Partial progress, but a major breakthrough in logging from the chroot

(Some tests are failing)
adding more chroot tests; still some broken
More chroot tests; some tests still broken/not implemented
add a logging test to cover work in the prior commit
Add a control flag for building the chroot

Specifically:
* Rename -c (DOPKGCHK) to -k (and cleaned up some old tests)
* Add DOCHROOT and -c
* Revamp the usage output
* Some tests are still failing
oops, more tests were broken than I thought
