lib/reduce: add empty library, include, unit tests 



reduce will be a block compression algorithm designed
specifically for SPDK.  It is called "reduce" because
it reduces the data size on disk.

This patch just adds the shell of a library, include
files and unit tests.  This will be fleshed out in
the rest of the patches in this series.
