126b638ea0 Deprecate av_parse_video_frame_size() and av_parse_video_frame_rate() 
in favor of the newly added corresponding functions
av_parse_video_size() and av_parse_video_rate() defined in
libavcore/parseutils.h.

This change also adds a linking-time dependency of libavcodec and of
libavfilter on libavcore.

9dd9d67bd0 Define static functions fill_image_linesize() and 
fill_image_data_ptr(). ff_fill_linesize() and ff_fill_pointer() now wrap
these functions.

The new functions are more generic, and are going to be exported in a
future patch.

future new optimizations (imagine a sse5) much easier. Also fix a bug where

e3f7bf774c Fix SPLATB_REG mess. Used to be a if/elseif/elseif/elseif spaghetti, so this 
splits it into small optimization-specific macros which are selected for each
DSP function. The advantage of this approach is that the sse4 functions now
use the ssse3 codepath also without needing an explicit sse4 codepath.

Don't prefetch reference frames that were used less than 1/32th of the time so

3fc548df28 Make ff_inverse stay with libavutil, and optional copy it to libavcodec. 
The ff_inverse table is used by FASTDIV macro, defined in libavutil, but up
to now the table was defined only in libavcodec.

After this change, the main copy of ff_inverse is part of libavutil (just
like FASTDIV), but if CONFIG_SMALL is unset, then a different copy is made
available to libavcodec, to avoid the performance penalty of using an
external look up table.

Dynamic linking works, because the libraries are linked with -Bsymbolic, so
the local copy of the symbol has priority over the external; static linking
works because the table is on a standalone object file in both libraries,
so the linker is able to discard one of the two.

Tested on Linux/x86-64 and Mac OS X/x86-64.

6526976f0c Remove FF_MM_SSE2/3 flags for CPUs where this is generally not faster than 
regular MMX code. Examples of this are the Core1 CPU. Instead, set a new flag,
FF_MM_SSE2/3SLOW, which can be checked for particular SSE2/3 functions that
have been checked specifically on such CPUs and are actually faster than
their MMX counterparts.

In addition, use this flag to enable particular VP8 and LPC SSE2 functions
that are faster than their MMX counterparts.

Based on a patch by Loren Merritt <lorenm AT u washington edu>.

3facfc99da Change function prototypes for width=8 inner and mbedge loopfilter functions 
so that it does both U and V planes at the same time. This will have speed
advantages when using SSE2 (or higher) optimizations, since we can do both
the U and V rows together in a single xmm register.

This also renames filter16 to filter16y and filter8 to filter8uv so that it's
more obvious what each function is used for.

b834becdae Pass the composition and ancillary ID for DVB subtitles via extradata instead 
of sub_id, this allows detecting when that information is not available and
just decode everything.
In addition extradata is required for many codecs and thus in contrast to
sub_id generally already passed on by any programs using libav*.
Also ask for a sample if we encounter a stream with multiple/changing IDs.
