Nits for 1.5.10

[Dag-Erling Smørgrav]

The following are changes I had to make to integrate 1.5.10 into FreeBSD
head, rebased to unbound trunk.

1) lz_type() must either have a prototype or be declared static.  Since
   it isn't used outside its compilation unit, I chose the latter.

 	struct comm_reply* repinfo, struct rbtree_t* override_tree, int* tag,

2) Unnecessary casts, some of which discard qualifiers and therefore
   break the build at higher warning levels.  Note that needlessly
   discarding a const qualifier can prevent certain optimizations.
