Moved away from BufferedReader, which only reads the first 8KB of
some proc files because it aggresively fills its buffer. Optimized
proc parsing, now double the speed. Tests to cover.
Log when NetworkStats counters roll backwards when subtracting, and
optimizations around findIndex(). When system removes UID, also
remove from last stats snapshot to avoid xt counters from rolling
backwards.

Getting source-based routing working is too risk for this point
in the project but tethering is broken otherwise, so disable
the tethering option if DUN is required until we can get a real
fix in.

Replace TrafficStats calls by reading values from xt_qtaguid kernel
module. To keep BatteryStatsImpl changes lightweight, cache recently
parsed stats. Tracks mobile ifaces from ConnectivityService.
Refactor xt_qtaguid parsing into factory outside of NMS. Add stats
grouping based on UID, and total based on limiting filters like iface
prefix and UID.

When available, use single "iface_stat_all" file instead of reading
values from dozens of files scattered across proc. Tests to verify.

Begin tracking xtables summary of data usage to compare with values
reported from /proc/net/dev. Roll tethering directly into UID stats
to trigger UID stats persisting when crossing threshold.
Include xtables summary and authoritative time in samples.

Change Ife82a8d8 broke IPv6 on wifi. Change I4e3a69ea is
an alternate approach that does not require any framework
changes.

Stop guessing based on the connectivity of the default route and use the correct
v4/v6 proto for your pid.

Watch for changes to telephony network subtype, and update iface
mapping to persist stats under correct type. Update network stats
before removing tethering NAT rules.
Skip recording that would create empty historical buckets. Query UID
stats before iface stats to always skew positive when counters are
actively rolling forward.

When sampling network stats, always use atomic buckets instead of
interpolating. Always poll iface and UID together so we distribute
into buckets equally. Move stale bucket trimming to just before
writing stats.

Use new "gettetherstats" netd command to retrieve statistics for
active tethering connections. Keep tethering poll events separate
from UID poll, even though they end up same historical structures.

* Instead of javaland trying to write commands to
/proc/net/xt_qtaguid/ctrl
use the libcutils/qtaguid.c support via JNI.
* Get rid of tagToKernel() handled by qtaguid library.
Requires libcutils changes from c/132538/

Devices currently delay collecting UID stats during common operations
like global alerts to reduce parsing load. Here we introduce a flag
to always collect UID and iface stats together to aid debugging.

When ifaces change, poll UID stats without persisting, since they
depend on knowing active iface to store correctly. Log dropped UID
stats when iface is unknown. Switch to using flags when calling
performPoll().
Enforce that "idx" values are consistent from xt_qtaguid. Transition
to using Log.wtf() for important checks, mostly around file I/O,
kernel stats parsing, and kernel module control. Increase stats
persist threshold to 2MB to reduce churn.

Only combine /proc/net/dev and xt_qtaguid stats when iface is marked
as active. When inactive, only return xt_qtaguid stats. When iface
is unknown to xt_qtaguid, always pass through /proc/net/dev stats.

Useful for checking if on a wifi-only device.
Similar to asking for NetworkInfo for a network type and checking for
null, though here the intent is explicit.

New broadcast that is dispatched immediately after connectivity
changes have been handled by ConnectivityService, bypassing any
applicable CONNECTIVITY_CHANGE_DELAY.
Also protect CONNECTIVITY_CHANGE broadcasts, since they should only
be sent by system.

When reading network counters, always splice in xt_qtaguid values
to avoid counting backwards. Test to verify.
Remove verbose logging around global alerts, and add dumpsys debug
info for NMS and MDST. Also fix subtle bug around stats persisting
and dumping.
