* 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.
