reorganize octave_config_info again
* build-env-features.sh: Don't include ENABLE_ items in the output.
* toplev.cc (find_config_info): New static function.
(Foctave_config_info): Put Octave configuration info in the main
struct. Put the build system features and build environment info in
substructures. Allow searching of all elements by keyword.
* __have_feature__.m, doc/interpreter/testfun.txi:
Fix name of build features substructure element.
* geometryimages.m, interpimages.m, plotimages.m, sparseimages.m,
splineimages.m: Use __have_feature__ to check for OSMESA.
