* Suppressed various compilation warnings
* Fixed CodeQL warning
* Fixed build warning on Android and Linux
* Fix build warning on Visual Studio
* Update target Android SDK version to 29 (for pjsua2 & app), to avoid gradle error: 'Google Play requires that apps target API level 29 or higher'.
* Add support for Camera2 API to ipjsua android app.
* Fix assertion on Win32 app (MSVC2005) because ICE transport info size is 160 bytes while the allocated buffer is just 144 bytes.
* Enable python unit test on windows for github actions.
* Avoid assertion in pjsua test caused by double calling of pjsua_conf_remove_port()
* pjsua-test:
- Update pjsua-test module call: wait ICE update before checking media
- Attempt to fix all failed tests by sipp module: changed SIPp port from 6000 to 50070 (port used by recvfrom module)
- Update call module: confirm codec priority after change, fix DTLS-SRTP expect may race with state CONFIRMED
- Add timeout check in telnet-ing to pjsua
- ICE nego may race with call state CONFIRMED, so mod call better just sleep instead of expecting 'ICE nego success'.
* Other unit tests:
- Print stack trace on crash on Linux and DarwinOS via SIGSEGV signal handler.
- Update resolver test: print log on callback error, replace assertion checks with error return, fix comments, sleep periods, fix received packet count may be > 1 if server ignore the request (for example when the test machine experiencing high CPU load).
- Update ccpp.yml: add -g for jobs with unit-tests.
- More lenient on tsx retransmission count check in pjsip-test.
- Update tsx_uac/s_test.c: allow retransmission timing diff from 150 to 500ms to accommodate possible CPU spike on some test machines.
