BAN: Add unstable version of hash map
...
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.

Weird thing is that memcpy optimized to infinite loop if I kept the

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...

LibC+userspace: Make everything compile with -Wall -Wextra -Werror
...
I added -Wall -Wextra -Werror as public compile flags to libc. Now
everything in userspace in compiled using these flags. I made all
necessary changes to allow compilation to work.
Only exception is execvp which has a large stack usage. Maybe it
should use malloc for the buffer but posix allows ENOMEM only when
kernel is out of memory... This can be fixed when fexecve is
implemented and there is no need for absolute path.
