IpReachabilityMonitor (and IpNeighborMonitor) are only accessed from
the IpManager StateMachine's thread. Consequently lots of locking can
now be removed.
Additionally:
- rename BlockingSocketReader to PacketReader
- incorporate IpReachabilityMonitor output in dump()
Test: as follows
- runtest frameworks-net passes
- "adb shell ip neigh change <address> dev wlan0 nud failed"
triggers wifi to disconnect

Improve the Validation of IpSecAlgorithm by
explicitly checking the length in addition to
the truncation length (previously an oversight).
In addition, we now check the lengths during
un-parceling, which will catch someone maliciously
manually building a parcel and passing it, bypassing
the checks in the constructor.

This patch does some light refactoring in MacAddress to prepare for
exposing MacAddress in the public api:
- documention is improved
- some method names are renamed
- a toSafeString method is added
- a padding bug in the conversion methods outputting strings for
mac addresses is fixed

Also removes netId field from inside NetworkEvent and stop populating
the network_id field of the NetworkEvent field, deprecating it.

Android Instant Apps in its current iteration does not use namespaces,
but due to limitations on the Android resource runtime, needs to make
it look like it does.
This is due to a bug that treats any package ID that's not 0x01 or 0x7F
as a shared library. Shared libraries require unique package names.
As a workaround, and since Android Instant Apps can not have a feature
depend on another feature, we can alter the resource package name of a
feature split just before writing it out to disk. This avoids using a
unique package name while linking, thereby avoiding namespace issues.

This patch introduces a helper ApfConfiguration class for passing filter
parameters to the constructor of ApfFilter. The benefits are:
- less parameter boilerplate across IpManager, ApfFilter, ApfTest
- easier to add more parameters in the future (useful for hardware
counters options and further gservices configurable options)
There is no functional changes otherwise.

This patch changes instrumentation of default networks and default
network events:
- stop logging events for default network transitions,
but instead consistently log one event per continuous segment
when one given network was the default, including logging an
event for when there is no default network.
- keep a separate rolling buffer of DefaultNetworkEvent for
dumpsys and bug reports.
These changes allow to simplify post aggregation of default network
event metrics by removing any need to do time series processing.
Instead, metrics and counters can be implemented withouth any ambiguity
by following the recipe:
% of x = sum(duration | x = true) / sum (all durations)
where x can be various conditions such as:
- the default network was validated
- the default network was WiFi
- the default network was IPv6
- there was no default network
- ...
Most importantly, this new logging scheme allows to measure much more
reliably:
- the % of the time that a device had Internet, in the sense that the
default network was validated.
- the time transitions between default networks, keyed by previous and
new transports/link layer, which allows to derive wakelock durations
and wakelock power costs from default network switches.
This patch also simplifies the dumpsys interface of the connmetrics
service and reduces the commands to three:
- "flush" for metrics upload.
- "proto" for printing buffered event in text proto format.
- "list" for listing all events and statistics.
