Description

The dbfwfilter could deny functions like it denies columns. An example rule would be like this:

rule no_func deny functions user sum min max

This would block the user(), sum(), min() and max() functions.

Moved to 1.5 because the necessary functionality - exposing functions of a query - is not available.

Further, the regexp based filtering can to a certain extent be used for filtering out/in functions usage.

Removed fix-version. Need to be decided if and when this feature will be included.

The dbfwfilter now supports the function rule type which accepts a list of function names as its parameter.
