Change internalmode to be an intrinsic variable
Currently, internalmode is a special word to set an internal state
variable. Because this series adds variables anyway, change this to
be a variable instead.
I saw some commits in the history that made sure that chew did not
leak memory, so I put some extra effort into trying to handle this for
variables as well.
