e7843db3df swscale: fix invalid conversions and memory problems.
Fixes problems where rgbToRgbWrapper() is called even though it doesn't
support this particular conversion (e.g. converting from RGB444 to
anything). Thirdly, fixes issues where rgbToRgbWrapper() is called for
non-native endiannness conversions (e.g. RGB555BE on a LE system).
Fourthly, fixes crashes when converting from e.g. monowhite to
monowhite, which calls planarCopyWrapper() and overwrites/reads because
n_bytes != n_pixels.

6e9bb5aa3e swscale: prevent invalid writes in packed_16bpc_bswap
Writes past the end of the destination buffer were occuring when its
stride was smaller than the stride of the source. Fixes Bug #183.

42ba12888b Do not convert RGB buffer at once when stride does not fit exact samples.
When converting RGB format to RGB format with the same bits per sample,
unscaled path performs conversion on the whole buffer at once. For
non-multiple-of-16 BGR24 to RGB24 conversion it means that padding at the
end of line will be converted too. Since it may be of arbitrary length
(e.g. 8 bytes), operating on the whole buffer produces obviously wrong
results.
