The external cache API. Should the names include "optix" or be generic?

This lock caused me some trouble. ShadingSystemImpl::optimize_group grabs the same lock, and then calls serialize, so we deadlock without a change.
This is a quick fix, a recursive mutex would be another. I don't understand the locking scheme well enough to know the right call here.

Wasn't sure where to put these functions. They should be paired up, but one is used in llvm_instance and the other in shadingsys.
