BTW, what does "CONTENT_EXPORT" prefix (macros?) do? Some of the constants are
prefixed with that and some not; I failed to find an obvious reason. So I'm
unsure whether this new constant needs it.

One of the configurations we build Chrome in is a shared library build. On
Windows, that means multiple DLLs (chrome, content, etc.). Now, DLLs need to
declare the symbols they're exporting, otherwise you can't link against them. At
the same time, if you want to use a symbol from a different library, you need to
import it. The FOO_EXPORT macros let you do that, depending on whether you
include a file from inside or outside of the FOO DLL. What this means
effectively is that if you want to reference the flag outside of content/ (which
we do want in this case), we need to add the macro.
