SWIM needs encryption because it transmits packets affecting cluster state and
topology, probably via public networks between datacenters. Tarantool hasn't had
normal crypto library with useful C API on board until now. OpenSSL was used,
but its API is crazy, and before this patchset it was used in Lua only, via FFI.
The patchset moves existing OpenSSL wrappers into a separate library and extends
it with pretty API. It is going to be used by SWIM.
Branch: http://github.com/tarantool/tarantool/tree/gerold103/crypto-lib
Changes in V2:
- Added new codec 'None';
- Renamed 'encode/decode' to 'encrypt/decrypt';
- Removed usage of constants from crypto.c.
V1:
