BitBake Shell
General Question to be decided: Make it a full-fledged Python Shell or
retain the simple command line interface like it is at the moment?
TODO:
* readline completion (file and provider?)
* specify tasks
* specify force
* command to reparse just one (or more) bbfile(s)
* automatic check if reparsing is necessary (inotify?)
* bb file wizard
BUGS:
* somehow the stamps or the make build cache gets confused.
Reproduce this by calling rebuild on a bbfile twice.
1st, some tasks are called twice (do_fetch for instance),
2nd, no tasks are called anymore on the second rebuild.
Obviously executeOneBB is corrupting some state variables
or making some bogus assumptions about state and/or control flow
