Message:
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.
