It would be useful to see what the stack looks like when we get
consecutive watchdog patting failures. We can then try to work out
what's ultimately causing this issue.
This change modifies vidforward to accept multiple RTMP URLs in
its control request handler. This allows for the creation of a
revid pipeline for a mac with multiple RTMP outputs.
This change adds functionality for broadcastManager state save.
This is done by marshalling the broadcastManager and saving to a
file. Loading is performed by unmarshalling an re-populating a
broadcastManager value. Testing has been added for this
functionality. Other functionality has been added a side effect.
