The current default is provided in various Makefile.inc in some top-level directories and covers a good portion of the tree, but doesn't cover parts of the build a little deeper (e.g. libcasper). Provide a default in src.sys.mk and set WARNS to it in bsd.sys.mk if that variable is defined. This lets us relatively cleanly provide a default WARNS no matter where you're building in the src tree without breaking things outside of the tree. Crunchgen has been updated as a bootstrap tool to work on this change because it needs r365605 at a minimum to succeed. The cleanup necessary to successfully walk over this change on WITHOUT_CLEAN builds has been added. There is a supplemental project to this to list all of the warnings that are encountered when the environment has WARNS=6 NO_WERROR=yes: https://warns.kevans.dev -- this project will hopefully eventually go away in favor of CI doing a much better job than it.
