- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Final #include tweak.

Approved by: re (blanket)

Numerous fixes to make Unbound compile cleanly:

- cast through void * to silence alignment warnings (presumably false
positives resulting from poor API design)

- constify a few function arguments

- move prototypes for callbacks into a common header

- now that the prototypes are in scope, fix instances of function
definitions that don't match the prototype or what the caller
actually passes

- hide a conditionally unused global variable behind the same #ifdef
that controls its use
