sp-flag related changes: sp-flag bit is set in DLNA.ORG_FLAGS only when the content is a strict live where s0=sN. The other live streaming scenario related to TimeShiftBuffering and In-progress recording sp-flag is not set.
sp-flag related changes: Connection stalling and background transfer mode bit is disabled in DLNA.ORG_FLAGS when enabling sp-flag for strict live where s0=sN. Connection stalling and Background transfer mode flags are set only when sp-flag bit is not set.
Fixed a bug in ODIDDataSource.preroll_mp4_resource(). TimeSeekRange response wasn't being added for npt=0- requests

The TSR response was created but not added to the response_list.

 DLNA flags and operation modes.

Fix for a crash seen at PlugFest 39 (CVP2RI-402)

The implementation of stop() for a mp4 container stream sets
 this.mp4_container_stream/mp4_container_source to null after stop.
 If/when the mp4 container push thread catches the exception from the
 stopped BufferGeneratingOutputStream, it can access the nulled
 variables causing an access violation, depending on which thread runs
 first.

Fixed the issue by extracting the container source name at the top of the
 container push thread function and putting it into a local variable.

Still need to retest the scenario with the vendor to validate the crash
 is fixed.
