This has the unfortunate side effect of importing all of these names into the
chrome:: namespace.  previously, they were scoped to NotificationType.  it seems
like we should probably employ a naming convention to help.

  chrome::NOTIFICATION_BROWSER_OPENED
  chrome::NOTIFICATION_BROWSER_WINDOW_READY

Then, I would do similar treatment for the ones defined in content/.  For
example, NotificationType::ALL becomes content::NOTIFICATION_ALL.

Another option might be to define a NotificationType struct in both chrome:: and
content:: namespaces, so we'd end up with
chrome::NotificationType::BROWSER_OPENED and content::NotificationType::ALL. 
However, that leaves a bad taste ;-)  It seems like too much.

I apologize as this is probably a fair bit of busy work to implement!

What about a second namespace around the anonymous enum, e.g.

namespace chrome {
namespace notify {

enum {
  ...
}

}
}

Would that be just as good, and perhaps easier to implement?  You'd get e.g.
chrome::notify::BROWSER_OPENED etc.

Done.

By the time I read this I had already done the donkey work to rename all
notifications to NOTIFICATION_ :)
