This is a reland of https://codereview.webrtc.org/1903553003/ but with the SRTP changes removed, since they're needed downstream. The defines that can be used to alter the include paths for Expat and gtest are no longer needed in WebRTC or Chromium. Remove them to simplify GYP. Removed defines: EXPAT_RELATIVE_PATH GTEST_RELATIVE_PATH They're all set in the Chromium build so this shouldn't affect Chromium: https://code.google.com/p/chromium/codesearch#chromium/src/third_party/libjingle/libjingle.gyp BUG=webrtc:4256 NOTRY=True NOPRESUBMIT=True TBR=perkj@webrtc.org Review-Url: https://codereview.webrtc.org/1925733002 Cr-Commit-Position: refs/heads/master@{#12536}
