This is a temporary hack to workaround the inability of current
kernel's ebpf bpf_skb_change_mode() function to prefix a 14-byte
ethernet header on to a packet without going over the upstream
(source, rawip) interface's mtu *before* we bpf_redirect() to
the downstream (destination, ethernet) interface.

The callbacks are fired when the list of connected clients or their IP
addresses / hostname change.

TetheringUtil JNI is too big that it statically linking hidl and its
dependency library. To remove these static libraries, calling hidl in java
directly instead of using JNI.

Ethernet tethering can be started via
startTethering(TETHERING_ETHERNET).
Test: flashed, enabled ethernet tethering, verified internet access on
downstream.

(cherry-pick with conflicts in test-current.txt)
When leaving a group, all information are erased and no group interface
is passed to tethering service.
For separate group interface, tethering could be stopped
on p2p group interface removed. For shared group interface,
i.e. management interface and group interface share one
interface, ex. p2p0, tethering has no chance to be stopped since management
interface won't be removed after leaving a group.

Currently NetworkStatsService is notified when downstream is
updated. However, it seems unnecessary given that tether stats
is persist since boot, and there is no any upstream change when
downstream is changed.

Replace some ConnectivityManager constants as TetheringManager inside
tethering module. No API change, will have follow up CL to delete
@hide tethering constants in ConnectivityManager and replace caller
to using TetheringManager.

- Using INetd to communicate with netd directly instead of using
NetworkManagementService which is a wrapper of INetd and don't have plan
to be updatable.
- Also replace InterfaceConfiguration by InterfaceController.
- Remove redundant interface flags. Only set interface up/down flag to
netd because netd only use these two flags for INetd#interfaceSetCfg.
- Note that tethering still use NetworkManagementService
to register tethering stats provider and it would also be replaced with
other way in follow up change.

Move tethering out of ConnectivityService. All client would
use TetheringManager to talk with TetheringService directly.

Now tethering would be run in dedicated service.
TetheringManager is the interface used to communicate with
TetheringService. The new call flow would be: ConnectivityManager
-> ConnectivityService -> TetheringManager -> TetheringService.
Note: the return value of #tether(), #untether() and #setUsbTethering()
APIs would always be no error. Client can use #getLastTetherError()
or #getTetheredIfaces or listen tether state change to check
status of corresponding interface.
