Merge master into merge-0.14-into-master
Conflicts:
- gRPC.podspec
- Only had non-trivial changes in the core file list, which will need to be
regenerated (in gRPC-Core.podspec).
- src/objective-c/BoringSSL.podspec
- Had trivial conflicts in the version.
- src/objective-c/examples/RemoteTestClient/RemoteTest.podspec
- Trivial conflicts in quoting.
- src/objective-c/examples/Sample/Sample.xcodeproj/project.pbxproj and
src/objective-c/examples/SwiftSample/SwiftSample.xcodeproj/project.pbxproj
- The master version is used, pending testing. The 0.14 version had emoji and
some unneeded entries.
- src/objective-c/tests/Podfile
- Added CronetFramework pod, and warning silencing from master.
- templates/gRPC.podspec.template
- Deleted.
- third_party/protobuf
- Using master commit, but need to verify if it works for frameworks.
