veyron2/ipc: force all protocols, including tcp, to be registered.
- this change implements and uses a consistent mechanism for
registering the stream transport protocols to be used with RPC.
- it treats 'tcp' the same as any other 'user defined' protocol, such
as websockets or unixfd
- protocols are generally registered by importing their package, whose
init function performs the actual registration.
- the protocol packages should only be imported by profiles.
- in a future change, I propose to move lib/tcp, lib/websocket and lib/unixfd
to profiles/internal.
