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

+/**
+ * A classifier which calculates the variance of differences between successive angles in a stroke.
+ * For each stroke it keeps its last three points. If some successive points are the same, it
+ * ignores the repetitions. If a new point is added, the classifier calculates the angle between the
+ * last three points. After that, it calculates the difference between this angle and the previously
+ * calculated angle. Then it calculates the variance of the differences from a stroke. To the
+ * differences there is artificially added value 0.0 and the difference between the first angle and
+ * PI (angles are in radians). It helps with strokes which have few points and punishes more strokes
+ * which are not smooth.
+ *
+ * <p>This classifier also tries to split the stroke into two parts in the place in which the
+ * biggest angle is. It calculates the angle variance of the two parts and sums them up. The reason
+ * the classifier is doing this, is because some human swipes at the beginning go for a moment in
+ * one direction and then they rapidly change direction for the rest of the stroke (like a tick).
+ * The final result is the minimum of angle variance of the whole stroke and the sum of angle
+ * variances of the two parts split up. The classifier tries the tick option only if the first part
+ * is shorter than the second part.
+ *
+ * <p>Additionally, the classifier classifies the angles as left angles (those angles which value is
+ * in [0.0, PI - ANGLE_DEVIATION) interval), straight angles ([PI - ANGLE_DEVIATION, PI +
+ * ANGLE_DEVIATION] interval) and right angles ((PI + ANGLE_DEVIATION, 2 * PI) interval) and then
+ * calculates the percentage of angles which are in the same direction (straight angles can be left
+ * angels or right angles)
