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.
