The basic problem is that the DRC engine does length testing and skew
testing by collecting all the diff pair constituent parts and pairing them
itself. Since each part is collected on its own, we need to ignore the
'B' unit when evaluating any conditional expressions. However, doing this
in general means that when evaluating "OwnClearance()" we also ignore the
'B' unit and return the diff pair CLEARANCE_CONSTRAINT when we shouldn't.
This implements a more discerning test which know what the current requested
constraint is when evaluating expressions.

When testing for a specific layer context, we should only return true if
the item either exists on that layer or if the context layer is
UNDEFINED_LAYER, meaning the layer value is not material to the test

We were already checking for zone-zone overlap but missing checks when
running against (possibly) buried vias as well as the general check

The lemon parser doesn't lend itself to short-circuiting booleans,
but if we defer processing until we fetch the second value when
processing the TR_OP_BOOLEAN opcode then we get to piggy-back on
C++'s boolean short-circuiting.
6.0 will be in the field for a long time, and the better the debugging
tools we have available the less costly it will be to maintain.

The main issue was a parameter mismatch which caused On^2 behaviour
for zone layers.
But there are several other performance optimizations here, along
with status bar updating for zones while running the dissallow test.

This was leaking windows headers and partial wx headers to 1084 compilation units......
This also means math/util.h is leaking to 1084 compilation units which seems a bit high too.
Push DRC zone RTrees into BOARD so that they can also be used by
insideArea.
All these caches are a bit of an encapsulation leak, but they make a
significant impact on performance.
