shill: enable (don't disable) -Wunused
having fixed an unused parameter in the dbus-c++ headers, those
headers no longer have unused parameters. so, if we fix up unused
parameters in shill code, we can compile with -Wunused. (this is
implied by -Wall, as long as we don't override with -Wno-unused.)
BUG=chromium-os:20779
TEST=unittests
- comment out unused parameters in function definitions
- remove some unused local variables
- also: fix an old-style cast
