Kernel: Remove offset from OpenFileDescriptor
...
This is now handled on the libc side. There might be reasons to
have it in kernel side, but for simplicity's sake I'm moving it
to libc for now :)

Kernel: Add barebones GeneralAllocator for >4096B

Kernel: We add FixedWidthAllocators on demand
...
On SYS_ALLOC we will add a new FixedWidthAllocator if the old ones
are already full or we don't have one with proper size. This allows
arbitary number of allocations as long as you have enough memory
available :)
Next I will be writing a general allocator for allocations larger
than 4096 bytes which should make SYS_ALLOC syscall complete :)

Kernel/LibC: add free function for FixedWidthAllocator
...
I have to rework the syscall API and allocators in process. For
now this works well enough :)

Kernel: Add basic fixed width allocator for userspace
...
We have to move process stacks to the general heap and maybe map
kernel to higher half.
