Bananymous 76f48f095c Kernel: Rewrite a lot of ext2 code 
This commit consists of multiple big changes

1. blocks for inodes are now allocated on demand
  - reading from non allocated block will just return zeroes
  - writing to non allocated block allocates it

2. code doesn't really use raw pointers anymore
  - all casts to uint32_t or structures are now replaced with
    spans. either as<T> or as_span<T> which both are bounds
	checked

3. code doesn't depend on random macros for accessing indirect blocks
  - i added some recursive functions which take care of this :)

Bananymous b7007016c0 BAN: Implement Ext2 file unlinking 
Ext2 inodes can now be unlinked from directories and after last
inode closes (destructor gets called) we check if link count is 0
and cleanup the inode from filesystem

Bananymous f3d9da9549 Kernel: Rewrite all read/write functions to use BAN::ByteSpan 
This allows us to not work with raw pointers and use sized containers
for reading and writing.

Bananymous 669b2ace4e 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.

Bananymous 0e67c6318b Kernel: Fix ext2 block allocation 
Redo ext2 block allocation. This is now much "cleaner" although
I'm not too fond of the macros.
