cfd0486582 Catch exceptions by const-reference 
Exceptions caught by value incur needless cost in C++, most of them can
be caught by const-reference, especially as nearly none are actually
used. This could allow compiler generate a slightly more efficient code.

4abab8aaf5 Fix bug in qe_term_graph 
In merge, parents of A instead of parents of B were traversed.

infinite loop in to_lits()

baa96909cc mb-skolem for arithmetic with model repair 
The contract is that users of mb-skolem ensure that
interface equalities are preserved (by adding a
sufficient set of disequalities, such as a chain
x1 < x2 < x3 .., to force that solutions for
x_i does not clash).
