Adds a bus watch to the default main context with the given priority (e.g.
G_PRIORITY_DEFAULT). It is also possible to use a non-default main
context set up using glib.main_context.MainContext.pushThreadDefault (before
one had to create a bus watch source and attach it to the desired main
context 'manually').
This function is used to receive asynchronous messages in the main loop.
There can only be a single bus watch per bus, you must remove it before you
can set a new one.
The bus watch will only work if a #GMainLoop is being run.
When func is called, the message belongs to the caller; if you want to
keep a copy of it, call gst_message_ref() before leaving func.
The watch can be removed using gst.bus.Bus.removeWatch or by returning false
from func. If the watch was added to the default main context it is also
possible to remove the watch using glib.source.Source.remove.
The bus watch will take its own reference to the bus, so it is safe to unref
bus using gst.object.ObjectGst.unref after setting the bus watch.
