[mv3] Various fixes and code review
Fixed trusted sites not being excluded from declarative
scripting.

Assign "uBOL_"-prefixed name to anonymous scripting functions
so that they can be easily found in performance profiler results
in dev tools.

Imrpove spread of chunks of filters across declarative scripting
files.
