bmeurer@chromium.org 90c8932596 Replace our homegrown ARRAY_SIZE() with Chrome's arraysize().
Our own ARRAY_SIZE() was pretty bad at error checking. If you use
arrasize() in a wrong way, the compiler will issue an error instead of
silently doing the wrong thing. The previous ARRAY_SIZE() macro is still
available as ARRAYSIZE_UNSAFE() similar to Chrome.
