Update content_decryption_module.h and other Widevine headers. This removes the
CDM8 interface and adds in the CDM10 and CDM11 interfaces. As such this patch
removes references to CDM8 from the code and adds some of the foundations for
supporting CDM10. Most of the CDM10 code will be implemented in another bug, but
there are a number of cases where it was straight forward to shuffle CDM8+9 code
-> CDM9+10, rather than deleting it and replacing it later.

We now only use the Chromium CDM interface, so there is no need to check isWidevine.
We don't use WidevineAdapter anymore so remove the related check and unused classes.

We have a minimum requirement of VS 2015 for Windows builds, which supports
the z length modifier for format specifiers. So we don't need SizePrintfMacros.h
any more, and can just use %zu and friends directly everywhere.

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.

The CDM process can't allocate shmems itself because it's sandboxed, so we
pre-allocate shmems in the content process and send them to the GMP process for
the CDM to use. Some sites seem to have encoded their content in such a way as
to cause the CDM to allocate and hang onto more frames than we pre-allocate; so
we run out of shmems in the GMP process, and the CDM can't allocate further
buffers to return output, and we fail.
So change the ChromiumCDMChild to allocate non-shmem-backed buffers if it runs
out of shmems, and return the result to the content process as an nsTArray.
Upon receiving that, the parent will send an extra shmem to the child, to
hopefully avoid the slow path again.
Also increase media.eme.chromium-api.video-shmems to 4, so that we're less
likely to hit this slow path in the wild. I've seen that Lightbox.co.nz and
Microsoft's EME test-drive require 4 shmems.

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.

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.

This works, at least on Windows, if the NSPR_LOG_FILE is set at a file
in the OS temp dir. This means we can turn on CDM logging in release
builds, in the sandboxed child process, without needing to recompile
to #define on logging.
This will make debugging issues with the CDM easier.
