[sending] Remove transferring.

Browse Source 
Out of an abundance of caution, we:

1. Left in parsing support for transferring but internally made it rely on the
internals of sending.

2. Added a warning to tell people that transferring was going to
be removed very soon.

Now that we have given people some time, remove support for parsing
transferring.
