Upstream commit: https://webrtc.googlesource.com/src/+/989dfe373094bc609a2784027cc995f3be4db184 Improve testing in stun_port_unittest Before this cl, the test only used local addresses (i.e. no NAT) and therefor could not really distinguish between a server reflexive address and a host address. Consequently, there were multiple errors in the test that compared against "wrong ip", (which happened to pass since there was really onyy 1 ip used). I noticed the totally bogus testing when adding a feature to StunPort. BONUS: Create a binary rtc_p2p_unittest that run only the p2p/ unittests :) BUG=b/378415408 Change-Id: I19fb0b556efca1053a23eccc3129670395a95d48 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/378823 Commit-Queue: Mirko Bonadei <mbonadei@webrtc.org> Auto-Submit: Jonas Oreland <jonaso@webrtc.org> Reviewed-by: Mirko Bonadei <mbonadei@webrtc.org> Cr-Commit-Position: refs/heads/main@{#43987} Differential Revision: https://phabricator.services.mozilla.com/D243993
