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.

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

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.

Don't use GINT_TO_POINTER and GPOINTER_TO_INT with GTypes, this
can break horribly if sizeof(GType) happens to be bigger than
sizeof(int), because GPOINTER_TO_INT might then chop off some bits
of our GType (the reason this seems to works nevertheless is the
put-current-type-also-as-value-0-into-the-hash-table-as-fallback
hack used in the current code).
In any case, instead of just fixing this, let's not use a hash table
with GTypes here at all. g_type_{set|get}_qdata() seems to do the
job just as well.

Cleanup on demuxer registration.
Bumped flv demuxer to RANK_MARGINAL since it proved solid enough.
Will have to go over more demuxers, for which we don't have any
gst-plugins-* alternative, to figure out which ones can move to
RANK_MARGINAL too.

Original commit message from CVS:

Give ffmpeg demuxers a rank of NONE for the time being, so that
they are not auto-plugged; they are not stable enough for that
yet (e.g. #337785). Don't register AAC demuxer, it's not really
useful and can't be used as faad replacement (#338928).

Register id3 demuxer, avi demuxer and ogg demuxer with
