This is no longer necessary as all the methods that take it are
running on on the handler thread, either in Tethering itself or
on the state machine thread in IpServer, which runs on the same
thread as Tethering.
Specifically:
- interfaceStatusChanged, interfaceAdded, interfaceRemoved,
interfaceLinkStateChanged: run from mNetdCallback, which always
posts them to mHandler.
- setWifiTethering: only called by enableTetheringInternal, which
is called by the following:
- startTethering, stopTethering: via lambda posted to mHandler
- IpServerCallback#requestEnableTethering: called by IpServer
while processing a command.
- setEthernetTethering: only called by enableTetheringInternal.
- EthernetCallback: runs on mExecutor, which posts to mHandler.
- getLastTetherError: only used by the test. Renamed to
getLastErrorForTest to ensure no other callers.
- sendTetherStateChangedBroadcast: called only by
notifyInterfaceStateChange, which is called only by
- IpServerCallback#updateInterfaceState, which is called only
by sendInterfaceState, which is called by various IpServer
state enter methods.
- notifyLinkPropertiesChanged: called only by
IpServerCallback#updateLinkProperties, which is only called by
IpServer#sendLinkProperties, which is only called by:
- Code that processes CMD_IPV6_TETHER_UPDATE
- IpServer#handleNewPrefixRequest: only called when processing
CMD_NEW_PREFIX_REQUEST.
- IpServer#sendInterfaceState (see above)
- handleWifiApAction, handleWifiP2pAction: only called by
mStateReceiver, which runs on the handler thread
- tether(String, int): called by:
- tether(String, IIntResultListener): posted to mHandler
- changeInterfaceState: called by:
- EthernetCallback (see above)
- enableWifiIpServingLocked: called by handleWifiApAction and
handleWifiP2pAction (see above)
- tetherMatchingInterfaces: only called by handleUsbAction,
which is run from mStateReceiver on the handler thread.
- untether(String): called by:
- untether(String, IIntResultListener): posted to mHandler
- changeInterfaceState (see above)
- setUsbTethering: called by:
- setUsbTethering(boolean, IIntResultListener): posted to mHandler
- enableTetheringInternal (see above)
- setNcmTethering: called by enableTetheringInternal (see above)
- getTetheredIfaces: called only by TetheringTest. Renamed to
getTetheredIfacesForTest to ensure no other callers.
- getErroredIfaces: unused, deleted in this CL
- getTetheredIfaces: called by:
- isTetheringActive: called by onUserRestrictionsChanged, which
is only called by mStateReceiver
- TetheringTest
- dump(): changed to run on handler thread
- upstreamWanted: called by
- TetherModeAliveState#enter
- TetherModeAliveState#updateUpstreamWanted, which is called
only by TetherModeAliveState#processMessage.

These tests are currently broken due to what appears to be an
upstream regression affecting 5.10 kernels, and are causing
all networking CLs to fail presubmit.
Skip them in presubmit until the regression is fixed. The tests
will still fail when run manually or in postsubmit.

This allows the coverage tests to manually trigger native coverage
collection, as a workaround for collection not being triggered
automatically by the coverage infrastructure.

The type of ConnectivityManager#PRIVATE_DNS_MODE_OPPORTUNISTIC
has changed from String to int, but the String definition is still
needed to update to Settings.Global.PRIVATE_DNS_MODE, so the
simplest way is to define one locally.

Ignore-AOSP-First: In the same TOPIC, there is a merge conflict in
DevicePolicyManagerService.java in the internal branch, so it's needed
to merge the code into internal branch to fix the merge conflict.
Add ACCESS_NETWORK_STATE to Tethering CTS because tests call to
EthernetManager#isAvailable() which is enforcing permission check
now. Without ACCESS_NETWORK_STATE, some tests will fail by lack
of permission.
