Reason for revert:
Breaking Android framework build, which still uses AvoidXfermode. (failure shown here: 565b76b4bd/logs/build_error.log)
Here is the Java class that uses it: https://cs.corp.google.com/#android/frameworks/base/graphics/java/android/graphics/AvoidXfermode.java&sq=package:android
It has been deprecated. The glue code (which actually references the Skia file) is here: https://cs.corp.google.com/#android/frameworks/base/core/jni/android/graphics/Xfermode.cpp&q=Xfermode.cpp&sq=package:android
Mike suggested we move the implementation into Android, which is fine with me.
