Comment (by Eschaton):

 I've looked at this and it appears it would be pretty straightforward to
 do with only three additional callbacks modeled after the recv/send
 callbacks:

 - A get_blocking callback to get the current blocking state of the socket
 in the couple places it's checked
 - A set_blocking callback to set the current blocking state of the socket
 in the couple places it's adjusted
 - A poll callback to be used by _libssh2_wait_socket() and possibly the
 deprecated libssh2_poll()

 With only those three callbacks, it should be possible to layer libssh2
 atop an arbitrary transport rather than specifically atop Berkeley
 sockets.
