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().

This patch implements an outstanding TODO in ConnectivityService to add
synchronization over the map of network request ids to network agent
info objects.
This structure is accessed from multiple threads:
- Binder thread on public aidl methods, most notably via
getDefaultNetwork().
- Internal handler.
This leads to many race conditions that can crash the system server and
reboot the phone if getDefaultNetwork() is called on a Binder thread to
service a public ConnectivityManager api while the default network state
is being updated on the internal handler after losing the default
network.

VpnTest was broken earlier due to a change to always-on VPN
notifications. This CL adds the corresponding mocks to the unit test to
fix it.

This patch defines a new WakeupStats event in ipconnectivity.proto and
populates these events from the NFLOG wakeup events stored in
NetdEventListenerService.
There is one WakeupStats object per known interface on which ingress
packets arrive and may wake the system up.
Example from $ adb shell dumpsys connmetrics list:
...
WakeupStats(wlan0, total: 58, root: 0, system: 3, apps: 38, non-apps: 0, unrouted: 17, 6111s)
WakeupEvent(13:36:31.686, iface wlan0, uid -1)
WakeupEvent(13:38:50.846, iface wlan0, uid -1)
WakeupEvent(13:39:16.676, iface wlan0, uid 10065)
WakeupEvent(13:40:32.144, iface wlan0, uid 1000)
WakeupEvent(13:40:35.827, iface wlan0, uid 1000)
WakeupEvent(13:40:47.913, iface wlan0, uid 10004)
WakeupEvent(13:40:52.622, iface wlan0, uid 10014)
WakeupEvent(13:41:06.036, iface wlan0, uid 10004)

This patch stores NFLOG packet wakeup events sent by Netd to the system
server into a ring buffer inside NetdEventListenerService. The content
of this buffer is accessible by $ dumpsys connmetrics or $ dumpsys
connmetrics list, and is added to bug reports.
The wakeup event buffer stores currently uid and timestamps.
