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:

+ *
+ * <ul>
+ * <li>Hovering over the button will cause it to gain accessibility focus
+ * <li>Removing the hover pointer while inside the bounds of the button will perform a click action
+ * <li>If long-click is supported, hovering over the button for a longer period of time will switch
+ *     to the long-click action
+ * <li>Moving the hover pointer outside of the bounds of the button will restore to the normal click
+ *     action
