Kernel: Don't crash the kernel if ext2 encounters disk error
...
This will most likely result in a corrupted filesystem, but crashing the
kernel is too much :D

Kernel/LibC: Rework dirent structure
...
dirent now contains statically sized d_name. This allows using
sizeof on the name and dirent properly, which some programs seem
to be using.

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 :)

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

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.

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.
