In order to support rollbacks, the ethernet ipconfig file needs to be
written to the data apex's data directory. We still need to support
reading from the legacy location to be backwards compatible.
If the apex file path already exists, then read the IP configuration
from there directly, otherwise, check if the legacy file path exists,
if yes, read the legacy IP configuration and copy it to the new apex
file path.
Support for default IpConfiguration is also being removed in this CL.
The default IpConfiguration (configuration entry for interface "0")
was a way to transition from supporting a single interface to
supporting multiple interfaces and was introduced in P. Every device
that has used such a configuration and has connected to an ethernet
network since upgrading to P+ has already removed the "0" config and
has assigned it to the first interface (probably "eth0"). There has
never been an API to set this, but if someone wanted to install a
default IpConfiguration, they could just configure "eth0" instead.

Adds a global listener that is used to wait for an interface to show up
in EthernetTracker when it is newly created. This prevents races when
the interface is used directly after creation.
This test should fix the testCallback flakes.

In practice this doesn't actually really matter, since older versions
of the bpfloader won't even look in the relevant directories:
BpfLoader v0.9 is the first one that looks into
'/apex/com.android.tethering/etc/bpf/net_shared',
but it is only v0.12 that pins the resulting programs and maps
correctly into
/sys/fs/bpf/net_shared/
hence the annotations for block/clatd/dscp_policy.
BpfLoader v0.13 is the first one that looks into
'/apex/com.android.tethering/etc/bpf/netd_shared'
subdirectory and pins into
/sys/fs/bpf/netd_shared/
hence the annotation for netd.
But it's best to explicitly document the intent.
Note that in practice the mainline module will fail spectacularly
on a T OS if it can't find the programs and maps
(presumably due to the bpfloader being too old)
but will work on S even though the bpfloader there is much older,
because these programs/maps are not required on pre-T OS.
This change is thus really only documentation.

(out of current /sys/fs/bpf/net_shared/...)
This will allow genfscon regexp changes in a followup selinux commit.
Note that this has a hard dependency on system/bpf change
'bpfloader: add support for netd_shared and net_private subdirs'
which also bumps bpfloader to v0.13.
This was merged May 12, 2022 (into both aosp/master and tm-dev)
and it is in Android T starting with Beta 3 release.
This isn't really an issue since amusingly T Beta 2 is already
incompatible with current mainline releases due to the snap
reverting a previous required bpfloader system/bpf change:
move net_shared bpf programs into net_shared subdirectory
See: http://b/232050459#comment14
So this doesn't break T Beta1/2, since they already don't work,
and Beta3 will work.
