Sean Bowe 1254e4f245
Ensure that selectors are only used in simple ways. 
You cannot add an expression containing a Selector to another expression.

You cannot multiply an expression containing a Selector by another expression
that also has a selector.

Jack Grigg ed2295b077 Add trait methods and general APIs for defining circuit constants 
During circuit configuration, fixed columns can be marked as suitable
for containing arbitrary constant values (i.e. the columns aren't
encumbered by constraints that preclude arbitrary values).

During synthesis, circuits can now request that the layouter assign
an advice cell within a region, to some specified constant value. It
is the layouter's responsibility to find space within the previously
marked fixed columns, in which to assign the constant.

This commit intentionally does not compile.

Jack Grigg 7dae8698b6 MockProver: Poison unusable advice cells 
Circuit developers need to use selectors (or equivalent) to prevent their
custom gates from being active on unusable rows. By marking the advice
cells in these rows as "poisoned" and tracking this through expressions,
we can provide a better error message to developers that indicates the
missing selector issue.

Closes zcash/halo2#329.
