* Drop remaining sleep() logic in favor of polling * Use best guess delivery system if none is set * Make tuning/locking timeout configurable * Add signals for tuning start, done and fail * Drop gst_dvbsrc_frontend_status(). It was used only for signal LOCK checking. This is now part of the tuning/locking loop * Break up frontend configuration and tuning on separate functions Plus: * Add some more useful DEBUG/TRACE messages * Move over misplaced DVB API message * Fix wrong comment for default DVB buffer size (http://linuxtv.org/downloads/v4l-dvb-apis/dmx_fcalls.html#DMX_SET_BUFFER_SIZE) This patch builds up on previous work done by Fabrizio (Misto) Milo <mistobaan@gmail.com> https://bugzilla.gnome.org/show_bug.cgi?id=641204
