    Start count of potential configuration to 1

    - call is paused when receiving a response with all streams having RTP port set to 0
    - add support for 100rel support/require level

    Test scenario where connection and origin IP are not identical

Repair streaming from file feature of AudioStream/VideoStream. Fix issues with VP8 processing of timestamp through encoder and decoder, and fix a case where an incomplete frame was not marked as invalid as it should have been.

Because Pushkit and Invite not recived in the same time, so we can create duplicated call for the same callid. Use call_logs to end this duplicated call which already ended.

- Count unread chat messages in all Chat Rooms with a weak address testing.
- Update Readme to use docker image with cmake 3.0 for Android build

Fix H265 random decoding errors when the H265 stream is generated from an Android device. It seems that the removal of start code emulation prevention bytes is not required for MediaCodec, and moreover if done, it creates random decoding errors at the other end (even if the other end is not a MediaCodec implementation).

Audio : avoid returning audio card if null is set. Fix getting capture card on setting input and not playback. Allow setting NULL device (case of no cards available). Fix tests to not take account of system audio cards (maybe need to be done directly on core creation) Fix UWP tester in case of xml wasn't needed.
* Stop audio stream when setting new device and Filter don't implement MS_AUDIO_CAPTURE_SET_INTERNAL_ID and MS_AUDIO_PLAYBACK_SET_INTERNAL_ID. This fix allow changing device on Desktop while ringback.
* Add Audio stream stop count for tests.
* Change audio_stream_set_<input/output>_ms_snd_card prototype to know if MS_AUDIO_CAPTURE_SET_INTERNAL_ID/MS_AUDIO_PLAYBACK_SET_INTERNAL_ID have been called in filters.
* Add debug feedback when setting card.

Install docs only if requested (This is a workaround to having a path with too many characters on Windows where it is not needed to have docs).
Export 2 liblinphone_tester functions to allow UWP to use them for fixing dns resolver. Fix dns resolver on UWP tester that didn't point to the right IP.
Wasapi : Add default card only if it exists.
