Use libjpeg-turbo instead of our own copy of libjpeg.

Check out libjpeg-turbo via DEPS.
Also checkout yasm via DEPS and copy some yasm build files from
Chromium.

- * For conditions of distribution and use, see the accompanying README file.
- *
- * This file provides a really simple implementation of the system-
- * dependent portion of the JPEG memory manager.  This implementation
- * assumes that no backing-store files are needed: all required space
- * can be obtained from malloc().
- * This is very portable in the sense that it'll compile on almost anything,
- * but you'd better have lots of main memory (or virtual memory) if you want
- * to process big images.
- * Note that the max_memory_to_use option is ignored by this implementation.
