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.

This change ensures that we don't create a new random node Id for every
MediaKeys object using Widevine - which has the effect of ensuring
Widevine CDMs that are same origin get created in the same process, and
that persistent storage can be used and retrieved.

Store a mapping of decryptor ID to the CDM instance that the corresponding
WidevineDecryptor is using. This allows us to link GMPDecryptor instances
with the corresponding GMPVideoDecoder.
The CDM is stored inside the CDMWrapper, so that we destroy the CDM instance
when the last reference to the CDM is dropped.

We only have one version of a GMP installed at once anyway. This version code
is to support Adobe Primetime, and that's disabled.
Making the behaviour of this code simpler will make it easier to have the
same behaviour of the GetGMPVersion code in e10s and non-e10s mode.
I will be removing this code soon, but I will do that in a later patch, so as
to not complicate the uplift.

In order to avoid doing a synchronous call from content process to chrome
process in order to determine what GMPs are usable, maintain a cache of GMP
capabilities in the content processes.
We must seed the cache when content processes are created, as the GMP service
is started up and GMPs are added to it before the first (or any subsequent)
content process is created.

This patch makes most Run() declarations in subclasses of nsIRunnable have the
same form: |NS_IMETHOD Run() override|.
As a result of these changes, I had to add |override| to a couple of other
functions to satisfy clang's -Winconsistent-missing-override warning.

Update handling of VP8, VP9 to enable decryption and decoding via widevine.
Update handling with further validation to make sure that invalid video types
are rejected when trying to create widevine decryptor session or init widevine
decoders.

It was possible for WidevineVideoDeocder when allocating shmems for frames to
become reentrant. If a further frame was allocated during this reentrancy it
would be returned before the first frame being allocated. As frames are fed into
the decoder in order, altering this order for returned frames would result in an
out of order display.
This is addressed by keeping a deque of frames and allocating them in order.
There are changes to guard again reentracy issues with draining also. Previously
it was possible to drain a decoder, but still have a frame allocation be
pending, resulting in a drain being completed, and a frame being returned follow
that. This has been addressed by not draining during reentrancy.

We're already routing the "gmp-changed" observer service notification over from
the chrome process to the content process, and it fires at pretty much the same
time as the "gmp-path-added" notification (and a few more) so we can just switch
to have the MediaKeySystemAccessManager listen on that notification instead, and
we'll be e10s compatible.

The Adobe GMP only supports up to GMPDecryptor version 7. We're now up to
version 9. So we need to provide an adaptor to convert the old version to run
with the new interface.
