[libvirt] [PATCH v3 3/4] m4: checking if ssh_session_update_known_hosts() exists.

[Julio Faracco]

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