WebKit style guide (https://www.webkit.org/coding/coding-style.html) explicitly states: > All implementation files must #include "config.h" first. > Header files should never include "config.h". Also, it isn't currently being used. TBR=reed@google.com This just removes unused bits. Review URL: https://codereview.chromium.org/1256133004
