There is some confusion in the different branches on what the minors
mean. We expect minor == 2 to mean support for
SPICE_MSG_MAIN_MIGRATE_SWITCH_HOST and SpiceMsgMainMigrationBegin
with added public key info. All other additions like tunneling are
for minor 3 (although we might not do a release with minor 3, but
rather the bump major).
