Non-linear font scaling is meant to improve readability at larger font
scales: larger fonts will scale up more slowly than smaller fonts, so we
don't get ridiculously huge fonts that don't fit on the screen.
The thinking here is that large fonts are already big enough to read,
but we still want to scale them slightly to preserve the visual
hierarchy when compared to smaller fonts.
The FontScaleConverter converts SP dimensions to DP, to be used in
TypedValue.applyDimension() which will affect most TextViews and font
sizes automatically.
For now, all the lookup tables are hardcoded. A follow-up CL will make
them configurable via XML. The hardcoded arrays also default to a linear
curve, as to not break any tests. The non-linear curve will come in a
follow-up CL, to make it easier to roll-back if requested.
Also included is some Javascript to generate the hardcoded arrays, which
can later be manually tweaked and optimized.
Test: unit, CTS, and manual:
1. Run `adb shell settings put system font_scale 2.0`
2. Check different apps to see if they are readable.

This change will block the installation (but not the execution)
of apps that do not meet the minimum target sdk version.
The intention is to improve security and privacy by blocking low
target sdk apps as malware can target older sdk versions to avoid
the enforcement of new API behavior.
This change is fenced off by a feature flag. The plan is to
progressively ramp up the min_installable_target_sdk version
up to version 23 for Android U.

This CL addes a new API to PackageInstaller.SessionParams that can be
used to skip the app enable step during the package install flow. This
can be used by installers to keep the app's existing enabled state
after a upgrade instead of setting it to enabled by default.
This also corrects the variable userId used in the enable step to
currentUserId that was preventing it from enabling the app when
installed for all users.

- orSelf: signifies that this method checks if the calling process OR
the current process has the permission
- anyOf: signifies that if this method checks multiple permissions,
the check passes if ANY ONE of the permissions is granted
- value (default parameter): a hard coded list of permissions that this method checks.
This parameter is useful for static analysis, where the implementation
of some @PermissionMethod may not be visible across library
boundaries. A good example of this is
NetworkStack#checkNetworkStackPermission, which is a source in
framework-minus-apex, but is used from services.core.unboosted. Since
it passes straight into a helper which checks the actual permissions,
it's not possible for lint running on services.core.unboosted to see
which permissions are checked.

WearableSensing framework APIs are intended to be used to interact and
manage the WearableSensingService. The WearableSensingService provides
an isolated service environment for an application to provide a remote
data stream to and run sensing workloads on the data stream. Clients
that want to use this API must hold the permission
MANAGE_WEARABLE_SENSING_SERVICE. The permission protection level is signature|privledged.
API overview: go/wearable-sensing-api
Design doc: go/trusted-glasses
A follow up CL will implement the integration between
WearableSensingService and AmbientContextManager. A subsequent follow up
will also add unit and cts testing.

All foreground services are required to declare a type now, or
it'll get a ForegroundServiceTypeNotAllowedException if the app's
target SDK level is Android U or later.
Upon starting the foreground service, the app is required to
have been granted with the proper permissions which are required
by the foreground service types it's starting with.
Deprecated the type "none" and "dataSync", introduced new types:
"heath", "remoteMessaging", "systemExempted" and "specialUse".
The implementation of the enforcement will be in a follow up CL.

This adds an API to determine if the context user is the designated
main user on the device. This user may have access to features which
are limited to a single user on the device.
In Android U, this will be the first user to go through setup.
On regular devices, this will be the system user, but on devices in
No Primary User / Headless System User Mode, it will be a different
user.
The isPrimaryUser System API is confusing because it actually always
returns the system user, even in headless mode. That API is deprecated
in this change.
On devices that are upgrading, if they are non-headless, the system user
will be the main user. If they are headless, the full user with the
earliest creation date will be given the flag.
