0.7 requires dbus 1.1 or greater (for system bus activation), so make that explicit, and remove compat code for D-Bus 0.6 and earlier. Consolidate the various glib pkgconfig checks into one, since most anything will require gthread, glib, and gobject anyway. Fixup the docs makefile to be more automake-compatible and let 'make clean' actually work correctly when docs are built.
