In particular, avoid improper use of the term "channels" in place of
"planes", and fix erroneous documentation for the linesize parameter.

Fix warning when compiling boxblur.

While this is technically a major API break, practically there will be no
one using that function since the filtering API is mostly private, so
that function alone is not usable.

This reverts parts of e0c6cce4. There is external mmx asm that
requires this alignment.

This fixes crashes when using swscale in builds with external mmx,
without inline assembly.

This separates code relying on inline from that relying on external
assembly and fixes instances where the coalesced check was incorrect.

A flashsv2 block may have a "diff block" to indicate which scan lines of
the block are actually encoded.  However, this diff block need not be
used when the entire block is coded.
