This patch would allocate zero-sized blocks for strides that were
zero. This lead to a problem in planarCopyWrapper() which tests
dst[plane] to see if data should be copied for that plane.

I have attached two new patches. The first patch makes
planarCopyWrapper() check for both dst[plane] and dstStride[plane],
and the second patch does the same the previous patch did but only
allocates when stride != 0.

With patch2, patch1 shouldn't be necessary, but it makes swscale more
robust for bogus input (allocated planes but no stride).
