+ Skip cow for now, maybe implement later but try to keep things simple.

The output is close enough, and I like that uncrustify is a third-party
tool, so people can install a single tool for formatting instead of
having to lug around a whole toolchain. I fully expect to have to add
settings to uncrustify.conf, but let's see how this goes.

+ Next step, start documenting contents of each file.
|
|
+ next up would probably be to start working on process/thread
relationships, largely as documented. Still not entirely sure about
how I want to handle fork, but I suppose I might figure it out at some
point.

+ Should document this better but essentially a server requests a shared
buffer, and chan then share this buffer to a thread. Freeing the
buffer is done through normal means. MR_SHARED is used for buffers
that are shared, and MR_OWNED tells whoever is freeing that region
that it is allowed to free the physical memory behind the shared
buffer.

+ Mainly just moving stuff out or arch/riscv/ that should be handled in
common/
+ Prepared separate process stack/call stack for server callbacks, rest
to be implemeted soon ish

+ Lots of bughunting to do, probably lots of off-by-one and so on
errors, and I make a lot of naive and possibly dangerous assumptions.
But cool start nonetheless. Should also come up with some method of
exchanging data between the init and actual kernel, probably some struct
of some sort. TODO
|
|
+ Added new common/ directory, into which code that should be shared
with init and kernel is to be added. Currently string.c and bytes.c.
Code in common/ should be marked with __weak, so as to allow the arch to
implement a better, more optimised version of the function if
possible/required.
+ Created include/apos/types.h with macros essentially providing the
libc limits.h and stdint.h. At the moment I use gcc/clang predefined
macros for most things.
