Introduce informational VRF tags on allocations to match uncomitted patch
in production.
Also add a minor main.cgi error-log-cleanup hack around deleting routed
blocks and master blocks instead of bending getBlockData() out of shape
only to have to put it back when the database structure changes get merged.
