The system server is controlling the tcp buffer now by writing to
/sys/kernel/ipv4/tcp_{rmem,wmem}_{min,def,max}. Those files are
basically the same as /proc/sys/net/ipv4/tcp_{rmem,wmem} except those
latter ones contain all three values in one file. Netd can directly write
to those files so we no longer need to depend on these android specific
files.

When using xt_qtaguid to count per uid stats,
NetworkStatsService needs to adjust the 464xlat traffic since
iptables module would double count for ipv4 and ipv6 packet.
But for eBPF, the per uid stats is collected in a different
hook, so the adjustment on root uid would only be needed in tx
direction.

Currently, if VPN lockdown is disabled, the blocking judgement

This will improve the user experience on Android TV devices,

In addition when connecting adb to the device by ethernet
for cts, wifi will not connect, causing lots of tests to fail.

Allow VPN apps to lookup the UID owner of a network connection.
Requires specifying the:
- IP address and port for both the source and destination of a TCP
connection.
- IP address and port for either source and destination or just
source for a UDP connection.
Only TCP and UDP protocols are supported. Only connections for UIDs
that apply to the calling VPN app will be resolved. This is intended
to replace direct app access to /proc/net/{tcp,tcp6,udp,udp6}.
The implementation uses netlink inet_diag sockets[1] to perform
the lookup on TCP sockets as well as UDP sockets when supported
(kernel has CONFIG_INET_UDP_DIAG=y).

Rename TetherInterfaceStateMachine to IpServer. IControlsTethering
is folded into IpServer.Callback and some of the dependencies in

IpServer into the Tethering layer above it

This change makes all requestIDs use the UID of the creator, ensuring
that rekeys always use the same requestID. This also has the nice

This matches previous behavior, and there could be situations where
another server on the network would be configured to reply to such
requests, so not replying is better than sending NAKs as done now.
Also refactoring requests in DhcpLeaseRepositoryTest and replacing some
INETADDR_UNSPEC usages for giaddr with INET4_ANY (giaddr is a BOOTP
field and can't be unspecified, only empty).
Test: Following DhcpServerTest.py regression tests pass:
