I removed unused parameters in the tests wherever it was trivial to do so. I'm trying to get the easy ones out of the way before we get into more involved discussions around this.

Most of these issues were due to functions whose definitions appear in header files; I changed those functions to be 'static inline' instead of just 'static' or 'inline', which kills the warning for such functions.
Other functions that were static or anonymous-namespaced but were unused in cpp files were probably called at some point but are no longer; someone who knows more than I do should probably scrub all the functions I either deleted or #if 0'ed out and make sure that the right thing is happening here.
Lots of unused variables removed, and one nasty const issue handled.
There remains a single warning in thirdparty/externals/cityhash/src/city.cc on line 146 related to a signed/unsigned mismatch. I don't know if we have control over this library so I didn't fix this one, but perhaps someone could do something about that one.
