rename gui directory to libgu * libgui: Rename from gui. * .hgsub (libgui/qterminal): Rename from gui/qterminal. * Makefile.am (GUIDIR): Set to libgui instead of gui if AMCOND_BUILD_GUI is true. * configure.ac (AC_CONFIG_FILES): Update list for directory renaming. * Makefile.am (.NOTPARALLEL): Delete. List octave.html/index.html as the primary HTML target, not octave.html. (octave.html): New target for making the octave.html directory. (octave.pdf): Depend on octave.dvi. * images.awk: In generated rules for png files, depend on octave.html, not octave.html/index.html. * src/Makefile.am (OCTAVE_GUI_CPPFLAGS, OCTAVE_GUI_LIBS): Update for directory renaming. (CLEANFILES): Fix typo. * fntests.m (src_tree): Use libinterp, not src.
