bd6a4aa10d flvdemux: Use aac codec-data to adjust channels if needed

flvdemux detect an audio channels of 2(stereo) when the AAC really is 1(mono).

307018da89 flvdemux: Don't pull passed the EOS 
When a truncated FLV is provided and processed in pull mode, we
may endup trying to pull passed EOS, causing a rather confusing

cfc1638ca5 flvdemux: Ignore invalid H.264 codec data 
This code basically skip over codec_data with empty payload. In
this case, the codec_data variable is the size of the header for
the CODEC part of Video Tag. The remaining is supposed to be the
H.264 codec data, hence should not be empty.

ee44e60f7b flvdemux: Refactor metadata tag handling 
The FLV header cannot be trusted to indicate video or
audio presence, as the comments already mention. Don't
delay pushing tags waiting for streams that might never
appear.

Tags are now pushed immediately after they change:
  - After parsing an onMetaData script object
  - After negotiating caps on a pad

bcbb8fc1da flvdemux: don't emit pad-added until caps are ready 
In other words, gst_pad_get_current_caps should never return NULL
in a pad-added callback from the demuxer.

Added tests for the two special cases with AAC and H.264 where this
would happen every time.

ac0141b6a0 flvdemux: Only set caps once if they don't change 
Previously we were setting new caps with the same content for every H264 or
AAC codec_data we found in the stream, spamming everything and causing
renegotiations.

c9b42951fe flvdemux: Don't create AAC/H264 caps without codec_data 
Instead delay creating the caps until we read the codec_data from the stream,
or fail if we get normal data before the codec_data.

AAC raw caps and H264 avc caps always need codec_data, setting caps on the pad
without them is going to make negotiation fail most of the time. Even if we
later set new caps with the codec_data, that's usually going to be too late.
