Hmm...Wonder if this is necessary.  We're using C++ style comments in this file,
so is it ever compiled as string C?

[mef, 2014/03/03 19:15:13]

Done.

[mef, 2014/03/06 23:14:25]

It turns out that JNI relies on its own name mangling, which is not compatible
with C++ name mangling. We should be able to remove this once we switch to
generated JNI headers.

Should use C++ style comments in C++, since that's what chrome normally uses.

[mef, 2014/03/03 19:15:13]

Done.

Use enum or const.

Think for most of these, you can move the function name up a line.  I'm assuming
the funky names are necessary.

[mef, 2014/03/03 19:15:13]

I think we could and should replace these with generated jni headers. I'll look
into that.
