/**

 * Calls from the system into the permission controller.

 *

 * All methods are called async beside the backup related method. For these we force to use the

 * async-task single thread executor so that multiple parallel backups don't override the delayed

 * the backup state racily.

 * All reading methods are called async, and all writing method are called on the AsyncTask single

 * thread executor so that multiple writes won't override each other concurrently.
