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
I want to be able to use this functionality from elsewhere, so factor it out to
its own file.

d4a3c8dbaa Remove 'destruct' from cipher_ops
We never delete a cipher, and the destruct op is empty, so it's a bit pointless

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.

3965320a9c Remove logging functionality
Concerns have been raised that including logging functionality makes it harder
to audit the implementation to ensure that no secret information is leaked. We
are therefore removing it from the master branch.
