Replace `xint_value` and related functions with stricter versions (bug #65538) The conversion function `xint_value`, `xbool_value`, and `xidx_type_value` were being used to convert input arguments to integers, booleans, or index values respectively, and to provide a meaningful error message if the conversion failed. The problem, as described in bug #65538, is that this allows user code like `all (true (3), 2.718)` to be silently converted to `all (true (3), 2)` instead of giving an error that the dimension needs to be an integer. The same happens with `cell (e, pi)`, which silently creates a 2x3 cell array. In both cases, this permissive conversion is a Matlab incompatibility. This patch provides an analogue of `xint_value` called `yint_value` that uses a stricter conversion to integer, and also does the same for `bool` and `idx_type` conversions. With this patch, passing non-integer sizes now gives an error, and passing non-boolean values to boolean arguments now give a warning. * libinterp/octave-value/ov.h: Define new functions `strict_int_value` and `strict_bool_value` and declare new function `strict_idx_type_value`. Declare corresponding new wrapper functions `yint_value`, `ybool_value`, and `yidx_type_value`. * libinterp/octave-value/ov.cc: Define `strict_idx_type_value`. Define `yint_value`, `ybool_value`, and `yidx_type_value` using the existing XVALUE_EXTRACTOR macro. * Replace the corresponding function calls in: __eigs__.cc, besselj.cc, bitfcns.cc, data.cc, file-io.cc, interpreter.cc, jsondecode.cc, load-path.cc, oct-stream.cc, ov-cell.cc, psi.cc, pt-eval.cc, sparse.cc, strfns.cc, syscalls.cc, time.cc, utils.cc, variables.cc, __glpk__.cc, __ode15__.cc, pt-eval.cc * NEWS.10.md: Add note about the Matlab compatibility of this patch. Incidentally, the new conversion functions allow a FIXME note inside `fcntl` to be addressed and removed.
