lib/common.sh: Make it safe to include multiple times.
This is similar to common C #ifdef guards.
I was tempted to wrap the entire thing in the if/fi (rather than use
'return' to bail early. However, that means it won't execute anything
until after it reaches 'fi'. And if `shopt -s extglob` isn't executed
before parsing, then it will syntax-error on the extended globs. One
solution would have been to move `shopt -s extglob` up above the
include-guard. But the committed solution is all-around simpler.
