This enables us to identify GMPDecryptor instances in the child process, so that in a later patch when we create a GMPVideoDecoder instance, we can associate it with a GMPDecryptor. Then the cdm::ContentDecryptionModule8 instance that these two actors are adapted to can know whom it's supposed to respond to. We use the IPDL PGMPDecryptorChild actor ID as the GMPDecryptor's ID. This is unique per GMP process, which is sufficient. MozReview-Commit-ID: 7NKND9VjPUW --HG-- extra : rebase_source : da14d9a8a7313a609e30649af1a23e79b3e401fe
