- On writes, only send a transfer parameters update after the first
chunk with an incorrect offset. This prevents storms of transfer
parameters updates when early packets in the window are dropped. If
that update is dropped, the client time out and resend its last chunk.
- Move transfer logic to the ServerContext class.
- Introduce the ClientConnection class, which represents a connection
to a particular pw_transfer client. It bundles the server writers with
the transfer parameters for those streams.

This starts an implementation of a C++ transfer client suitable for
device to device transfers. Both read and write transfer support is
added. The code is incomplete and untested; pw_rpc raw clients are
required before this can be functional.

This adds support for client-to-server write transfers to the C++
transfer service. Additionally, the transfer service is updated to
require the maximum chunk size as a constructor argument, as this
cannot easily be determined from the RPC system.
