Weekend work. The main points:
* Type::getCardinality() returns the cardinality for for all types.
Theories give a cardinality in the their kinds file. For
cardinalities that depend on a type argument, a "cardinality
computer" function is named in the kinds file, which takes a
TypeNode and returns its cardinality.
* There's a bitmap for the set of "active theories" in the
TheoryEngine. Theories become "active" when a term that is owned by
them, or whose type is owned by them, is pre-registered (run CVC4
with --verbose to see theory activation). Non-active theories don't
get any calls for check() or propagate() or anything, and if we're
running in single-theory mode, the shared term manager doesn't have
to get involved. This is really important for get() performance
(which can only skimp on walking the entire sub-DAG only if the
theory doesn't require it AND the shared term manager doesn't
require it).
* TheoryEngine now does not call presolve(), registerTerm(),
notifyRestart(), etc., on a Theory if that theory doesn't declare
that property in its kinds file. To avoid coding errors,
mktheorytraits greps the theory header and gives warnings if:
+ the theory appears to declare one of the functions (check,
propagate, etc.) that isn't listed among its kinds file properties
(but probably should be)
+ the theory appears NOT to declare one of the functions listed in
its kinds file properties
