First version that compiles with new file layout.

Had to make many changes to get it to compile across many files,
including removing the LOCAL specifier from almost all functions.
Edited the Makefile to compile all three files and link them.
Haven't tested on hardware yet, that's the next step.

Lots of small changes to avoid warnings, now that I have turned
-Wall on. This makes the code a bit "better".
