ffmpeg: fix streamcopy with side data
The issue is that, when the main packet data buffer is changed, streamcopy
uses a temporary new packet to store that buffer, frees the old packet, and
replace it with the new packet.
However, in doing so, it forgets about the side data, which gets freed, but
is still needed and referenced. Then, when the packet gets freed again in
the normal code path, it attempts to free its side data which has already
been freed.
Therefore, simply avoid the first free on side data by removing that side
data from the packet.
Fixes ticket #3773.

avconv: Set audio filter time base to the sample rate
If the output frame size is smaller than the input sample rate,
and the input stream time base corresponds exactly to the input
frame size (getting input packet timestamps like 0, 1, 2, 3, 4 etc),
the output timestamps from the filter will be like
0, 1, 2, 3, 4, 4, 5 ..., leadning to non-monotone timestamps later.
A concrete example is input mp3 data having frame sizes of 1152
samples, transcoded to aac with 1024 sample frames.
By setting the audio filter time base to the sample rate, we will
get sensible timestamps for all output packets, regardless of
the ratio between the input and output frame sizes.
