impossible. We now block only when it is
necessary :)

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.

Invalid blocks should only happen while writing to a file and
