[roll] Roll fuchsia [audio][adr] First-reply WatchDevicesAdded

Method fuchsia_audio_device/Registry/WatchDevicesAdded is a
normal hanging-get, used to asynchronously notify clients of
device arrivals. Currently it pends until there is at least
one device, even the first time that a client calls this.

Change this to respond immediately to each client's FIRST
call to this method, even when this means returning an empty
vector. This enables clients to safely use the method
synchronously, on systems where there may not be any audio
devices.

In practice, ADR is eagerly started, and all devfs devices
are detected and initialized before the ADR receives the
first `WatchDevicesAdded` call. However, a subsequent CL
will ensure that this is the case even if ADR is not eagerly
started, by changing ADR's detection and initialization code
to wait for all preexisting devices to be fully initialized
before responding to this method.

Integration

This repository contains Fuchsia's Global Integration manifest files.

Making changes

All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.

Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance via the IRC channel #fuchsia on Freenode.

Obtaining the source

First install Jiri.

Next run:

$ jiri init
$ jiri import minimal https://fuchsia.googlesource.com/integration
$ jiri update

Third party

Third party projects should have their own subdirectory in ./third_party.
