Migrate network stats from removed users.
When a user is removed, migrate all network stats belonging to that
user into special UID_REMOVED bucket. Also removes those stats from
kernel to avoid double-counting if another user is created.

Recover from Throwable in FileRotator, dump.
In rewriteSingle(), catch Throwable to rollback to backup file,
instead of just IOException. Also add dumpAll() to pack up contents
for later debugging, and use it when encountering bad stats.

Reduce persist threshold for lower warning/limit.
Default is 2MB persist threshold, but even that can be substantial
for devices on 100MB/month plans. This change gradually reduces the
persist threshold up to 8x lower (256kb outstanding) based on lowest
active policy.

Begin collecting xtables iface counters.
Add method to parse new iface_stat_fmt proc stats, or return null
when kernel support is unavailable. Add test and remove older, unused
parsing code. Create new "xt" recorder to persist the new xtables
counters when available.
Add SSID support to NetworkIdentity to fix policy tests.

INetworkStatsSession with lifecycle for caching.
Users outside system_server now explicitly communicate their
lifecycle, which keeps a strong-reference chain to any fully loaded
NetworkStatsCollection histories.

Send broadcast when changing restrict background.
When changing global restrict background status, send connectivity
change broadcast, since it radically changes DISCONNECTED/BLOCKED
status system-wide.
Also reduce verbose stats logging.

Move network stats to FileRotator pattern.
Split existing network stats into two separate classes: a recorder
which generates historical data based on periodic counter snapshots,
and a collection of historical data with persistance logic.
Recorder keeps a pending history in memory until outstanding data
crosses a specific threshold. Persisting is handled through a given
FileRotator. This pattern significantly reduces disk churn and
memory overhead. Separate UID data from UID tag data, enabling a
shorter rotation cycle. Migrate existing stats into new structure.
Remove "xt" stats until iptables hooks are ready. Avoid consuming
Entry values when recording into NetworkStatsHistory. Assign
operation counts to default route interface.
Introduce "Rewriter" interface in FileRotator with methods to enable
rewriteAll(). Introduce IndentingPrintWriter to handle indenting in
dump() methods.
