Implement core serial routines
...
This is just a rough baseline for the higher-level
serial handling code and will probably change
within the next couple of commits.

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).
