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.
