Store palette data in the codec context, do not assume that the frame
allocated the first time by avctx->get_buffer will be returned again.

This requires to store the palette which comes with the first frame in
the context, and copy it to the following frames.

draw_slice() checks that the fade factor is < 65536 and only
calculates the fade if so. But the fade factor is clipped in
end_frame() by av_clip_uint16() to 65535, so the fade is calculated
for every frame.  This patch alters the check so that it compares with
< 65535 (UINT16_MAX).

draw_slice() checks that planes 0 and 1 of AVFilterBufferRef's data
are not NULL before manipulating planes 1 and 2. This patch makes the
check against planes 1 and 2. More senseful and possibly more robust.

In the loop:
    for (i=0; i<dstH; i++) {
        int chrI= i*c->chrDstH / dstH;

when i*c->chrDstH > INT_MAX this leads to an integer overflow, which
results in a negative value for chrI and in out-of-buffer reads. The
overflow is avoided by forcing int64_t arithmetic by casting i to
int64_t.

None of the raw audio files have timestamps, thus setting
start_time to 0 should be reasonable.

It does not make sense (DV is interleaved by design) and
it avoids a crash when the non-interleaved code tries to
use the priv_data of streams created by the DV demuxer.
The crash could be avoided differently, but then that stream
would still lack an index and would not play correctly in
non-interleaved mode.
Fixes e.g. samples/ffmpeg-bugs/roundup/issue1514/Dennis0002_video1.avi

Official AVI specification says that stream header in case of video contains
BITMAPINFO, which is equal to BITMAPINFOHEADER and optional palette. Currently
lavf AVI demuxer thinks otherwise which produces garbage on codecs that have
both palette and extradata (luckily, there are not so many such codecs).

An example of such file is:
http://samples.multimedia.cx/V-codecs/KMVC/baseball1.avi
(IIRC, MSS1 or MSS2 also had such situation but they are still not supported
by lavc).

As a side note, passing palette in extradata as it's been done previously is
not quite correct since proper _extra_ data is surplus bytes in
BITMAPINFOHEADER, not including palette.
