* merge cost calculation functions (BitsEntropy() and HuffmanCost())
* have HistogramAdd() specialized into separate functions
* use threshold to bail-out early
* revamp code a bit
* also: save memory by freeing free(histogram_image)

subdirectories with more than one target can have the install targets
run in parallel with make -jN. group the shared headers in one place to
produce a common install target.

Reported to eventually be 4% on ARM
(see https://code.google.com/p/webp/issues/detail?id=134 for details)
We might activate it selectively later...
Output values is not bitwise the same as the LUT-based
