1b15465c42 Separate base64ing from the rest of msg encoding 
Factor the actual message encoding/decoding and encrypting/decrypting out to
separate functions from the top-level functions which do the base64-wrangling.

This is particularly helpful in the 'outbound' code-path where the offsets
required to allow room to base64-encode make the flow hard to see when it's all inline.

a919a149fb Update megolm_cipher as a global struct 
Initialise megolm_cipher via the preprocessor macro, instead of with a
function.

fa1e9446ac Use _olm_unset instead of memset 
memset is at risk of being optimised away, so use _olm_unset instead.

173cbe112c Avoid relying on uint -> int casting behaviour 
The behaviour when casting from a uint32_t which has overflowed (so has the top
bit set) to int32_t is implementation-defined, so let's avoid relying on it.

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.

8b1514c0a6 Implement functions to get the state of outbound session 
We need to be able to inspect an outbound session so that we can tell our peer
how to set up an inbound session.

42a300fc62 Factor out pickle_encoding from olm.cpp 
We don't need to have all of the top-level pickling functions in olm.cpp;
factor out the utilities to support it to pickle_encoding.cpp (and make sure
that they have plain-C bindings).

256bce10fc Factor out olm_error_to_string to a separate file

its own file.

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.

488567a45f Use a version script to restrict symbols in the .so 
We want to stop aes_* and sha_* functions leaking out of our .so, as well as
internal _olm_* symbols.

This also means we need to link the unit tests against the objects. Possibly we
should distinguish between unit tests and integration tests.

d4c8aae803 Add support for building the JS wrappers to the Makefile 
Now that we have C and C++, we need to split the compile and link steps
(because we need different flags for the C and C++ files), so this is
easier with a Makefile.
