e55a88d30f Use jarjar rule generator for connectivity rules
(This rolls forward part of a previous change, now that jarjar was fixed
to not get very slow when the number of rules increases).

Autogenerate connectivity jarjar rules at build time, to avoid issues
with forgotten jarjar rules or hard-to-diagnose errors introduced by
incorrect rules.

This change causes all classes in framework-connectivity(-t) and
service-connectivity to be jarjared into android.net.connectivity, but
still avoids jarjaring classes in com.android.server as before, to keep
it small.
For many classes this differs from the original jarjar rule.

Notes on implementation:

 - connectivity-jarjar-rules now has a subset
   framework-connectivity-jarjar-rules containing only the rules
   necessary for framework-connectivity. This is necessary because
   framework-connectivity cannot depend on rules generated based on
   service-connectivity, as there would be a dependency cycle
   (service-connectivity depends on framework-connectivity); Soong even
   crashes with a stack overflow.

 - framework-wifi.stubs.module_lib is added to
   framework-connectivity-pre-jarjar as it is necessary to build it (it
   is already in impl_only_libs in the defaults).
   It is unclear why framework-connectivity-pre-jarjar could build
   before that (possibly because it was only used as "lib" ?)

 - Fix package-private visibility; for example NattSocketKeepalive,
   TcpSocketKeepalive are not API so should be jarjared, but are used
   by ConnectivityManager which is not jarjared, so they are not in the
   same package after the change. Package-private members in the
   former 2 need to be public to be accessible. Changes in this commit
   are all that is needed, as demonstrated by followup commits that move
   the classes to a different package without further changes, and that
   enforce that no class in an API package gets jarjared.

 - framework-connectivity-internal-test-defaults is separated from
   framework-connectivity-test-defaults, for unit tests that need to
   access internal jarjared classes. Such tests need to use the jarjar
   rules themselves too, so this is only appropriate for connectivity
   internal unit tests.

This reverts commit 53eb35cd82.

Reason for revert: b/233081774, caused long build times in FrameworkNetTests

53eb35cd82 Autogenerate connectivity jarjar rules
Jarjar rules are hard to keep in sync with code, and hard to maintain
manually as the distinction between what should and should not be
jarjared is not always clear. This results in unsafe binaries that are
manually maintained, and developer frustration when something fails due
to incorrect jarjar rules.

Autogenerate jarjar rules at build time instead. This is achieved by
introducing a jarjar-rules-generator python-based library, which scans
pre-jarjar intermediate artifacts, and outputs jarjar rules for every
class to put it in a package specific to the module. The only exceptions
are:

 - Classes that are API (module-lib API is the largest API surface of
   the module)
 - Classes that have unsupportedappusage symbols
 - Classes that are excluded manually (for example, because they have
   hardcoded external references, like for
   ConnectivityServiceInitializer in SystemServer).

This change causes all classes in framework-connectivity(-t) and
service-connectivity to be jarjared into android.net.connectivity, but
still avoids jarjaring classes in com.android.server as before, to keep
it small.
For many classes this differs from the original jarjar rule.

b533550b06 QOS filter matching support based on remote address and port number for connected sockets
This CL adds APIs for telephony to perform filter matching based on
remote address if the socket is connected. Additional checks will be
performed on the state of socket to avoid the future callbacks in a
separate CL.

d059f21318 Remove usage of hidden InetSocketAddress constructor
The constructor is a hidden API, and used in a code path that can
never happen.
Replace it with a thrown exception (which should never be thrown either).

0942ad9f73 Use ParcelDescriptor.fromSocket instead of getFileDescriptor
Socket.getFileDescriptor$ is a hidden API. Instead, replace it with
ParcelDescriptor.fromSocket, which was created to handle such use-cases.

APIs. Add them to the connectivity boundary as they belong together with
ConnectivityManager.
