Relaxed the constraint introduced in r14190 that froze the existing
evars when rewriting. Use it for autorewrite and subst. Accept evars
instantiation in multi_rewrite so that rewrite alone remains
compatible (it is used in contribs, e.g. Godel, in places where it
does not seem absurd to allow it), but there are no good reason for
it. Comments welcome.
+ addition of some tests for rewriting (one being related to commit 14217)
