Subject: 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)
