b482321213 Pass in a buffer to olm_session_describe
instead of having a static one, as that could end up taking up a
lot of memory if your app keeps olm sessions hanging about.

39a1ee0b18 Add olm_session_describe
As a way to dump the state of an olm session, ie. the chain indicies,
so we can debug why olm sessions break and get out of sync.

b83a0c0992 Fix comment and also js build
The python that searches the header files for exports isn't smart
enough to know what is a comment and what isn't, so it picks this
up too and emscripten then complains about it being undefined.

0346145a81 Work with PkDecryption keys by their private keys
Change interface to allow the app to get the private part of the
key and instantiate a decryption object from just the private part
of the key.

Changes the function generating a key from random bytes to be
initialising a key with a private key (because it's exactly the
same thing). Exports & imports private key parts as ArrayBuffer at
JS level rather than base64 assuming we are moving that way in
general.

All the other methods clear their random inputs. This one needs to do the same,
to reduce the risk of the randomness being used elsewhere and leaking key info.

2fc83aa9ac Sign megolm messages
Add ed25519 keys to the inbound and outbound sessions, and use them to sign and
verify megolm messages.

We just stuff the ed25519 public key in alongside the megolm session key (and
add a version byte), to save adding more boilerplate to the JS/python/etc
layers.

39212987bd Create new constants for key lengths, etc
We were using olm::KEY_LENGTH for everything under the sun which happened to be
32 bytes long, and making a bunch of assumptions in the process. Create a bunch
of new constants (as C #defines rather than C++ consts so that I can use them
in another forthcoming refactor).
