Read my last review comments again.

The policies are orthogonal but both change tll:

* The signature policy affects allowed combinations of old and new
  signature calls (where "new" includes LINK_(PUBLIC|PRIVATE|INTERFACE)).
  The OLD behavior allows old AND new signature calls on the same target.
  The NEW behavior allows old XOR new signature calls on the same target.
  It has no effect on link interface properties, set or get.

* The interface policy affects which properties define the link interface.
  In OLD behavior tll populates the old properties and CMake uses them.
  In NEW behavior tll populates the new property and CMake uses it.
  It has no effect on allowed tll signatures.
