This will eventually replace GMPCDMProxy. Methods will be implemented in later
patches.

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.

The clock that GMP currently exposes to CDMs has second precision. Whereas the
clock that Chromium exposes to CDMs has microsecond precision. We should use
the same clock as Chromium does (since we have its code in our tree already) so
that our CDM harness is as compatible to Chromium as possible.

This menas we can have GMPVideoDecoder's AVCC -> AnnexB conversion done by the H264Converter, and
simplify the code in WidevineVideoDecoder.

The work I did in bug 1306314 seems to have either regressed or never worked
properly for multiple CDM same origin processes. I'd guess the decryptor IPDL
protocol actor ID must not be as unique as I thought. So if we just use a
counter managed by the GMPDecrytorChild, we'll get a per CDM unique ID, which
is sufficient.

This makes it easier to reuse in the ChromiumCDM code.
Also add an ExtractBuffer() method, which allows us to Move() the contained nsTArray
out without needing to copy the data.

The job id is just a counter, so rather than have other users of DecryptJob
reimplement their own counter, we can push the id/counter code into DecryptJob
itself.
