build: add and use global EXTRA_WARNINGS from common/Make.rules

Browse source 
Define EXTRA_WARNINGS in the common/Make.rules helper so that adding
additional warnings can be done in one(-ish) location, and replace
locally defined C compiler warning flags with EXTRA_WARNINGS in most
locations in the build tree.

v2: issue a warning for any compiler option that the compiler does not
    support
