Subject: [PATCH] api: disallow virDomainAgentSetResponseTimeout() on read-only
 connections

This function changes the amount of time that libvirt waits for a
response from the guest agent for all guest agent commands. Since this
is a configuration change, it should not be allowed on read-only
connections.
