Attachment: Add simple varargs support.

Limitations on varargs:

- must be [noscript], though we _could_ probably make it work for
sufficiently-motivated xptcinvoke users; and

- must have |void| IDL return, because we don't support retval (IDL-implied, or
explicit) in any position but the last, and varargs _really_ needs to be last. 
Use an |out|, it's basically the same in C++ anyway, and since we require
[noscript]...

What say ye, vlad?
