[libvirt] [PATCH v3 1/4] m4: checking if ssh_session_is_known_server() exists.

[Julio Faracco]

This commit adds some checks inside libssh m4 checking to verify if
ssh_session_is_known_server function is available. This new function
scope replaces the old ssh_is_server_known() from libssh 0.8.0 and
below versions.

Another auxiliar enumerator was added to keep the compatibility with the
old standard used by ssh_is_server_known() function.
