splitmux: Implement new elements for splitting files at mux level. Implement 2 new elements - splitmuxsink and splitmuxsrc. splitmuxsink is a bin which wraps a muxer and takes 1 video stream, plus audio/subtitle streams, and starts a new file whenever necessary to avoid overrunning a threshold of either bytes or time. New files are started at a keyframe, and corresponding audio and subtitle streams are split at packet boundaries to match video GOP timestamps. splitmuxsrc is a corresponding source element which handles the splitmux:// URL and plays back all component files, reconstructing the original elementary streams as it goes.

/* GStreamer split muxer bin
splitmuxsink: add the ability to mux auxilliary video streams The primary video stream is used to select fragment cut points at keyframe boundaries. Auxilliary video streams may be broken up at any packet - so fragments may not start with a keyframe for those streams.

splitmux: Rewrite buffer collection and scheduling Majorly change the way that splitmuxsink collects incoming data and sends it to the output, so that it makes all decisions about when / where to split files on the input side. Use separate queues for each stream, so they can be grown individually and kept as small as possible. This removes raciness I observed where sometimes some data would end up put in a different output file over multiple runs with the same input. Also fixes hangs with input queues getting full and causing muxing to stall out.

splitmux: Implement new elements for splitting files at mux level. Implement 2 new elements - splitmuxsink and splitmuxsrc. splitmuxsink is a bin which wraps a muxer and takes 1 video stream, plus audio/subtitle streams, and starts a new file whenever necessary to avoid overrunning a threshold of either bytes or time. New files are started at a keyframe, and corresponding audio and subtitle streams are split at packet boundaries to match video GOP timestamps. splitmuxsrc is a corresponding source element which handles the splitmux:// URL and plays back all component files, reconstructing the original elementary streams as it goes.

splitmuxsink: Add new reset-muxer property With this the muxer is not set to NULL after each segment but instead only flush events are sent to it to reset the EOS state. As a result, the muxer will keep stream state and e.g. mpegtsmux will keep the packet continuity counter continuous between segments as needed by hlssink2. https://bugzilla.gnome.org/show_bug.cgi?id=794816

Revert "splitmuxsink: Use GstBin async-handling instead of our own." This reverts commit fa008f271a52f82dededc28bd81b020ca7939b47. async-handling in GstBin causes the pipeline to spin at 100% CPU as the top-level pipeline tries to change that state to PLAYING constantly. This is a workaround for a core problem, essentially, but an improvement in this case for now.
