persistent nock caching

[matthew-levan]

Implements UIP-0103 for Ares. See https://github.com/urbit/vere/pull/508 for more. This PR depends on #143 to fix the "double jamming" problem, and also for an interface by which to implement cache reclamation/eviction for the persistent cache (keep).

Resolves #148.

@matthew-levan aside from the PMA what does this need? We discussed eviction strategies, what is done in vere?

Schmitt algorithm is implemented, see here: https://github.com/urbit/vere/pull/549

I still need to test this too-- a couple bugs from earlier this week prevented me from booting and testing when I was writing this.

in vere, the underlying HAMT is also capped, with CLOCK eviction.
