Redo r113722 - Add Pass(), which implements move semantics, to scoped_ptr, scoped_array....
(This undoes the revert in r114247. Win canaries still can't link, but
this change has been deemed safe).
Add Pass(), which implements move semantics, to scoped_ptr, scoped_array, and
scoped_ptr_malloc.
This modification to the scopers implements the "moveable but not copyable"
semantics that were introduced in C++11's unique_ptr<>.
With this, is now possible to use scopers as an argument type or a return type.
This signifies, in the type system, transfer of ownership into a function or out
of a function respectively. Calling, or returning such a function MUST use the
temporary resulting from a function or explicit cast.
This distinction makes it possible to avoid the implicit ownership transfer
issues of auto_ptr, but still allow us to have compiler enforced ownership
transfer.
Also adds a Passed() helper that allows using a scoper with Bind().
