X11.h #defines 'Status' and 'Failed' and 'Succeeded' which conflicts with
the enum in DetailedPromise. So rename the 'Status' enum in DetailedPromise
so that the build works on Linux.
Some of my changes here caused DetailedPromise to be included in more
places that it was before, which caused build failures on Linux.

This severs the ChromiumCDMVideoDecoder's connection with the CDM. The CDM process
will shutdown when the MediaKeys also severs its connection.

At this stage, I store video frames in memory in nsTArrays rather than in
shmems just so we can get this working. Once this is working, I'll follow up
with patches to switch to storing all large buffer traffic between the CDM and
other processes in shmems.
I'm not planning on preffing this new CDM path on until that's in place.

The MediaKeys accesses the ChromiumCDMProxy on the main thread. But the
ChromiumCDMVideoDecoder will need to access the ChromiumCDMProxy on the decode
task queue in order to get a reference to the ChromiumCDMParent so that it can
talk to the CDM (on the GMP thread).
Additionally we'll need to shutdown the ChromiumCDMProxy, and if we do that
on the main threrad while the ChromiumCDMVideoDecoder is trying to get the
ChromiumCDMParent reference, we could hit thread safety issues.
So we need to hold a lock while reading or writing from the ChromiumCDMProxy's
reference to the ChromiumCDMParent. So add a GetCDMParent() function to the
ChromiumCDMProxy which takes the lock while reading or writing the reference.
This means that the caller will always get a valid reference. There is no guarantee
that the ChromiumCDMParent isn't shutdown after the reference is taken; if that
happens, the ChromiumCDMParent returned will fail on all operations.
In a later patch in this series, the ChromiumCDMProxy will anull its reference
to the ChromiumCDMParent on shutdown, and cause GetCDMParent to return null.
So callers need to null check the return value of GetCDMParent.

This means the EME PDM implementation can safely tell when a CDMProxy is a
ChromiumCDMProxy, so we can create an appropriate MediaDataDecoder for it (in
the next patch).

This ensures that when we're using the ChromiumAdapter that we actually ask it
whether it'll work, rather than asking the adapter we're not using.

We currently use an adapter object to adapt plugins that don't conform to the
GMP interface to the GMP interface.
We use the WidevineAdapter to talk to the CDM from the two GMP IPDL protocols.
We will be using a single protocol to talk to the Chromium CDM, so we need a
new adapter which handles that.

We currently do two sync IPCs to launch a GMP; one from content to main process
to get the nodeId and a second to get a GMPContentParent for that nodeId.
We use the nodeIds to ensure that the GMPVideoDecoder and GMPDecryptor actors
correspond to the same CDM instance/process. However once we switch to having
one protocol that encompasses both decryption and decoding, we don't need to
worry about making sure our decoder and decryptor actors match up, as we only
have one underlying connection to the CDM instance.
So we can merge the get nodeId and get GMPContentParent operations into a
single operation that does both. To do this, we just need to pass the
parameters used to calculate the nodeId in the LaunchGMP message.
Once we've switched EME over to using the CDM via a single actor, we can remove
the nodeId nsCString from our media code and from GMPVideoDecoder and
GMPVideoEncoder.

Under some circumstances, and seen on Windows 8, a decoded sample can be returned without the MFT returning MF_E_TRANSFORM_STREAM_CHANGE.
For historical reasons, we required that message to be returned at least once to set the output image size. This was required as the decoder used to be recycled with different video streams.
This is no longer the case, we can rely on the video info instead. It also greatly simplifies the code
