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

When NDC delivers limitReached() event, NMS re-arms the alert, which
makes another call back to NDC. If NDC already started processing
another call, this causes deadlock.
Fix this by re-arming on a handler thread.

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.

Create a LocalLog class for logging within a service for dumping in dumps.
Use it in the NativeDaemonConnector so we can get some insight into what
is happening in these lockups.

Report non-monotonic NetworkStats through an observer interface
instead of throwing, since those events are still recoverable.

Uses argument escaping inside NativeDaemonConnector, using varargs
to separate boundaries. Also introduces Command object to help build
argument lists.

Perform uniform argument escaping inside NativeDaemonConnector, using
varargs to separate boundaries. Also move to parsed NativeDaemonEvent
instances instead of raw Strings.

Move NTP updates outside locks to avoid blocking ShutdownThread. Add
logging around trim events that remove substantial history. Include
history start in sample events.

Instead of trusting NTP time alone, use the most-conservative of
system clock and NTP.
