Deprecated sizemax function (bug #47469). * scripts/deprecated/sizemax.m: New m-file to produce a warning and provide sizemax() behavior for the next two Octave releases. * scripts/deprecated/module.mk: Add sizemax.m to build system. * bitfcns.cc (Fsizemax): Remove function. * dim-vector.h (dim_max): Add OCTAVE_DEPRECATED macro to function. * dim-vector.cc (safe_numel): Call std::numeric_limits<octave_idx_type>::max rather than dim_max(). * __sprand__.m: Replace sizemax() invocation with new code. * numbers.txi: Remove DOCSTRING entry for sizemax and add text explaining actual size limitation imposed by size of index pointers when Octave was compiled.
