Sync rust_chan's deref() method with rustc's code.
...
If the channel is associated with a port then the destructor will assert.
Additionally, destruction of the object is not always appropriate. This brings
the deref() method into sync with the behavior of generated rust code which
only invokes destroy() once the reference count goes to 0.

Add macro for refcounting runtime structures.
...
The macro with the extra dtor parameter is intended for structures like
rust_chan which may not necessarily delete themselves when the ref count
becomes 0. This functionality will be used in an upcoming changeset.

Move the channel destroy code into rust_chan.
...
This lets native code more easily destroy channels since directly deleting a
channel is not always the right way to destroy it.

Move channel cloning logic into a method on rust_chan.
...
This will allow us to more easily clone channels from native code.
