libolm - Implementation of the olm and megolm cryptographic ratchets

2016-09-01	Fix Ed25519 keypair generation	Richard van der Hoff
	Ed25519 private keys, it turns out, have 64 bytes, not 32. We were previously generating only 32 bytes (which is all that is required to generate the public key), and then using the public key as the upper 32 bytes when generating the per-message session key. This meant that everything appeared to work, but the security of the private key was severely compromised. By way of fixes: * Use the correct algorithm for generating the Ed25519 private key, and store all 512 bits of it. * Update the account pickle format and refuse to load the old format (since we should consider it compromised). * Bump the library version, and add a function to retrieve the library version, so that applications can verify that they are linked against a fixed version of the library. * Remove the curve25519_{sign, verify} functions which were unused and of dubious quality.
2016-05-24	Factor out pickle_encoding from olm.cpp	Richard van der Hoff
	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).
2016-05-24	Factor out olm_error_to_string to a separate file	Richard van der Hoff
	I want to be able to use this functionality from elsewhere, so factor it out to its own file.
2016-05-24	Rewrite _olm_cipher_aes_sha_256 initialisation	Richard van der Hoff
	Replace the init-static-var dance with some preprocessor macros
2016-05-23	Prefix for internal symbols	Richard van der Hoff
	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.
2016-05-23	Convert cipher.hh to plain C	Richard van der Hoff

2016-05-23	Convert error.hh to plain C	Richard van der Hoff

2016-05-23	Rename olm.hh to olm.h	Richard van der Hoff

2016-05-23	Complete fixes for olm_*_last_error	Richard van der Hoff
	Should have been in the previous commit :/
2016-05-23	fix range check in olm_*_last_errror	Richard van der Hoff

2016-05-16	Remove logging functionality	Richard van der Hoff
	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.
2016-05-16	translate logging.cpp to C	Richard van der Hoff

2016-04-26	Add a basic logging implementation	Richard van der Hoff
