bdd_uniquecomp, bdd_appexcomp, bdd_appallcomp, bdd_appunicomp): Declare for C and C++. * src/bddop.c (CACHEID_EXISTC, CACHEID_FORALLC, CACHEID_UNIQUEC, CACHEID_APPEXC, CACHEID_APPALC, CACHEID_APPUNCC): New macros. (quatvarsetcomp): New variables. (varset2vartable): Take a second argument to indicate negation, set quatvarsetcomp. (INVARSET): Honor quatvarsetcomp. (quantify): New function, extracted from bdd_exist, bdd_forall, and bdd_appunicomp. (bdd_exist, bdd_forall, bdd_appunicomp): Use quantify. (bdd_existcomp, bdd_forallcomp, bdd_appunicompcomp): New functions. (appquantify): New function, extracted from bdd_appex, bdd_appall, and bdd_appuni. (bdd_appex, bdd_appall, bdd_appuni): Use appquantify. (bdd_appexcomp, bdd_appallcomp, bdd_appunicomp): New functions. * src/bddop.c (bdd_support): Return bddtrue when the support is empty, because variable sets are conjunctions.
