class Advertise

Register a set of services.

These services will be discoverable via Service Discovery Protocol server.

All services advertising the same channel must be added at once - if services are already

registered on any channel advertised, registration will fail, the receiver will be closed

with ZX_ERR_ALREADY_BOUND and an error will be returned.

The ConnectionReceiver will get calls for connections to the channels included in the

`protocol_descriptor` or `alternative_protocol_descriptors` in the services advertised.

The receiver will be closed if there are any errors advertising.

The `ConnectionReceiver::OnRevoke` event can be used to synchronize revoking the

advertisement, if necessary. Closing the `ConnectionReceiver` protocol will also stop

advertising these services.

If the advertisement cannot be made for any reason, an error of `INVALID_ARGUMENTS`

will be returned and the receiver will be closed with a suitable epitaph.

Returns the set of services that are registered via the Service Discovery Protocol

server. The returned services may differ from the input `services` if any L2CAP protocol

descriptors request `PSM_DYNAMIC`. In this case, the `Profile` server shall assign a valid

PSM and include this value in the returned services.
