1) Segfaults on closing localinput sources
   The streamer was being deleted before the trickplay module was stopped.

2) Segfaults on closing localinput sources #2
   The streamer must be deleted last -- as it deletes the tsprovider.

3) Hang on closing localinput sources
   The trickplay module was happily filling the C_SyncFifo to the
brim, and being blocked when it became full. Unfortunately, this
causes the tsstreamer to hang on shutdown as the consumer has been
stopped, but not the tsstreamer... I made it set m_bStop, wait for
a second, and Interrupt the tsstreamer thread in case it is stuck
in this situation.
