e: full rewrite of our WBOD.

NOTE: the new behaviour require a parent process,
here enlightenment_start, to watch over enlightenment.
It does use ptrace to monitor his child and track
what is going on. When a crash happen it ask gdb to
add the backtrace directly into .xsession-errors.

If you use systemd user session, you may want to offload
that work to systemd. You can do so, but don't forget to
pass -nopause to enlightenment when you start it.

WARNING: For all user, you will need to exit your
current session and start a fresh one for this new WBOD
to work at all. Just restarting Enlightenment will not
help you.
