pulsesink: Re-enable stream status messages
Submitted by Arun Raghavan
+++ This bug was initially created as a clone of Bug 736071 +++
We've disabled stream status messages for now, as noted in the original bug. The real fix for this is to introduce PA API to allow callbacks in the threaded mainloop that can be executed without the mainloop lock held. Once such API is available, we should hook up the status callbacks into that mechanism so gst_element_post_message() can be called without the mainloop lock held (preventing a locking order mismatch with other callers between the mainloop and object lock).
