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.

So far fbdev_enc device picked up first video stream and ignored others.
It is required to provide exactly one video stream now.

Current implementation didn't include duration of
last processed packet.
Also remove access to st->cur_dts and replace with pkt->pts.

It does not make sense in the vast majority of use cases, no currently
defined AV_OPT_TYPE_FLAGS options in Libav set the range to anything
nontrivial, and many of those get it wrong (the "correct" range is
INT_MIN to INT_MAX so that the builtin constant "all" works).
A VUI doesn't contain anything strictly necessary for decoding.
Apparently there are many samples with truncated VUIs in the wild, this
commit should allow decoding them.
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.

This is a regression, did not bisect so dont know what caused it but
likely some changes to the command line handling code.

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!
