Richard van der Hoff 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.

Richard van der Hoff 2fd28a6682 Rewrite _olm_cipher_aes_sha_256 initialisation
Replace the init-static-var dance with some preprocessor macros

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

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.

Richard van der Hoff acae4e8438 Remove functions which return strings
We don't want anything which does dynamic memory allocation in the library.

Richard van der Hoff 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.

Richard van der Hoff 25953b350b Use header files where possible
This fixes an incorrect re-declaration of ed25519_sign.

Implement header files for some of the other library bits so that we don't need
to declare functions in crypto.cpp.
