Standardize SMT-LIBv2 set of logics to use LogicInfo.
Previously, SMT-LIB logics were treated specially, as in SMT-LIB v1.2.
This led to inconsistencies---such as nonstandard logics like "QF_LIRA"
being accepted in set-logic but not providing the "Real" sort. Now,
the LogicInfo is used and queried, so nonstandard logics should work
fine and declare the correct symbols. SMT-LIB v1.2, unfortunately,
can't take advantage of this fully since symbols like "Array" have
substantially different meanings in different logics.

Don't allow get-model & co after a user push/pop
This makes us more strictly adhere to the spec, but it's useful anyway:
previously we would support a get-model until the problem was explicitly
changed with e.g. a new assertion. That meant you could check-sat, then
pop, then get-model, but you'd only get the part of the model still in
scope. This is strange, and would likely lead to problems, so it's now
disabled.
