adaptivedemux: release the manifest lock ...

before broadcasting preroll.

The deadlock was as follows:

-> The subclass pushes a buffer on a newly-created stream in T1
-> We take the preroll lock in T1, to handle_preroll
-> The demuxer is stopped in T2, we take the MANIFEST_LOCK
-> T1 starts blocking because it received a reconfigure event
   and needs to take the MANIFEST_LOCK
-> T2 deadlocks because it now wants the preroll_lock.
