ffmpeg typefinders don't do bounds checking for small chunks of
data, so just skip them if we don't have a lot of data, to avoid
invalid memory access and/or crashes.
Cache any events we get from upstream before we're open, especially
tag events we may be getting from apedemux/id3demux or the like, and
push them downstream later when we've added our pads instead of just
dropping them silently. Fixes transcoding tags for Monkey's Audio
Files with preceding APE or ID3v2 tags (#586957). Add minimal unit
test for this.
Also push stream tags later after the global tags and the newsegment
event rather than right after creating the pad.
We do this, because the demuxer is initialized in the loop function. If it's not
initialized yet, that means the loop hasn't been entered... and therefore the
PIPE GCond will never be signalled.
Where no more data is available, av_read_frame just returns an error code
instead of making the difference between "I am not returning anything because
we finished reading" and "I am not returning anything because the underlying
read failed".
We differentiate between the two by looking at whether we outputted any
data previously or not.

Update ffmpeg/swscale snapshot to the latest revision and adjust
to API changes. Fixes bug #556405.
Require libavutil for swscale too when building with an external
ffmpeg and fix includes for external ffmpeg.

gst_pad_template_new() takes ownership of caps; ref them beforehand
since we want to keep using them afterwards.

Set flv demuxer to rank NONE, we have a better, working demuxer in -bad
and we don't want any bug reports about this one. Fixes#534783.

Original commit message from CVS:
* ext/ffmpeg/gstffmpegdec.c: (gst_ffmpegdec_register):
* ext/ffmpeg/gstffmpegdemux.c: (gst_ffmpegdemux_register):
Don't register the WavPack demuxer and decoder. They don't work,
we have better ones and the output of the demuxer/input of the
decoder is in a different format than what audio/x-wavpack of the
wavpack plugin is (it seems that the demuxer strips of the wavpack
headers from every frame).
This fixes typefinding of Wavpack files again, as the ffmpeg
typefinder was preffered for some reason and gave
application/x-gst_ff-wv instead of audio/x-wavpack.
Original commit message from CVS:
* ext/ffmpeg/gstffmpegdemux.c: (gst_ffmpegdemux_loop):
Fix demuxer to stop properly (emit an error message on the bus) if no
pads are linked. Use aggregated flow return values a bit more.

Don't return FALSE for the LATENCY event but instead forward it
