for page allocation instead of the static kmalloc memory.

...
Sysroot is now created with fakeroot. This allows root access to be
only needed for disk image creation, since it uses loopback devices.

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 :)
