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.

Fixes Ticket2896
An alternative to this would be to change the code to support any

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.
Athlon64:

1080744 decicycles in mmx, 32744 runs, 24 skips, 1.7x faster

Core2Quad:
