Bananymous 862993398d AOC2023: Implement day12
There seems to be a problem with my malloc so the hash map is not
working. This code worked fine on my linux with actually working
malloc :D

Bananymous 00d57d783e 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.

Bananymous 99a5b6e2ef AOC2023: Cleanup day9 code
Move tree building to its own function. Both parts can use the same
tree. This also decreaseas memory usage by one element by row :D

Bananymous abc69fa3d5 Bootloader: Search framebuffer information from kernel memory
Framebuffer information is no longer hard coded into bootloader.
Kernel can define framebuffer info structure in its memory which is
used for finding proper video mode.

Bananymous 8b01e2d4a2 Bootloader: Generalize framebuffer video mode search
Framebuffer size is now taken as arguments to vesa_find_video_mode

Heap sort is now more close to gnulibc++ version. This is just more
simplified version.

Bananymous b523ccb893 AOC2023: Implement day8
Second part was kinda weird. You are supposted to assume something
of the input, which necessarily is not true.

Bananymous 2e858fddb5 Kernel: Remove obsolete Scheduler::is_valid_tid()
This function was used when processes could die at any point in time.
Now that processes can only die in known spots, we can be sure they
are not holding any locks. This allows much more performant locking.
