This reports the total bytes sent and received per interface using
atrace. The totals are taken from the interface counters, rather than
the ringbuffer, since the ring buffer can run out of space.
Interfaces are only reported for interfaces which have packets
sent on them as identified by Nettrace. This helps reduce the cost
significantly for idle periods and on devices with a large number of
interfaces accumulated in the iface stats maps.

The performPoll method in the NetworkStatsService can be called
for many reasons, such as RAT changed events, LinkProperties
changed events, open session method calls, forceUpdate method
calls, etc.
However, the current logging is not sufficient to trace down
the caller of performPoll. This makes it difficult to debug
frequent poll issues or performance problems.
Adding debug log to logcat is not an option, given that
performPoll might run several times per second by system server
callers.
This change adds a reason code to the performPoll method and
a helper class to log performPoll events. This will allow us
to track down the caller of performPoll and better understand
why it is being called frequently or causing performance
problems.
This change also introduces a PollEvent object, which can be
used to put related information in subsequent changes when
logging.
Sample output:
Poll counts per reason:
DUMPSYS: 0
FORCE_UPDATE: 6
GLOBAL_ALERT: 0
NETWORK_STATUS_CHANGED: 3
OPEN_SESSION: 0
PERIODIC: 1
RAT_CHANGED: 1
REG_CALLBACK: 3
REMOVE_UIDS: 0
UPSTREAM_CHANGED: 1

The TTL check and removal of expired services is currently only
performed when a mDNS query is sent. This can result in expired
services remaining in the cache if no queries are sent. To
address this, the remaining TTL will be checked when retrieving
services from the MdnsServiceCache. Add a new flag to enable
the expired services removal feature. This feature will be
implemented in subsequent changes.

This is catched by errorprone where global variables accessing
is not protected by the declared lock, which could lead to a
potiential race problem where these variables are changed but
cannot be seen for the invocation.
This is also safe since:
1. The method called inside mDefaultNetworks is already holding
the same lock.
2. Multiple global variables are protected by this synchronized
block.

Ethernet interface naming is not consistent on Linux. While some USB
ethernet dongles show up as eth0, others might show up as usb0.
This CL changes config_ethernet_iface_regex to "*" which stands for "use
Android version specific default". The default will include both usb\d+
and eth%d named interfaces on Android U+. Android T will continue to
only include eth%d interfaces (note that the "+" is a new addition which
is highly unlikely to have any actual effect, but is more technically
correct).

service-connectivity-mdns-standalone-build-test builds the mDNS
discovery and advertisement implementation against API level 21.
This stops the advertisement code from calling new NsdServiceInfo
public or private APIs which are required by Thread.
This commit removes the mDNS advertisement code from the standalone
build to loose the check given this will never be used by GMS Core.

The transaction id is a number that is used to identify a
specific query packet. But it's not necessary for probing
or announcing services, so the transaction id is not
currently used on advertising when creating a MdnsPacket or
decoding the response to a MdnsPacket. This means that it is not
possible to track which query packets have received
responses. Therefore, store the transaction id so that
it can be used for subsequent query packet changes.

If the flag value is unset or 0, isFeatureEnabled return false and
isFeatureNotChickenedOut return true.
If the flag value is -1 (force disable), both return false.
If the flag value is other values, both query the package version and
return `flagValue <= packageVersion`
Now the only difference is a default behavior when the flag is not set
or 0.
So isFeatureEnabled and isFeatureNotChickenedOut can use the same flag.
This CL also fixes the issue in rollback.
Before this CL, isFeatureNotChickenedOut did not check the module
version and could have a issue if there is a rollback.

This change refactors BundleKey to be a separate struct. This allows
us to do the conversion (e.g. of sport/dport, or icmp fields in the

This change also fixes a bunch of desigated initializer order warnings

The isLegacy field of Nsd metrics should indicate whether the
data was collected from the old backend or not. However, it is
currently only dependent on the ENABLE_PLATFORM_MDNS_BACKEND
compat change value, which is incorrect. This is because the
NsdService always uses the new backend since Android U,
regardless of the compat change value. Therefore, the isLegacy
data should be obtained from each transaction.
