[Bug 26776] Diagnosing and resolving CDM errors needs a numeric systemCode (deleted with MediaKeyError)

https://www.w3.org/Bugs/Public/show_bug.cgi?id=26776

--- Comment #25 from David Dorwin <ddorwin@google.com> ---
Jerry has an action to provide more information about the use cases he is
targeting with this event and which object it should be fired at.

Comments in the meantime:
* It's unclear if the latest proposal solves the logging use case.
 * Many of the use cases for system code logging are related to keystatuses,
which already has a separate event.
 * Others result in rejected promises.
  - Note: Chrome is currently appending the system code to the DOMException's
message.
* Some of the use cases may be covered by and/or better discussed in bug 27067.
* There are reasons to avoid an event (see comment 20). While a string provides
some level of disincentive to make application decisions, it is still possible
and less useful than a numeric value.

I believe we agreed not to subclass Error. Among other things, we might need to
define our own script bindings.
