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.

This version differs only when doing rebucket. If rebucket fails,
the whole hash map is invalidated. This allows rebucketing to use
moving instead of copying.

LibC: Optimize malloc by a lot

I now cache first free node in malloc_pool and whether the node is
last or not. There allow doing less full iterations over the whole
malloc pool.
Malloc is still unbearably slow and I will have to write a proper
fast malloc at some point. With this patch running aoc2023/day12 is
atleast possible. Probabaly will take closer to an hour...
