context: avoid using a context object as a changeid
I find it misleading to pass changeid=changectx. It currently works to
do that because there's weird (IMO) handling of it in
basectx.__new__. I'm planning on removing that code. Passing changeid
as "changeid" and context as "context" makes it more readable.
Note that the documentation of filectx.__init__ doesn't even seem to
be aware that a changeid can be a context ("changeset revision, node,
or tag").
