No. RFC 4254 chapter 5 describes SSH channels. They are just multiplexed
byte streams within one SSH connection, described by RFC 4254.

Also no.
Both of these constructs are not very widely portable, so they're a poor
fit for a cross-platform library such as libssh2.

Well, every SSH connection runs over one TCP socket, and I think it
would be possible for libssh2 to assist applications in I/O handling
but noone has done it. At a minimum it requires a new state machine
in libssh2, but getting it all done neatly would probably require
rewriting much of libssh2...
