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:

Bug fixes
● Not able to mute, add a call when using Phone app in multiwindow mode
● Double tap on keypad triggering multiple key and tones
● Reported spam numbers not showing as spam in the call log
● Crash when user tries to block number while Phone app is not set as default
● Crash when user picks a number from search auto-complete list

Visual Voicemail (VVM) improvements
● Share Voicemail audio via standard exporting mechanisms that support file attachment
(email, MMS, etc.)
● Make phone number, email and web sites in VVM transcript clickable
● Set PIN before declining VVM Terms of Service {Carrier}
● Set client type for outbound visual voicemail SMS {Carrier}

New incoming call and incall UI on older devices
(Android M)
● Updated Phone app icon
● New incall UI (large buttons, button labels)
● New and animated Answer/Reject gestures

Accessibility
● Add custom answer/decline call buttons on answer screen for touch exploration
accessibility services
● Increase size of touch target
● Add verbal feedback when a Voicemail fails to load
● Fix pressing of Phone buttons while in a phone call using Switch Access
● Fix selecting and opening contacts in talkback mode
● Split focus for ‘Learn More’ link in caller id & spam to help distinguish similar text

Other
● Backup & Restore for App Preferences
● Prompt user to enable Wi-Fi calling if the call ends due to out of service and Wi-Fi is
connected
● Rename “Dialpad” to “Keypad”
● Show "Private number" for restricted calls
● Delete unused items (vcard, add contact, call history) from Phone menu
