Bootloader: Add support for ext2 blocks up to 4 KiB
...
This should work with blocks bigger than that, but my linux system
only supports up to 4 KiB, so I cannot test this.
This allows getting rid of forced block size in mkfs and let the
program select appropriately sized blocks.

Bootloader: Fix bootloader on bochs
...
Bochs int 0x10 seems to scrap full ebp and top bits in some
registers. I now save all 32-bit registers on call frame. Also
ebp is across all int 0x10 calls.

Kernel: Implement supplementary groups
...
This code has very ugly file parsing code. I have to create API
for reading files line by line in kernel space...
This allows users to open framebuffer/input files without root.
Mounting has to be moved to userspace soon. It makes no sense to
hard code permissions for every (device) file.
