869de7283f Kernel: MMU::get() is now MMU::kernel
MMU is can now be locked with RecursiveSpinLock.

Scheduler now has get_current_tid() that works before the Scheduler
is initialized. This allows RecursiveSpinLock usage early on.

faf14b880e LibC: Rewrite all the headers.
We now have more or less posix issue 2018 conforming libc headers.

This was a really time consuming and boring operation but it had to
be done.

Now we get to actually start implementing libc :)

cae0a1cc60 LibC: add working f modifier to printf
This is implementation will write out of bounds if the conversion
takes more than 1024 characters (either super large number or very
big percision).

Also we dont handle NaN and infinity cases

49fe3d0d4f LibC: add probably functional *printf
I wrote a general printf function that takes an putc function
pointer. We can use this to implement all the printf family
functions. I haven't done thorough testing with this, but it seems
to be functional for the most part

ff2e2937a5 Kernel: Remove offset from OpenFileDescriptor
This is now handled on the libc side. There might be reasons to
have it in kernel side, but for simplicity's sake I'm moving it
to libc for now :)

f1667b398a Kernel: FixedWidthAllocator operates on MMU

b0ec0f1a1a Kernel: We add FixedWidthAllocators on demand
On SYS_ALLOC we will add a new FixedWidthAllocator if the old ones
are already full or we don't have one with proper size. This allows
arbitary number of allocations as long as you have enough memory
available :)

Next I will be writing a general allocator for allocations larger
than 4096 bytes which should make SYS_ALLOC syscall complete :)
