New patch,  faking of fields can be controlled by a #define .

I have checked in a patch for ncp to make it still work even when this
patch is applied.

The only other usage I can find of calling fvalue_ are from various
tap based functions but they all take care to make sure there is a
filter containing the fields being referenced by fvalue_ calls.
(which they have to since they are all called AFTER the tree hass been
pruned and these fields wouldnt be there anyway)

Please test.

The performance boost from doing this and when filtering is very significant.
