barebones LRU crawler proof of concept

so many things undone... TODO is inline in items.c.

this seems to work, and the locking should be correct. it is a background
thread so shouldn't cause significant latency. However it does quickly roll
through the entire LRU (and as of this PoC it just constantly runs), so there
will be cpu impact.
