It's controlled by the new Sandbox argument.  Right now, it's rather
coarse-grained, it's Linux-only, and it may break some features.

This implements "algorithm 1" from my discussion of bug #9072: on OOM,
find the circuits with the longest queues, and kill them.  It's also a
fix for #9063 -- without the side-effects of bug #9072.

The memory bounds aren't perfect here, and you need to be sure to
allow some slack for the rest of Tor's usage.

This isn't a perfect fix; the rest of the solutions I describe on
codeable.

This lets us have the possibility of fine-tuning the check in the tor_sscanf test cases at a later date.
