fe55c31976 lavc/elbg: rename ff_ symbols to avpriv_, so they can be used in shared libs
In particular, allows the use of elbg in other FFmpeg libraries, required
by the pending elbg filter.

ba87f0801d Remove explicit filename from Doxygen @file commands.
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

144b46f21b My commit at r14340 was not the right solution. For a monochromatic
frame, there will be only one centroid and it will be impossible to
find three distinct ones. It is better to just avoid shifting if
there are not three different centroids.

6bf8b04764 When picking a "high utility centroid" do not pick one
that has no corresponding points. Not only it is the
worst possible pick, but also the code was written
without this case in mind.

5916af1954 The codebook generator algorithm involves picking three
different codebook centroids ("high utility", "low
utility" and "closest to the low utility one"). This
change avoid the corner case of choosing two times the
same centroid.
