Kernel: Add fast page to page table
...
Add "fast page" to KERNEL_OFFSET. This is always present in page
tables and only requires changing the page table entry to map. This
requires no interrupts since it should only be for very operations
like memcpy.
I used to map all temporary mappings to vaddr 0, but this is much
better. C++ standard always says that nullptr access is undefined
and this gets rid of it.
Fixed some bugs I found along the way

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 :)

be optimized but the main slow down is probably the whole disk
structure in the os.
AHCI drive is now the default when running qemu.
