Subject: Update Dialer source to latest internal Google revision.

Previously, Android's Dialer app was developed in an internal Google
source control system and only exported to public during AOSP drops.

The Dialer team is now switching to a public development model similar
to the telephony team.

This CL represents all internal Google changes that were committed to
Dialer between the public O release and today's tip of tree on internal
master. This CL squashes those changes into a single commit.
In subsequent changes, changes will be exported on a per-commit basis.

Test: make, flash install, run
