Kill a whole bunch of unused code. I generated a list of dead functions by building with -ffunction-sections and linking with -Wl,--gc-sections -Wl,--print-gc-sections I kept a number of functions that seemed to be logical parts of an existing API, as well as stuff in varstubs.c, since that file is autogenerated.
