/*
 * The purpose of these functions is to try to get and set the proper
 * file permissions, SELinux contexts, owner, and group so that these
 * files are accessible when we boot up to normal Android via MTP and to
 * file manager apps. During early boot we try to read the contexts and
 * owner / group info from /data/media or from /data/media/0 and store
 * them in static variables. From there, we'll try to set the same
 * contexts, owner, and group information on most files we create during
 * operations like backups, copying the log, and MTP operations.
