Original issue's description:
> Geolocation: move from content/browser to device/
>
> This CL:
>
> - moves all of content/browser/geolocation to device/geolocation
> - the public geolocation files in content/common/{browser, public}
>  are also relocated to device/geolocation
> - the geolocation-specific unittests are compiled into
>  (already existing) device_unittests
> - adds new fancy new device/geolocation BUILD.gn  and
>  geolocation.gyp as well
> - makes a component of geolocation (at least for gn) and that forces
>  adding geolocation_export.h (like other //device/ folders).
> - Java Geolocation files are moved as well, and a new
>  geolocation_jni_registrar is added.
> - classes are moved to device namespace.
>
> All paths and include/call sites updated, DEPS, BUILD.gn files,
> gypi files etc.
>
> Some tricks:
> - can't use BrowserThread::CurrentlyOn, etc; instead, the
>  task runner is cached on constructor and used for both thread
>  checking and PostTask()ing (a few unittest and wifi_data_provider*
>  needed that substitution).
> - GeolocationServiceContext is moved to public/cpp so it can
>  be referenced from WebContentsImpl.
> - MockLocationProvider.java is also moved to device/geolocation.

> rationale:device/geolocation depends on dbus and this triggers
> a DEPS presubmit rule -- however, this CL adds no new dependencies,
> hence moving on in the interest of speed (and avoiding more rebases).
