mm: make malloc and free system calls
...
This is required because the heap is shared among
all tasks and protected using a mutex which only
works in kernel space.

kiss capitalism goodbye for good
...
The CNPL will make sure that absolutely no corporation is going to get
anywhere near Ardix -- exactly as it should be. Fuck you, corporations!

piss off capitalism
...
Ardix is being relicensed to GPL v3 or later. I have no idea whether you
can just do this if you feel like it or if it has any consequences, but
i kinda don't really care that much about it. Any changes made after
this commit will definitely fall under the GPL though, and considering
that only few things are really working yet anyways this is good enough
for me.

Get rid of unnecessary if branch
...
Branching is slow compared to ALU operations and stuff, you know

Get rid of unnecessary loop counter
...
Incrementing counters in those loops are redundant
as we are keeping track of the ptr offsets anyways

Simplify ringbuf indexing
...
This whole pointer arithmetic things might be all
fancy and stuff, but the diff should make it clear
that it is just unnecessarily complicated.

Add ringbuf_size API
...
This might become useful if we want to dynamically
allocate an array that stores the entire queue.

Add ring buffer implementation
...
The next big step is to implement some sort of serial console in order
to get some debug output on real hardware (unfortunately, I don't have
a hardware debugger).
