This commit removes everything not strictly necessary for running
"make clean all" inside jw-build.
packaging jw-devtest. This cuts the repo down from 24077 to 4725
lines of code.
The idea is to
1) Further remove bloat from the remaining bits
2) Re-add what's necessary to build and package other essential repos.
The decision should be based on whether or not jw-build can also be
useful in a non-janware context.
