Decreases the difference to Anton Khirnovs patch v5
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

This patch adds CODEC_CAP_DELAY support to avcodec_decode_subtitle2.

For DVB teletext decoding, a single teletext packet can contain multiple
teletext pages. In order to support that, the teletext decoder may buffer
some pages.

The flag was and is intended to be a sane default and thus does not enable
time consuming checks. This also matches how the flag is used in decoders and
demuxers.

Don't use word-size multiplications if size == 2, and if we're using
SIMD instructions (size >= 8), complete leftover 4byte sets using movd,
not mov. Both of these changes lead to minor speedups.

The image size of the destination image was used to determine if a source
image was positioned outside the destination image, that no intersection
could occur.  Actually for these two cases the size of the source image
has to be used!

User may cut off a weird position and send a packet from there.
This avoids returning as invalid data immediately.
