shill: WiFiProvider: Move Service vector to WiFiProvider
Remove the services_ vector from the WiFi Device and move it
to the WiFiProvider. Also remove the WiFi device initializer
from the WiFiService, so it doesn't have an early or permanent
binding to a particular device. This allows WiFi services to
be loaded immediately as a profile loads, so that operations
that operate on services (like Manager::ConfigureService
and Manager::FindMatchingService) do not need to use a separate
API to find and modify services that are not visible but have
stored configuration associated with them.
This also allows Chrome a somewhat more stabilized service
path to remembered services as they appear and disappear from
view. Another advantage is that this completely regularizes
the relationship between the presence of the service in the
provider's services_ list and its registration with the
manager.
In order to perform late-binding to a WiFi device, we provide
two methods for WiFi services to find a device to call
WiFi::ConnectTo on when the time comes: Firstly, visible
WiFi services (ones with endpoints) can select the device
associated with the most "promising" endpoint. In the case
where we try to connect to a hidden WiFi service before
endpoints appear for it, there is a new method for selecting
a WiFi device from the Manager. In both of these cases only
one WiFi device is selected for the connect request, so this
method is no worse than before in the unlikely case where
there are two WiFi devices, except for the fact that now
there won't be duplicate WiFi services registered in the
Manager.
