The current implementation of global proxy is dead,
and it will be removed completely in separate changes.

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.

When recording data usage, measure the actual active time, since
buckets can be quite long. Offer incrementOperationCount() version
that reads thread stats tag for caller. Rethrow any NPE as ISE
during stats parsing, which callers already handle.

Instead of polling every 15 minutes, register for alerts that trigger
when system-wide traffic passes a threshold. Still mixed with polling
to persist UID stats, but relaxed to 30 minutes. Currently watches
for every 512kB.
Make persistence decision separately for network versus UID, and use
total delta bytes when making decision. Use light bootstrap during
systemReady() instead of heavy poll, which had been force-loading all
UID data unnecessarily.
