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.

After adding the xt_bpf module and ifaceStatsMap, eBPF tool can now
support reading per interface data. So networkStatsFactory should move
away from parsing proc/net/dev and use the eBPF map stats instead.

In order to properly support EOPNOTSUPP this CL
applies a consistent approach to handling Exceptions.
Hereafter, all exceptions that aren't of a special
method-specific type (such as SpiUnavailableException)
will all be returned to the calling process unchanged.
At the API call site, the ServiceSpecificException,
which is really an Errno, will be inspected and either
converted to an unchecked exception for types we know,
or it will be converted to an IOException in cases where
that method can return a checked exception. In cases
where we do not expect an errno, we will simply throw
a generic RuntimeException. This means all API calls
will now properly throw UnsupportedOperationException
and may be CTS tested accordingly.

Collecting network statistics is pretty heavy, which is why we're
throttling callers. However, to keep CTS running fast, we provide a
way for tests to force a poll event, instead of making them wait for
the throttle timeout.

We've seen devices where heavy communication between "system_server"
and the "phone" process can exhuast Binder threads, especially when
calling while holding locks. To mitigate this, we now interact with
the "phone" process before acquiring any locks.
Update our internal data structures either when we see a connectivity
change, or when SubscriptionManager tells us something changed.
Fix bug in resolveSubscriptionPlan() that always picked the 0'th
SubscriptionPlan instead of looking for the currently active plan;
we now use the same logic for both NSS and NPMS.

These trace points surround areas of heavy lifting to help us debug
code that might be taking longer than expected. (For example, slow
getting data from eBPF, slow recording into data structures, slow
writing to disk, or slow evaluating policy.)

Someone started setting mSystemReady too early, when we really want
to know SystemServer's real ready state. Add a variable to track
that, and don't process broadcasts until that's set.

Per email feedback, we should be using "noteOp" instead of "checkOp"
when testing if caller holds OP_GET_USAGE_STATS, so that we record
that caller used the operation.

Hide the tunnel mode of the IpSec API because
there is a disincentive to launch it without
a supported customer use case. That use case,
IWLAN is having its APIs hidden, so we should
hide these as well to avoid constraining future
implementation.
Also, due to issues with the lifetime of the NATT
management object, this API needs to be hidden
until such time as the lifetime of the Keepalive
can be handled independently of the lifetime of
a Transform.
