phobos commit, revision 1684


user: rsinfu

msg:
Fixed bugzilla 978: std.utf's toUTF* functions accept some invalid and reject some valid UTF.

* Fixed decode() to accept U+FFFE and U+FFFF.
* Changed some assert contracts (which check input for validity) to if-throw.
* Fixed static array argument to be passed by ref (regression).
