octave: libinterp/corefcn/utils.cc annotate

annotate libinterp/corefcn/utils.cc @ 25440:893344cee100

rename defaults source files to installation-data * installation-data.h, installation-data.cc: New files, adapted from defaults.h and defaults.cc. Include installation-data.h instead of defaults.h, but only in files that require it. * defaults.h: Preserve for backward compatibility. Define deprecated functions as inline. * libinterp/corefcn/module.mk: Update.
