Added an option for unrolling long match copying
Usually useless and costing +57 bytes, this option can bring dramatic performance improvements on very compressible data dominated by long matches

+0.2% speed
also, added an option to unroll LDIR for longer matches (which adds 38 bytes, but can be significantly faster for files with many long matches)

This update is mostly about better integration of improvements by uniabis, with spke contributing several smaller size optimizations.
