Subject: At least made the evar type opaque! There are still 5 remaining
 unsafe casts of ints to evars.

- 2 in Evarutil and Goal which are really needed, even though the Goal
one could (and should) be removed;
- 2 in G_xml and Detyping that are there for completeness sake, but
that might be made anomalies altogether;
- 1 in Newring which is quite dubious at best, and should be fixed.
