Fix issue #1074, improve non-fatal error handling (#1075)

Commit 54d24c786d6a843cc72dfb5e377603349ea5e420 was
changing CVC4 to handle certain non-fatal errors
(such as calling get-unsat-core without a proceding
unsat check-sat command) without terminating the
solver. In the case of get-unsat-cores, the changes
lead to the solver crashing because it was trying to
print an unsat core initialized with the default
constructor, so the member variable d_smt was NULL,
which lead to a dereference of a null pointer.

One of the issues of the way non-fatal errors were
handled was that the error reporting was done in the
invoke() method of the command instead of the
printResult() method, which lead to the error
described above and other issues such as a call to
get-value printing a value after reporting an error.

This commit aims to improve the design by adding a
RecoverableModalException for errors that the solver
can recover from and CommandRecoverableFailure to
communicate that a command failed in a way that does
not prohibit the solver from continuing to execute.
The exception RecoverableModalException is thrown by
the SMTEngine and the commands catch it and turn it
into a CommandRecoverableFailure. The commit changes
all error conditions from the commit above and adds a
regression test for them.

Fix model construction for parametric types (#1059)

Fix model construction for parametric types so that we enumerate types in order of dependencies, and avoid subterms of previously enumerated values.

There was a bug in model construction for parametric types which was related to enumerating values that are subterms of other previously enumerated values created during model construction (which were not recorded).

This commit adds all subterms of values we enumerate to the "already used value" sets of their respective types, as reflected in the changes to TypeSet.

There is an extra wrinkle in making the above change, which was caught by the regression test/regress/regress0/fmf/dt-proper-model.smt2. The issue is specific to finite model finding and can be corrected by ensuring that base types (e.g. uninterpreted sorts) are enumerated first.

The change to TheoryModel::buildModel that replaces "allTypes" with "type_list" fixes this wrinkle. This constructs a partially ordered list of types where T1 comes before T2 if values of T2 can contain terms of type T1 but not vice versa. Ordering our enumeration in this way is probably a good idea in general. This ensures we enumerate values for equivalence classes of e.g. Int before (Array Int Int) and means we exclude fewer intermediate values during model construction.
