[mythtv] Ticket #2817: Unknown problem with socket communications causes segfault of backends

[Mark Buechler]

I added some code around line 804 of mainserver.cpp to spit out the
QStringList entries as well as "broadcast" and the backend runs fine to a
point then send RECORDING_LIST_CHANGE hundreds of times a second for several
seconds and eventually starts sending SCHEDULE_CHANGE as well. Eventually
DONE_RECORDING starts getting sent as well as LIVETV_CHAIN. So, looks like
to me there's a queue which isn't getting cleared.

- Mark.
