Bananymous 7ee4ecd7f4 BAN: Vector's and Queue's underlying type is T* instead of uint8_t*
I have no idea what kind of brainfart I had to make use uint8_t*
that just complicated the code :D

Bananymous 338771c5b0 BAN: Cleanup Vector code
*Applies to last patch also!*

Remove duplicate code in iterators. We used to have separate iterator
and const_iterator but now they are the same class with some enable_if
magic to disable references from const_iterator

This introduces some 'bad things' you can for example call
const_iterator.operator*<false>() to obtain non const reference. I
don't think this matters since you could use const_cast or something
else to work around const if you really tried

Bananymous 0eb1fb8bae Buildsystem: Build disk image manually
We don't use grub-mkrescue anymore. Instead we build the disk image
manually. This allows us to have known disk layout for easier testing
when I get to implementing disk reading. For now I made the root
partition ext2 since I think that will be the first format that I'll
implement.

Bananymous cdbad56ed7 Kernel: Update shell thread command to run following command as thread
'thread echo "Hello World"' runs the command 'echo "Hello World"' after
5 seconds have passed. This was just my test code for threading

Bananymous 5b5e620d8a Kernel: Improve multithreading support
We can now use arbitary BAN::function<void(...)> as the Thread.
I also implemented multithreading for i386 since it was not done
on the initial multithreading commit.

Bananymous 117d1de038 Kernel: panic does not need to include <kernel/kprint.h>

Bananymous 9b8de5025a All: rename every function from UpperCamelCase to snake_case
This was a mess since I didn't know which to use but now I decided
to go with snake_case :)

Bananymous 6a9d60a8fb Kernel: Implement somewhat functioning multithread support
This still uses only a single cpu, but we can now have 'parallelization'

This seems to work fine in qemu and bochs, but my own computer did not
like this when I last tried.

I have absolutely no idea how multithreading should actually be
implmemented and I just thought and implemented the most simple one I
could think of. This might not be in any way correct :D
