Add BDD utilities; use them for narrowing/propagation of linear equality constraints ( #5192 )
...
* Add a few helper methods for encoding sets of integers as BDDs
* Use BDD functions in solver
* Add bdd::find_int
* Use bdd::find_int in solver
* Add narrowing for linear equality constraints
* Simplify code for linear propagation
* Add test for later
* Narrowing can only handle linear constraints with a single variable
* Need to push_cjust
