Richard van der Hoff d8b24acb77 PR feedback 
* write V1 pickles on the master branch
* the logging branch is going to write v0x80000001

Richard van der Hoff 8dd3c182ee 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.

Richard van der Hoff 757c422578 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.

Richard van der Hoff 708fddd747 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.

Richard van der Hoff fc4756ddf1 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.

Richard van der Hoff 444ef1f706 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.
