sample H264 byte-stream

+++ This bug was initially created as a clone of Bug #767232 +++

Since commit eb1ebf226ff8c29ea976169f81135219f1ab412b of gst-plugins-base the
decoder will emit GST_FIXME logs:

FIXME           videodecoder
gstvideodecoder.c:1057:gst_video_decoder_drain_out:<omxh264dec-omxh264dec0>
Sub-class should implement drain()

For every frame handled by the decoder.

The use-case is the following:

GST_DEBUG=3 gst-launch-1.0 filesrc location=raw.h264 ! "video/x-h264,
stream-format=(string)byte-stream, alignment=(string)au, level=(string)1.3,
profile=(string)main, width=(int)320, height=(int)240, framerat
e=(fraction)2500/83, pixel-aspect-ratio=(fraction)1/1, parsed=(boolean)true" !
decodebin use-buffering=TRUE ! glimagesink
