Enables -Weverything and -Werror, with just a few exceptions for
warnings we can't (or shouldn't need to) work around.
Cherry pick of I034abec27bf4020d84af60d7acc1939c59986dd6 plus a
couple of minor changes to CpuConsumer.cpp to make it work with a
prior change:
Uncomment CC_LOGV on line 46
Change C-style cast to static_cast on line 71
