The log priorities and ids are in an NDK header, available to everyone. Move CHECK into its own header for now. This would be better if it was more like the <android-base/logging.h> CHECK family, but I don't have an easy way to do that without lots of copy & paste, so punting for now. Bug: https://issuetracker.google.com/issues/119713191 Test: boots Change-Id: I4566be8a0a024fede0e2d257c98b908ec67af2a8
