Libav, for some reason, merged this as a public API function. This will
aid in future merges.

A define is left for backwards compat, just in case some person
used it, since it is in a public header.

Logic for handling single frame in yadif (0f9f24c9), caused deint=1 (e.g., yadif=0:-1:1) to output extra duplicate leading frame:

ffmpeg -i fate-suite/ffmpeg-synthetic/vsynth1/%02d.pgm  -vf yadif=0:-1:1,showinfo -f null -y /dev/null
 [Parsed_showinfo_1 @ 0x1d967d0] n:0 pts:0 pts_time:0 pos:-1 fmt:gray sar:0/1 s:352x432 i:P iskey:1 type:I checksum:E457EEA0 plane_checksum:[E457EEA0] mean:[126] stdev:[46.6]

(Outputs 51 frames)

After patch, vf "yadif=0:-1:1" behaves correctly (like "yadif=0:-1:0") and outputs 50 frames, first two:

Fixes Ticket2896

An alternative to this would be to change the code to support any
stride.
The condition of differing strides should be rare.
If theres no speedloss supporting any stride would be better

Always use the special filter for the first and last 3 columns (only).

Changes made in 64ed397 slowed the filter to just under 3/4 of what it
was.  This commit restores the speed while maintaining identical output.

This is a fairly dumb copy of the assembly for 8-bit samples but it
works and produces identical output to the C version.  The options have
been tested on an Athlon64 and a Core2Quad.
