fcmp++: compilation fixes + misc. cleanup

Browse Source 
- Removed call to hash_init_point in constructor
- Replaced global static CURVE_TREES_V1 with a smart pointer
- Don't need to link Rust static lib when including curve_trees.h
- leaves table doesn't need dupsort flags, all leaves should be
unique by key
- rename fcmp -> fcmp_pp
- return when 0 leaves passed into trim_tree
