CDD: Concurrent Capture Requirements

In Q the behavior for concurrent access to capture audio
has changed. The previous behavior was "first come, first served."
Once an app started to capture audio, all other apps had no way
to access the audio input until the capturing app stopped.

Android Q imposes a priority scheme that can switch the input
audio stream between apps while they are running. Adding in
requirements so developer expectations are met.

Wi-Fi Easy Connect is a new standard from the Wi-Fi Alliance (WFA).
It is used to provision credentials on devices. The provisioning is
done over a secure channel using separate credentials obtained out-
of-band (e.g. QR code scan). The protocol is a replacement for WPS
(e.g. push-button) which has been determined to be insecure and was
deprecated in Android P.

Android Q supports 2 Easy Connect use-cases:
- Provision credentials on the device from an external source (e.g. AP)
- Provision credentials on IoT devices from the device itself.

CDD: Update Media Center requirements.

This update is necessary for Android Auto and Automotive:
 * Remove C-1-1 as notifications are actually covered by
   https://source.android.com/compatibility/android-cdd#3_8_3_1_presentation_of_notifications
 * Clarify C-1-2 as nobody can display all the metadata that can be provided.
 * Change C-1-3 to display the app icon (icons convey branding better), and
   in more locations for improved content attribution
 * Remove the mention of a particular UI implementation in C-1-4, and
   mention safety regulations.


[For readability]

If device implementations include non voice based applications (the Apps)
that interact with third-party applications through MediaBrowser or
MediaSession, the Apps:
* [C-1-2] MUST clearly display icons obtained via getIconBitmap() or
  getIconUri() and titles obtained via getTitle() as described in
  MediaDescription. May shorten titles to comply with safety regulations
  (e.g. driver distraction).
* [C-1-3] MUST show the third-party application icon whenever displaying
  content provided by this application.
* [C-1-4] MUST allow the user to interact with the entire MediaBrowser
  hierarchy. MAY restrict the access to part of the hierarchy to comply
  with safety regulations (e.g. driver distraction), but MUST NOT give
  preferential treatment based on content or content provider.

If device implementations report android.hardware.telephony,
they MUST have an application that implements InCallService.

InCallService is a critical component for emergency calls and must be

- Update definition of API classifications, as per code changes in Q.
- Add signed config requirement (new feature in Q), and remove the optional

CDD: Restrict permitted BUILD.INCREMENTAL and TAGS

Restrictions to the permitted values of BUILD.INCREMENTAL and TAG
are needed to ensure that they do not contain characters that are
not permitted in the build fingerprint or could be confused with
field separators when parsing the build fingerprint.
Permitting arbitary replacement of invalid characters can lead to
ambiguity in the fingerprint.

CDD: Add SR requirement to display contextual actions in notifications.

In the javadoc for Notification.Action.Builder#setContextual it is not
clear how contextual actions should be displayed (we don't want to lock
down the implementation/UI unnecessarily). With this CDD insertion we
clarify where contextual actions should be shown.
This only applies to handheld devices since the contextual-actions
feature only targets handheld devices.

CDD: Gesture nav requirements for insets & Back

    - New Insets API documentation is developer-facing and does not go
    into depth on how partners should be linking navigation functions to
    the insets communicated. Adding rules for this.
    - Back function is now available as a gesture from the left and
    right edges, which conflicts with app design/components. We're
    accounting for this with clear requirements for Back and other
    system conflicts (system panels).
    - As part of the back opt out APIs, we're enforcing a restriction
    that's only going to be mentioned in documentation and may be
    changed in the future (3-6 months) based on app compatibility.
    Calling this out as part of [C-6-2].
