This is another API-incompatible change in recent history, and we do not want to touch this location twice (also from user perspective), A new major version of JavaSMT is required anyway.
The previous implementation did not correctly encode smodule-by-zero. Additionally, using a basis of srem instead of urem allows to simplify the encoding.
The hardest part of programming is documentation :-)

As discussed in #360, the
.modulo()method on the BitvectorFormulaManager API is misleading, because it creates a{s,u}remoperation. Therefore, we deprecate the method, and add separate.smod()and.rem()methods.The (now deprecated)
.modulo()operation delegates to the.rem()operation.
