Make space in the session pickle for chain index
...
Keeping track of the chain index is a useful thing to do, but is only required
if we've enabled diagnostics. Extend the session pickle format to make a space
for it, so that pickles can be transferred between the logging_enabled branch
and the master branch without loss of information.
Also add some tests for session pickling which explicitly check that we can
unpickle both formats of pickle.

Remove unused 'chain_index' from Ratchet
...
This was introduced when I was experimenting with support for logging progress
in Olm. That is now relegated to the logging_enabled branch, so this should
probably be removed.
This also fixes the incompatibility of session pickles from the current master
branch with those from olm 0.1.0.

Remove session_id from group messages
...
Putting the session_id inside the packed message body makes it hard to extract
so that we can decide which session to use. We don't think there is any
advantage to having thes sesion_id protected by the HMACs, so we're going to
move it to the JSON framing.

Fix up some names, and protobuf tags
...
Make names (of session_key and message_index) more consistent.
Use our own protobuf tags rather than trying to piggyback on the one-to-one
structure.

Prefix for internal symbols

Give a load of internal symbols "_olm_" prefixes. This better delineates the
public and private interfaces in the module, and helps avoid internal symbols
leaking out and possibly being abused.
