maint: Collapse interpfcn and interpfcn-core directories into corefcn directory. * libgui/src/module.mk: Remove -I references to interp-core, interpfcn, add reference to corefcn. * libinterp/Makefile.am: Remove -I references to interp-core, interpfcn, add reference to corefcn. * libinterp/corefcn/module.mk: Add files from interp-core, interpfcn to build system. Copy over special rules from module.mk files in interp-core andd interpfcn. * src/Makefile.am: Replace references to interp-core, interpfcn with those to corefcn. * libinterp/corefcn/Cell.cc,
