This change corrects the VpnProfile's maxMtu defaults to match that of
the Ikev2VpnProfile. 1400 is too high as a default, and Settings will
run into an issue here quite often.

(cherry picked from commit d0a44f49df01a1aefa505ee90c9806dee135b4e4)
This commit adds the fields required to support IKEv2/IPsec VPNs. Other
fields will be reused where possible.

In order to notify netd to swap eBPF maps before pulling the
networkStats from eBPF maps, NetworkStatsFactory need to use the
NetdServices to issue binder calls. So it need to be moved from
framework/base/core to framework/base/service since object in
framework/base/core cannot get any system services. This change is also
necessary for setting up a lock inside NetworkStatsFactory to prevent
racing between two netstats caller since the lock need to be hold before
netd trigger the map swap.
Also fix the compile problem caused by moving the NetworkStatsFactory
and the related tests. Rename the packages and the jni functions to a
more proper name.

Currently, 464xlat counts its ipv6 tx traffic into root uid.
When user is making ipv4 upload over ipv6-only network, ipv4
tx traffic may sometimes be counted faster then ipv6 tx
traffic.
Thus, NetworkStatsService may detect non-monotonic values due
to 464xlat adjustment.
So the solution is that: for clatd, make ipv6 tx traffic counts
into clat uid, and then ignore it in the framework side.

Test: 1. manually verify clatd traffic on clat uid.

With the new xt_bpf support for iface stats. We no longer need to parse
the per interface stats from /proc/net/dev. And since the old xt_qtaguid
code path also not depend on it, we can completly remove that helper
function since no caller is depending on it now.

Useful for clients such as BatteryStats which currently rely
on NetworkStatsFactory. Data at that stage is incomplete as
it does not account for tethering, VT data and corresponding
464xlat corrections.
Test: runtest frameworks-net, CTS tests pass.

If the qtaguid proc file is no longer exist, the device is running new
eBPF module to do traffic accounting. So the NetworkStatsFactory need to
use the proc/net/dev interface to get the per interface traffic stats
summary. Also, adding a test to verify the helper function work properly

Add the native method used to read the detail information of network
stats from bpf maps. The native method of NetworkStatsFactory should
choose the correct implementation to get the stats detail depending on
the kernel version. Currently the bpf result is printed as a reference
and the actual behavior of NetworkStatsFactory should not change.
Test: NetworkStatsFactory related cts test should not fail.

This allows us to maintain NetworkStats entries that track
whether the traffic was on the default network.
At the moment, the stats collection code always passes in
DEFAULT_NETWORK_NO. However, this value is a no-op, since it is
not persisted to disk. Only the ident, the uid/set/tag, and the
packet/byte/operation counters are persisted.
A future change will add defaultNetwork to the ident and start
persisting it.

This patch takes out the ring buffer array added for NFLOG wakeup packet
events logging and extract it into its own class for reuse. This new
RingBuffer class has the two minimal useful functions append() and
toArray().

For 464xlat scenarios on IPv6 networks, the clatd interface setup
introduces double counting of apps ipv4 traffic. NetworkStatsFactory was
accounting for this on the tx path, but not on the rx path. Also it did
not accounted for the 20 bytes added by the IPv6 header.
This patch subtract correctly the rx and tx traffic from the root uid on
the underlying interface, and also adds correctly the 20 bytes cost per
packet on the stacked interface for 464xlat traffic.
Test: added several new unit tests, based on synthetic data and real
data also.

This groups them together with the rest of the networking unit
tests. It also speeds up compile/test cycles ("runtest -x" of one
file goes from 1m15s to 30s).
