Whenever LinkProperties is added/modified/removes, we are updating local
network prefixes for the modified interface/addresses. These prefixes
are used by BPF egress and ingress cgroup hooks to disallow local
network packets if the calling application do not have required
permission.

This change creates an AcceptThread inside ReservedServerOffer which
accepts all incoming L2CAP connections and creates an L2capNetwork for
each of them.
Note that these networks are indistinguishable, so CS will tear all but
the first one down. This is working as intended.
If the L2capNetwork or the AcceptThread encounter any error during
execution, the reserved offer is torn down and the reserving app will
receive an onUnavailable() callback (by virtue of reservation
semantics).

because the Future task sometimes fails to complete on the CF

L2capPacketForwarder forwards packets between an L2CAP BluetoothSocket
and a tun fd.
It uses blocking i/o to do so, since the BluetoothSocket API does not
expose a file descriptor to poll() on.
It remains to be seen whether shutdown() on a tun interface fd is
actually implemented. Currently, the test uses a pair of SOCK_SEQPACKET
sockets which require to be shutdown to interrupt the blocking read.

When setIncludeTestInterfaces(false) is called, any RTM_DELLINK
callback for a testtap interface is ignored, since the interface is no

Change setIncludeTestInterfaces to go through all interfaces, and stop
tracking the ones which are no longer valid. Otherwise, they will
stick around forever (and break subsequent tests).

no internet connection. parseEthernetConfig was updated to provide empty

A NetworkOffer can be updated by registering a new set of capabilities
and score using an already registered NetworkOfferCallback object.
Since reserved offers are guaranteed to never send more than a single
onReserved() callback, they cannot support updating the capabilities
(not to mention that the reservationId is also part of the
capabilities).
This change changes NetworkOffer migration to only allow reserved offers
to update their NetworkScore. If a reserved offer tries to update its
capabilities, the existing offer is removed and the new offer is
silently rejected. This change does not affect regular offers (with
RES_ID_UNSET) nor blanket offers (with RES_ID_MATCH_ALL_RESERVATIONS).

reserveNetwork allows a requestor to initiate the creation of a network
that requires the system to preallocate resources which can then be
advertised by the requestor on or off device in order to help create the
network.
For example, this API will be used to reserve a IP over L2cap server
network, which requires the system to first create a
BluetoothServerSocket and reserve a PSM (i.e. port). This information is
passed back to the requestor via onReserved() callback and subsequently
advertised via a BLE advertisement. The network is established as soon
as the client connects to the advertised PSM, which will trigger a call
to onAvailable(), just like a regular NetworkRequest.
onReserved() callbacks are exclusive to the reserveNetwork API and are
sent when an NetworkOffer is registered that matches the reservation ID
of an existing request. A reserved offer always follows the reservation
request as it is created in direct response. onReserved() can only be
called once. If for some reason the reservation gets cancelled by the
system (i.e. the NetworkOffer is retracted) or cannot be fulfilled,
onUnavailable() is called. It is up to the app to file a new
NetworkRequest when this happens.
An onReserved() callback is not queued, because
a) it cannot be called more than once for the same reservation,
b) it must always be the first callback, and
c) it only gets cancelled by onUnavailable().
This change does not handle NetworkOffer migrations, such as updating
the score, properly. This must be addressed before the feature can ship
as the yieldToBadWifi logic can update the score on all NetworkOffers.

Advertise with a shorter hostname by default (can be disabled via a
chicken bit), instead of "Android_[32 characters]" as the hostname.
This should allow decreasing the size of APF programs necessary for
advertising offload, and make the advertiser compatible with Matter
use-cases. Some Matter implementations (notably CHIP) interpreted
the example in "4.3.1.1. Host Name Construction" of the spec as
if only 16 character hostnames needed to be supported, despite not
following the rule to construct the hostname based on link-layer
addresses.
The hostname changed once in T when migrating from mdnsresponder to the
current advertiser implementation, so changing the format again is
unlikely to create problems, especially since this keeps the "Android_"
prefix.

Instead of having query scheduling time split between MdnsQueryScheduler

This populates the reservationId with the value of the requestId when a
new NetworkRequest is created. Conceptually, the reservationId is not
related to the requestId; however, the requestId fulfills the same
uniqueness requirements that are needed for the reservationId, so it can
just be reused for this purpose.

Timerfd can provide more accurate delayed callbacks than
Handler#postDelayed because it accounts for the time the device
spends in deep sleep. Using timerfd allows for more precise query
