The tc police filter attaches to the clsact qdisc, so the rate limit
cannot be enabled before the qdisc is added to the interface.
The clsact qdisc is added as part of INetd#networkAddInterface, which is
called from inside updateLinkProperties.

Currently, there are two EVENT_NETWORK_TESTED message types in
ConnectivityService. One is used by the ConnectivityService
handler to process validation results, and one is used by
ConnectivityDiagnosticsHandler to send connectivity reports.
The two messages have different contents so it is confusing that
they have the same integer and the same name. Rename the second
one to CMD_SEND_CONNECTIVITY_REPORT.

All NetworkMonitor messages contain the netId of the source
NetworkMonitor. But the netId is in various places in the
message. It's most frequently in arg2, but sometimes it's boxed
into an Integer in obj, and sometimes it's in another object.
Always pass the netId into arg2. This allows us to write
common code at the beginning of the function that extracts the
netId and nai, and performs common actions on all messages.

Some system components like VPN need to know how to redact
NetworkCapabilities & LinkProperties that they received from
the system but need to send to third-party applications with
less privilege than themselves. To make sure the redaction is
consistent, expose system API methods to do it that are wired
to the same redaction code used by ConnectivityService.

Adds ingress rate limiting functionality to ConnectivityService. The tc
rate limit is installed before we tell netd about the interface, and
removed after the network is removed from netd. When the setting
changes, the old rate limit needs to be removed before a new one can be
added (unfortunately, we cannot use NLM_F_REPLACE when configuring the
tc-police filter).
Currently, this functionality is always enabled, but may or may not work
based on kernel support.

Reason for revert:
- The reverted CL fixes a bootloop on Fi devices and must be submitted again for droidfood stability purposes.
- It's not clear whether the revert actually fixes the test that prompted it.

NetworkAgents send NetworkCapabilities to ConnectivityService but
there are limits to what exactly they can send. Going forward,
some of these checks will have to happen on the handler thread,
which is already the case when an agent updates its capabilities,
but not upon registration.
This patches moves the sanitization on the handler thread, after
the network monitor is created for a network agent.
Before this patch, upon registration of a new agent, the binder
thread would copy and sanitize the capabilities, then store them
in nai.networkCapabilities. It would store the original caps from
the agent in the NAI, mix in what is known from the network info,
process the LinkProperties, and then proceed to create the
network monitor, but not yet store the NAI in the internal
structures because its registration is not finalized, so other
methods should not see it yet. After the monitor is created in
the network stack process, the NAI is stored in the internal
structures which publishes it for all methods to see. After
that is done, the NAI calls to the network monitor to warn it
that it's registered, what its capabilities are, and that it's
time to start validation if applicable.
With this patch, the validation no longer happens on the binder
thread. Instead, the binder thread stores the capabilities and
link properties as is, before sanitization, in the NAI. This is
fine because no other method can access these until the
registration completes upon notification that the monitor has
been created ; this agent is only stored in the network monitor
callbacks in a self-destructing object precisely to make sure
that's the case.
When the monitor is created and CS receives notification of the
same, it will sanitize the capabilities before adding the NAI
to the internal structures, to protect the invariant that the
un-sanitized capabilities inside the NAI can't ever be seen by
any other method. After that's done, it will call to the
monitor to start validation as usual.

The code cannot work before T because before T the tethering
module can only load BPF programs/maps into /sys/fs/tethering/bpf
and the system server cannot access that directory.
Additionally, this is causing unit tests to fail on pre-T devices
because on those devices the seccomp filter blocks the bpf
syscall from apps (including Java tests).
