The daemon-side reverse functions depended on handle_forward_request:
move them back instead of duplicating the logic we had in
handle_host_request. Accomplish what we originally wanted to do in this
change by changing the transport argument of handle_forward_request to a
std::function that acquires a transport, either via
acquire_one_transport or immediately returning a value that we already
have.
As a side effect, fix a bug where we would emit spurious errors for host
service requests.

Let minadbd override daemon services by pulling out the daemon services
into a separate translation unit, that isn't compiled into libadbd.
