The in-process backend uses 'innernet', which is a net.Listener and
net.Conn implementation using in-process buffers instead of real
sockets.
Out-of-process backends can be used with the '-backend' parameter. An
additional flag is required to allow connections to non-localhost TCP
backends.
It's now possible to regenerate the protobuf files by calling 'go
generate' in rpc/. You will need protoc and protoc-gen-go in PATH.
This is only necessary after changing the protobuf definitions.
Improved parts of the conversation implementation, moved the
conversation event monitor to Identity, added event monitor
population, and other minor changes.
Refactor the connection management on contacts to have a goroutine
responsible for tracking the state of a contact's connection, launching
and canceling outbound attempts when appropriate, etc.
UNKNOWN is the new default status for contacts. A contact is in the
UNKNOWN state when we're not sure whether they are available or not, and
is in the OFFLINE state when we believe that we're online but attempts
to connect to that contact have failed.
A race would cause a call to AddOnionPorts that was blocked waiting for
a control connection to try to publish the service twice, because the
onion republication wasn't done until after the connection status
change.
This is fixed by refactoring the control connection setup to do all
setup before signalling the state change, including copying the list of
onions to publish. The code is slightly cleaner now as well.
Also, slightly refactor Ricochet to be an interface to get the various
top-level components, and let the implementation define it (such as
backend's RicochetCore RPC type)
