Panic on non-actionable failures

This is based on Michael's comments on aosp/2280849. For methods which
should never fail unless the VM is already dying, and for which
clients cannot take any meaningful action, panic instead of returning
false. Make sure we log the cause first.

Update client code to match. Update doc comments in the header file.

Also clarify that calling notify read more than once is harmless
(otherwise it would panic).

Incidentally, rename vs_payload_service.rs because it was confusing me
(we have a file of the same name in microdroid manager which actually
implements the service.)

Changes to AVmPayload_runVsockRpcServer will come later.
