commit 19aaccdb45521ef1ec19717a22fd4232f66499cd
Author: Reilly Grant <reillyg@chromium.org>

Port //services/device/geolocation to network::SimpleURLLoader

This change migrates users of net::URLFetcher in
//services/device/geolocation to network::SimpleURLLoader. The
asynchronous plumbing for requesting a net::URLRequestContextGetter in
the device service is replaced with simply passing in a
network::SharedURLLoaderFactory.

The tests are migrated from net::TestURLFetcherFactory to
network::TestURLLoaderFactory.
