mm: fix page frame allocator bugs
This also includes a minor refactor of everything,
as well as some optimizations.  The bitmap
operations have been moved into a separate file
because they are probably gonna come in handy in
other parts of the system as well.

kmalloc: add shiny new buddy page frame allocator
This is still kind of a work in progress because
it will be the backend to a slab allocator, which
in turn is managed by kmalloc().

x86/mm: add huge page support
This is part of a series of commits where i
completely rewrite kmalloc() because it needs to
be able to return physically contiguous memory for
DMA operations.
Yes, i know the build isn't working right now.

clist: you got to be fucking kidding me
This was my actual intention behind the previous
commit.  I should really go to bed.

libc: refactor a couple of string routines
This is just a minor overhaul of several utility
functions, in part because it kept bothering me
and in part because i was bored.

kprintf: implement "full" format sequence support
So this was painful.  kprintf() supports most of
the format specifiers from BSD now, except for the
$ sequence.  It has gotten a general overhaul and
is significantly more sophisticated, bloated and
slower now.  There is also some minor stuff i
forgot about, like the 't' length modifier, but
that isn't so important right now and will be
fixed later(TM).

kmalloc: add actual memory allocator
Now that memory allocation finally kind of works,
we can finally start focusing on the core system
architecture.  This commit also fixes some bugs in
get_page() and friends, as well as performance
improvements because the page map is addressed as
unsigned longs rather than individual bytes.

kprintf: fix vararg bug
Turns out you can't pass a va_list to subroutines
as per the C standard, even though it worked
perfectly fine on ARM.  Well then, the entire
kprintf thing needs to be refactored anyway at
some point in the future, so that more formatting
options are supported.
