I've removed this entry. I was fooled by defvaralias being new.

I'm waiting to see if Richard decides that define-obsolete-function-alias
should be added too. These two functions are so similar to the two that
I've just documented, externally at least, that I wonder if they could
be described somewhere centrally in the Lisp manual i.e a link from the
nodes 'Defining Variables' and 'Defining Functions'to one called
'Obsoletion'.
