Kernel: Ext2 filesystem now holds 10 preallocated block buffers
...
Inodes can query blocks from this buffer. This allows allocation of
blocks to not fail during normal operations. Also less stress on
kmalloc.

Kernel: Fix ext2 block allocation
...
Redo ext2 block allocation. This is now much "cleaner" although
I'm not too fond of the macros.

Kernel: VirtualRange doesn't store physical addresses of pages

This was unnecessarry allocation, since the page table allready
contains virtual address -> physical address mappings.

Kernel: Fully remove sys_alloc and sys_free
...
I could delete the whole FixedWidthAllocator as it was now obsolete.
GeneralAllocator is still used by kmalloc. Kmalloc cannot actually
use it since, GeneralAllocator depends on SpinLock and kmalloc runs
without interrupts.

Kernel/LibC: remove PATH resoltion from kernel
...
I have no idea why I had made PATH environment variable parsing
to be part of the kernel. Now the shell does the parsing and
environment syscall is no longer needed.

Kernel/LibC: add mmap for private anonymous mappings
