flags.aconfig for android networking is under
packages/modules/Connectivity.
But, currently, mainline code should not read trunk stable flag.
To avoid confusion, this CL moves flags.aconfig to platform.

A helper class to *read* java BpfMaps. This is designed to
provide direct bpf access in the caller process through
ConnectivityManager APIs.

The change also removes any statical link to
net-utils-device-common-struct from service-connectivity.
This is because net-utils-device-common-struct is already
included in framework-connectivity. Including it again in
service-connectivity would create a r8 build fail by circular
dependency.

Currently, data saver switch is controlled in NPMS, which
calls into NetworkManagementService and netd when switching
status. In netd, BandwidthController manipulates the
bw_data_saver chain to control the overall behavior.

However, this code are all platform implementation, which
are not updatable. In order to migrate data saver switch
from iptables to bpf, this API is needed for Connectivity to
change the implementation to directly write bpf in later
patches.

The TTL check and removal of expired services is currently only
performed when a mDNS query is sent. This can result in expired
services remaining in the cache if no queries are sent. To
address this, the remaining TTL will be checked when retrieving
services from the MdnsServiceCache. Add a new flag to enable
the expired services removal feature. This feature will be
implemented in subsequent changes.

This is useful going forward in particular because there will
be a default forbidden capability for LOCAL_NETWORKS. This
means it will be useful to be able to remove it.

It is also generally useful and we have been wanting to open
this API to the public, so this is a good opportunity to do so.

The kernel is actually not consistent in whether uids & gids
are signed or unsigned, and neither is our Java code, which
also commonly uses just 'int' for uid.  In practice values
greater or equal to 2**31 often don't quite work right.
For example icmp sockets are enabled via a sysctl that
takes a minimum and maximum gid - and these are signed int32s.

Surprisingly it appears no further fixups are required
