tests/test-classifier.c used to include lib/classifier.c to gain
access to the internal data structures and some utility functions.
This was confusing, so this patch splits the relevant groups of
classifier internal definations to a new file
(lib/classifier-private.h), which is included by both lib/classifier.c
and tests/test-classifier.c. Other use of the new file is
discouraged.
