VTY: ensure all cmd_elements are declared 'static'
While doing 'nm' on a VTY-using object file I noticed that all
cmd_elements are global symbols, which is not good.
Unfortuantely there are some vty-internal cmd_elements that need
to span across object files, so I had to introduce gDEFUN()
and gALIAS(). The old macros now all declare static structures.
