Update dialer sources.

Test: Built package and system image.

This change clobbers the old source, and is an export
from an internal Google repository.

The internal repository was forked form Android in March,
and this change includes modifications since then, to
near the v8 release.

Since the fork, we've moved code from monolithic to independent modules. In addition,
we've switched to Blaze/Bazel as the build sysetm. This export, however, still uses make.

New dependencies have been added:
- Dagger
- Auto-Value
- Glide
- Libshortcutbadger

Going forward, development will still be in Google3, and the Gerrit release
will become an automated export, with the next drop happening in ~ two weeks.

Android.mk includes local modifications from ToT.

Abridged changelog:

+/**
+ * This class is used to detect the country where the user is. It is a simplified version of the
+ * country detector service in the framework. The sources of country location are queried in the
+ * following order of reliability:
+ *
+ * <ul>
+ * <li>Mobile network
+ * <li>Location manager
+ * <li>SIM's country
+ * <li>User's default locale
+ * </ul>
+ *
+ * As far as possible this class tries to replicate the behavior of the system's country detector
+ * service: 1) Order in priority of sources of country location 2) Mobile network information
+ * provided by CDMA phones is ignored 3) Location information is updated every 12 hours (instead of
+ * 24 hours in the system) 4) Location updates only uses the {@link
+ * LocationManager#PASSIVE_PROVIDER} to avoid active use of the GPS 5) If a location is successfully
+ * obtained and geocoded, we never fall back to use of the SIM's country (for the system, the
+ * fallback never happens without a reboot) 6) Location is not used if the device does not implement
+ * a {@link android.location.Geocoder}
