safe cast between SuiteSparse_long and octave_idx_type pointers (bug #50510) * oct-sparse.cc: New file. * liboctave/util/module.mk: Update. * oct-sparse.h, oct-sparse.cc (octave::suitesparse_integer): New typedef. (octave::to_suitesparse_intptr, octave::to_octave_idx_type_ptr): New functions. * amd.cc, ccolamd.cc, colamd.cc, dmperm.cc, symbfact.cc, CSparse.cc, dSparse.cc, sparse-dmsolve.cc, sparse-lu.cc, sparse-qr.cc: Use new functions and typedef to avoid conflicts between pointers to octave_idx_type and SuiteSparse_long on systems where they are equivalent types but have incompatible definitions (long long int * vs. long int *, for example, when both are 64-bits wide).
