New string utility functions to replace caseless_str for liboctave (bug #48726) * oct-string.h, oct-string.cc: new files that implement strcmp, strcmpi, strncmp, and strncmpi functions in the new octave::string namespace. This functions behave like the ones available in the Octave interpreter. * libinterp/corefcn/strfns.cc: make use of the new functions in liboctave. * libgui/graphics/QtHandlesUtils.cc, libgui/graphics/QtHandlesUtils.h, libinterp/corefcn/cellfun.cc, libinterp/dldfcn/chol.cc: make use of the new functions instead of caseless_str. * liboctave/util/module.mk: add new files to build system.
