Previously the calculation of the expected ADD_TIME implicitly depended
on the default timezone of the test device and thus might have
different values and cause test failures. This fix updates the test to
always use "GMT" to generate the ADD_TIME

  [XFRM_MSG_NEWSA] Support xfrm_selector and xfrm_id

In PrivateDnsConfig class, `useTls` is replaced with `mode`.

Debugging the SIGABRT of this function is annoying because the module
can be built from source or pre-built. It requires finding the correct
version of the symbol to get the correct line number. In addition, there
are 7 consecutive aborts in source code, it is hard to tell whether the
symbolized call stack shows the right line number or not. Adds error
trace before abort so we can identify the root cause without even
symbolizing the call stack of SIGABRT.

The code currently calls RandomInt twice to generate an address.
For example, if you want to generate the address 192.168.A.B,
RandomInt will be called twice to generate the values for A and B.
To save resources, we can avoid calling RandomInt twice by reusing
the same random value with different masks for A and B.
Before:
  -  RandomInt() & 0xff00 -> A
  -  RandomInt() & 0x00ff -> B
After:
  -  RandomInt() & 0xffff -> A.B

On mobile networks it is more likely that the user needs to top up or
get a mobile data subscription, rather than "sign in" as the previous
messaging was suggesting.
Following feedback from interaction designers / UX writers, change the
strings to be more appropriate for the most common use-case.

      manual test on mobile network force-detecting a portal.
Change-Id: I5b4d4a17fd507d8cf3c9863cf23b5fedb258852e

The issue arises when the network becomes validated based on the
isCaptivePortal success with HTTPS, even though the HTTP probe
hasn't been executed yet. Given that there is no way to ensure
HTTP probe was sent in this case, the pass condition should be
relaxed, allowing a single https query instead of expecting both.

framework-connectivity-flagged-apis-droidstubs is used by
jarjar-rules-generator to avoid jarjaring flagged apis.
But, this usage of --show-annotation FlaggedApi in the flag is not
supported.
So this CL removes --show-annotation FlaggedApi.
As far as framework-connectivity-flagged-apis-droidstubs contains
flagged APIs, it's fine that this droidstubs also contains non-flagged
APIs.

This patch changes the implementation of UnicastResponder in the
RouterAdvertisementDaemon with FdEventsReader. The change includes
replacing Thread with HandlerThread, create socket in non-blocking
mode (required by FdEventsReader) and use FdEventsReader to listen
to the solicited RS packets. Two commands (CMD_START & CMD_STOP)
were added to control the lifecycle of the FdEventsReader.
