Generating hidden API lists has grown in complexity and the original
Makefile rule has become a bottleneck for build times. Rewrite the
logic in Python.

* changes:
  Fix DHCP options sent by DHCP server
  Fix BOOTP fields for server-generated DHCP packets

This reverts commit 3284e350.

Reason for revert: breaks most branches

Bug: 112867975
Change-Id: Icb27e193529f523f4cf07ef55e19625c402a2d3b

Add Android metered option, rebinding time option (T2), and match
current order of options.  Current DHCP server uses subnet_mask,
broadcast_address, router, name_server in this order.

Test: DhcpServerTest.py:test_discover_paramrequestlist passes
      atest FrameworksNetTests passes

Set siaddr to the server address instead of zero in DHCPOFFER
Set siaddr to zero instead of the server address in DHCPNAK
Set giaddr to the relay address instead of the server address in
DHCPNAK
Set giaddr to the relay address instead of zero on DHCPACK and
DHCPOFFER
Set server identifier option in DHCPNAK

Current code is not compliant with RFC2131 and does not match dnsmasq
behavior. It was not an issue until now since the packets were only used
by the DHCP client, which does not send DHCPOFFER or DHCPNAK.

Bug: b/109584964
Test: following DhcpServerTest.py regression tests pass:
      test_discover_bootpfields
      test_request_selecting_inuse
      test_request_rebinding_relayed
      test_discover_relayed_broadcastbit
      test_request_rebinding_wrongaddr_relayed
      Also: atest FrameworksNetTests

* changes:
  Migrated various apps under frameworks/base/packages/Shell  to androidx
  Migrated SystemUI & SettingsLib to androidx

From current code, it will check if the device connected before
getConnectionState. We can remove this check logic because
HidHostService will do it.

* connect: remove debug log of connect connected device. HeadsetService
  will check it and print related log.
* disconnect: remove connected device check logic. HeadsetService will
  check it.
* getConnectionStatus: remove connected device check logic.
  HeadsetService will check it.
* wrap if/else statement in curly brackets.

Test: as follows
    - built, flashed, booted
    - runtest frameworks-net passes
    - manual bluetooth tethering testing doesn't seem to trigger any
      actual tethering, since bt-pan interface keeps going down on
      test device (IpClient never really starts up fully)

The newer implementation is disabled by default with this CL. Ultimately
the intention is to enable it by default.

Bug: b/109584964
Test: set tether_enable_legacy_dhcp_server to 0, ran DhcpServerTest.py,
      observed new behavior. Added tests in CL also pass.

Some fields in WifiInfo are not written into Parcel so
these fields will not be carried over process boundaries.
