Kernel: Remove TTY keyboard thread
...
This was really hacky as it had no idea when the keyboard had events
and the blocking was just one millisecond sleeps :D
Now keyboard device checks if current tty is receiving input and if so
it forwards the events to the TTY.

Kernel: Don't sync ext2 inode on read
...
This is the most common operation and we don't even update any fields
during read (although we should update atime). The disk read+write is a
bit too heavy with the current cache system

Instead of scanning the page table for free range, we not use the

Kernel: Changed stat values from func to be field
...
- Removed virtual functions for all of the stat stuff.
This did however introduce some issues, mainly with /proc
becoming out of sync if you changed your ID. I propose we
do the linux thing and just have a stat update function
which is optional, but allows dynamic updates of stat fields
for cases such as those in uid/gid in /proc.
- Simplified the API, although still kind of annoying
it is a bit simpler.
- Moved some of the FS structure from having the FS inode inside
the in memory inode to a Serialise <-> Deserialise model where
Inodes are deserialised from disk into in memory ones and then
back into on disk ones when it comes time for syncing.
This makes it semantically better in my opinion, as it explicitly
separates disk and non-disk functionality.

The old linked list allocator with power of two pool sizes was kinda
weird. Now we use 1MiB bitmap allocators for allocations <64KiB and
directly call mmap for larger allocations. This allows userspace to
actually free unused memory on `free` :)
