Subject: [PATCH] support new special runtime permissions
These are treated as a runtime permission even for legacy apps. They
need to be granted by default for all apps to maintain compatibility.
Ported from 10: 4d5d82f4e2fb9ff68158bf30f3944591bb74dd04
Changes from 10:
- It seems like parts of PackageManagerService#resetUserChangesToRuntimePermissionsAndFlagsLPw
were refactored into PermissionManagerService#resetRuntimePermissionsInternal.
As a result, PackageManagerService is no longer modified.
