    Disable same warnings for normal builds as for validate (#10223)
    
    The default validate settings currently disable some warnings in the
    libraries. This patch moves those settings to a new file called
    `mk/warnings.mk`, and applies them also to normal builds.
    
    Through uncommenting a line in build.mk, developers can now build with
    -Werror.
    
    -Werror is not the default, because:
    * We can not guarantee that the build is warning free on platforms we
      don't run regularly run validate (as part of continuous integration
      systems), and we still want the build to go through on those
      platforms.
    * quoting rwbarton on irc > "I think -Werror by default has come up in
      the past and the argument was that it is too annoying when you are
      doing nontrivial development"
