[Cocoa] AVContentKeyRequest is recreated when renewing via
-renewExpiringResponseDataForContentKeyRequest:
https://bugs.webkit.org/show_bug.cgi?id=266282
rdar://119555484
Reviewed by Andy Estes.
In certain configurations of AVContentKeySession, when a request is renewed via
-renewExpiringResponseDataForContentKeyRequest:, instead of returning the same
AVContentKeyRequest object in the
-contentKeySession:didProvideRenewingContentKeyRequest:
delegate callback, it will return an entirely new AVContentKeyRequest. This
breaks
WebKit's renewal path.
To work around this behavior, track the request being renewed in a new ivar,
and when
the delegate method is called, use both requests' -identifier property to check
equality. Then replace the old request in the list of m_requests with the new
request.
