I'd like to see Flash Player and other plugins use the existing CSP
policy mechanisms when possible/applicable.  We tried to keep the
directives scenario-centric rather than API-centric, though there are
some notable exceptions.

Plugins will probably require extensions to support scenarios that
aren't currently defined, but to define a whole new set of extensions
specifically for Flash Player would likely requiring re-defining many of
the existing directives around loading of scripts, image, media, fonts, etc.
