Extend ssh_options_get() to support more options, Add Windows DLL versioning
Extends ssh_options_get() to support more options: SSH_OPTIONS_KEY_EXCHANGE, SSH_OPTIONS_HOSTKEYS, SSH_OPTIONS_PUBLICKEY_ACCEPTED_TYPES, SSH_OPTIONS_CIPHERS_C_S, SSH_OPTIONS_CIPHERS_S_C, SSH_OPTIONS_HMAC_C_S, SSH_OPTIONS_HMAC_S_C
