cleanup and reformat bash syntax in 04 script

Cleanup and reforamt bash syntax in 04 script. Also requires fixes
to lib/common.sh, but to keep PR contained, I rather took out the
utility functions and put them in new lib/utils.sh.

Also, fixed some leftover issues I missed first time around in 01, 02
and 03 scripts for consistency.
