With b/152655547, all aidl_interface modules are considered as stable
unless it is explicitly with "unstable: true". This change marks the
aidl_interface that are not used across updatable module bounraries
as unstable, so that the build system does not run the API
dumping/checking on them.

This is used to fix the race when quickly OFF/ON wifi tethering.
When IpServer is started/stopped, there is callback update tethering
interface status. Before this change, IpServer is stopped when wifi
ap is disabling. Then the next startTethering may fail in wifi because
wifi is in disabling state.
Error pattern: WifiService: Tethering is already active.
No unitest for this CL but it fixed the CtsTetheringTest flakty rate
than around 30% to 0 for more than 100 runs.

These events don't have MAC addresses, so the code attempts to
create an Ipv6ForwardingRule with a null MAC address. This
crashes when attempting to get the raw MAC address bytes to send
to netd in the TetherOffloadRuleParcel.

This was not caught by unit tests because the test exercise this
code path in a way that is not correct (by sending RTM_DELNEIGH
and NUD_FAILED events with MAC addresses). Fix the unit tests to
properly pass in null MAC addresses for these events.

With b/150232615, we will need an explicit value set for the exported

changing for S+. This change adds the value reflecting the previous
default to the manifest.
