use less reflection in command line method invocation
Add initial init scripts library, including systemd, sysvinit, upstart, and openrc
Update hack/release.sh process to automatically invoke hack/make.sh and bail on building/testing issues
Work around an exotic bug affecting Docker-in-Docker + systemd.
Remove spurious messages, and use proper args expansion.

Also, display some (hopefully helpful) message when no command was given.
Change bundle order, and fix shell array expansion.

I believe that it is helpful to build the binary first. That way,
if you interrupt the tests, you still get a binary to play with.
If you run the tests first and interrupt them, no binary for you!

Also, the second part of this commit is an undeniable proof that
Bash array syntax is nothing else than an elaborate troll by Bash
authors.

mkimage-debootstrap.sh: Add -p option to invoke debootstrap with http_proxy.
