When the test suite is running, we don't want to be triggering the startup of daemons for the secondary drivers. Thus we must provide a way to set a custom connection for the secondary drivers, to override the default logic which opens a new connection. This will also be useful for code where we have a whole set of separate functions calls all needing the secret driver. Currently the connection to the secret driver is opened & closed many times in quick succession. This will allow us to pre-open a connection temporarily, improving the performance of startup.

There is a long standing hack to pass a virConnectPtr into the qemuMonitorStartCPUs method, so that when the text monitor prompts for a disk password, we can lookup virSecretPtr objects. This causes us to have to pass a virConnectPtr around through countless methods up the call chain....except some places don't have any virConnectPtr available so have always just passed NULL. We can finally fix this disastrous design by using virGetConnectSecret() to open a connection to the secret driver at time of use.

During domain startup there are many places where we need to acquire secrets. Currently code passes around a virConnectPtr, except in the places where we pass in NULL. So there are a few codepaths where ability to start guests using secrets will fail. Change to acquire a handle to the secret driver when needed.

It is very difficult while reading the migration code trying to understand whether a particular function is being called on the src side or the dst side, or either. Putting "Src" or "Dst" in the method names will make this much more obvious. "Any" is used in a few helpers which can be called from both sides. Signed-off-by: Daniel P.
