Now stores tags other than TAG_NONE (0x0), which are useful for app debugging. Combine UID and tag together into single long key, and expose tag data through AIDL when requested. Change NMS to track TAG_NONE as total UID traffic, matching the kernel definition. Added TAG_MAX_HISTORY to control how long tag-granularity statistics are stored; overall UID usage is still kept for UID_MAX_HISTORY. Fix bug to trim NetworkStatsHistory outside normal polling loops to catch non-active networks and UIDs. Test to verify UID and tag packing, and to verify that UID traffic on two networks are combined to match MOBILE_ALL template. Change-Id: If0e039416d9e7f63b1a39e04cddfb1133b5a78ee
