bitbake: server/process: Add bitbake-server and exec() a new server process
Trying to have a new python process forked off an original doesn't work
out well and ends up having race issues. To avoid this, exec() a new
bitbake server process. This starts with a fresh python interpreter
and resolves various atexit and other multiprocessing issues once
and for all.
