To allow GMPs time to update to new GMPDecryptor versions, we support the latest GMPDecryptor version, and the previous. In order to support a consistent interface to Gecko, we adapt the previous GMPDecryptor version to the latest in the GMP child process. So Gecko always thinks it's talking to the latest version. We also make gmp-fake deliberately support the previous GMPDecryptor version, to ensure this code path remains tested.
