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 :)

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 07f8c972b3 Shell: Set get old termios earlier
I sourced the config file before getting old termios. Sourcing
updated the termios so old_termios was always in non canonical, non
echoing mode.

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 71cad2fc38 BAN: Implement ByteSpan
This is a span over exisiting containers/data types. I'm not too
happy with the constructors and assignment operators, but they will
work for now

Bananymous c17cdb39d5 Kernel: Map multiboot2 memory in PageTable initialization
It cannot be assumed that multiboot data lies between kernel_end
and 2 GiB mark, so I properly allocate virtual address space for it.

This allows better compatibility with (U)EFI and gives RSDP location
instead of me having to scan ram to find it.

Bananymous c4a640bcb6 Kernel: Fix ATADevice naming
ATADevice now stores its name instead of using static buffer. Old
static buffer was changing on every name query. I just hadn't noticed
since virtual machine disks were always sda.
