Null pointer exception in FileRotator.java
Sometimes a null pointer exception is thrown when examining files
managed by the file rotator.
The logs from the test show that the Wifi state is changed a large
number of times. On every state change, a write operation is
initiated on the file system. This will eventually result in out
of memory and the call to mBasePath.list() in the maybeRotate(...)
method in FileRotator.java will return null so the iteration will
throw a NullPointerException.

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.

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.

Introduce FileRotator.
Utility that rotates files over time, similar to logrotate. There is
a single "active" file, which is periodically rotated into historical
files, and eventually deleted entirely. Files are stored under a
specific directory with a well-known prefix.
