Reviewed by Andy Estes.
When adding a workaround for a platform change in behavior in the modern
AVContentKeySession path,
a behavior was introduced which narrowly affects the way Netflix.com preloads
keys. Previously,
a "renew" message would result in the resulting AVContentKeyRequest replacing
the entire set of
pre-loaded keys from the previous request, some of which were in use by Netflix.
Rather than replace the entire set, replace only the AVContentKeyRequest within
the batch of requests
whose contentKeySpecifier has a maching identifier to the replacement.
