This more evenly distributes the load between threads

This also fixes the chroma filtering where the filter was applied twice

  cpu: Include common.h for av_popcount64
Merged-by: Michael Niedermayer <michaelni@gmx.at>

Due the crappy issue of classes having to be unique,
we cannot even have classes with identical content,
otherwise the compiler or linker is free to merge them,
giving the same result and bugs as if we had only one class.
Besides redesigning the option code to handle this correctly
I see only the option of requiring any two classes to have
different names, but the list of requirements for
AVClasses is getting kind of unmanageable.

Fixes compilation when the macros are empty and the label above ends up
containing no statement. Also makes usage of these macro consistent
(some already have a semi colon, some others don't).

Mostly based on libavcodec's

It will be useful in lavfi, and could conceivably be useful to the user
applications as well.
