Zdenek Kabelac 88681f05f1 radix_tree: api change 
Instead of using 'key state & key end' uint8_t* switch to use
void* key, & size_t keylen.  This allows easier adaptation with
lvm code base with way too much casting with every use of function.

Also correctly mark const buffers to avoid compiled warnings and
casting.

Adapt the only bcache user ATM for API change.

Adapt unit test to match changed API.
