On Linux some implementations of time(0) appear to be suffering from integer
overflow and giving us the wrong dates. This causes the time we expose to the
CDM to be wrong, and so licenses passed to the CDM are failing to authenticate,
and Netflix is thus broken on some Linux systems.
This is only happening in Firefox 54 and earlier, as in those versions we use
the WidevineDecryptor to talk to the CDM. In 55 (in beta) and later we use the
PChromiumCDM protocol to talk to the CDM. This doesn't use time(0) to get a
time for the CDM, so it's immune to the problem here.
So this patch makes the GetCurrentWallTime() implementation in
WidevineDecryptor match the code currently being used on Nightly and Beta in
the ChromiumCDMChild::GetCurrentWallTime() function.
Since we use the PChromiumCDM protocol to talk to the CDM on Nightly and Beta
by default, the WidevineDecryptor isn't actually being used on Nightly and
Beta. So this patch will only cause a behaviour change in Release, which still
uses the old backend. However it will make Release run the same code that we're
running in Nightly and Beta, so it should be safe to uplift to Release.

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.

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.

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.

The OnSessionClosed() callback is happening on a timer, after
WidevineDecryptor::DecryptingComplete() has been called. So mCallback could
actually be non-null because DecryptingComplete() has been called, but the
object pointed to by mCallback has been deallocated, and mCallback is a
dangling pointer.

Now that GMPParent detects whether gmp-clearkey can decode using AAC/H.264
using WMF before reporting gmp-clearkey's GMPParent can decode AAC/H.264, we
don't need the GMPDecryptorCallback::SetCapabilities() callback from the GMP to
signal to the PDMFactory that the GMP can decode. We can now trust what the
GMPService tells us.
So we can remove the "waiting for CDM caps" step in the state machine's startup
sequence. And all the plumbing. :)
If we need more caps, like for an decode-and-render path, we can declare those
as API strings in the info file.

We've observed some crashes derefing the callback pointer, which may be
occuring due to shutdown happening before init has setup the callback pointer.

Add a GMPAdapter implementation that adapts the Widevine Chrome CDM to
the GeckoMediaPlugin API. We're still allocating memory for video frames
in non shmem buffers, and copying them over to a shmem before returning
them to Gecko, we can fix that at a later date. I hook this adapter up
in a later patch in the series.
