split libinterp from src * libinterp: New directory. Move all files from src directory here except Makefile.am, main.cc, main-cli.cc, mkoctfile.in.cc, mkoctfilr.in.sh, octave-config.in.cc, octave-config.in.sh. * libinterp/Makefile.am: New file, extracted from src/Makefile.am. * src/Makefile.am: Delete everything except targets and definitions needed to build and link main and utility programs. * Makefile.am (SUBDIRS): Include libinterp in the list. * autogen.sh: Run config-module.sh in libinterp/dldfcn directory, not src/dldfcn directory. * configure.ac (AC_CONFIG_SRCDIR): Use libinterp/octave.cc, not src/octave.cc. (DL_LDFLAGS, LIBOCTINTERP): Use libinterp, not src. (AC_CONFIG_FILES): Include libinterp/Makefile in the list. * find-docstring-files.sh: Look in libinterp, not src. * gui/src/Makefile.am (liboctgui_la_CPPFLAGS): Find header files in libinterp, not src.
