Generalizing the uses of tactic scopes everywhere.

This feature allows the user to write "let x := open_constr(foo) in ..." for instance
without having to resort to tactic notations. Some changes have been introduced in
the parsing of ad-hoc argument scopes, e.g. one has to put parentheses around
constr:(...) and ltac:(...) in tactics. This breaks badly written scripts, although
it is easy to be forward-compatible by preemptively putting thoses parentheses.
