I looked about adding a return code for libssh2_keepalive_config for the
following two errors:
1) authorization not yet completed
2) want reply is not supported by the library
I found that the prototype is:
void libssh2_keepalive_config(LIBSSH2_SESSION *session,
As a result, making a change here would break the ABI in a
non-backward-compatible way (changing the void return to int...
How to proceed here?
