This reverts commit 3f87250a4f0e6c69002fbcdfb995b0dfcd7bf710. Reason for revert: Downstream is fixed Original change's description: > Revert "Remove RTC_DISALLOW_COPY_AND_ASSIGN usages completely" > > This reverts commit 5f0eb93d2a44cec2102fc8c3757d5bb814bd145f. > > Reason for revert: Breaks downstream project.
