rename a test, tweak the backlog
First pbulk bootstrap test

It's WAY too slow
Major test and prod refactorings

Mostly for performance, but also to make new testing possible.

This also enables running the tests without actually having the script
do the chroot step (or the sandbox).

Also started adding tests for the new "INSTPBULK" step.

Also eliminated a redundant test.

Turned on 'set -e' again.
