In addition to updating the interface, this patch also significantly alters the
structure of this test. In particular, it removes the Test* functions in favour
of using template magic.
I did this because I noticed that, in the majority of cases, the stub function
was being called with all zero arguments, and then we check for the expected
error code. I thought that maybe we could replace that repetition with some
templates that instantiate a blank tuple that may then be applied to a callable
object.
See the (MAYBE_)TEST_HOOK* and TEST_DETOUR* macro definitions for detailed
information about how to use these things.
The test successfully completes with both 32-bit and 64-bit builds.

This patch makes the interceptor's AddHook functions private, and converts
the stubs from simple function pointers into objects containing both the stub
function pointer, plus a INIT_ONCE sentinel.
Setting a hook now requires calling Set or SetDetour on the stub, which ensures
that the hook attempt happens once and only once.
The constructor for the new object is constexpr, so it should not generate
static initializers if it is declared statically.
Note that, as a corollary of the new behaviour, we no longer need to set guards
around any hook setting code. I have removed those when present.

This commit implements the CONTENT_FRAME_TIME metric for the webrender code
path. It follows the same structure as the previous commit implementing it for
the non-webrender code path.

This commit adds the CONTENT_FRAME_TIME metric which tracks the time from the beginning
of a paint in the content process until it is presented in the compositor.
There is existing logging for frame latency which tracks from the beginning of a refresh
tick until the frame is presented. This is undesirable for this probe as javascript and
layout can run in this time period. So this probe uses the existing infrastructure for
logging frame latency, but uses a start time from BeginTransaction in layer manager.

clang-cl complains about things like:
z:/build/build/src/obj-firefox/dist/include/mozilla/interceptor/VMSharingPolicies.h(53,50): warning: use of identifier 'GetLocalView' found via unqualified lookup into dependent bases of class templates is a Microsoft extension [-Wmicrosoft-template]
return TrampolineCollection<MMPolicy>(*this, GetLocalView(), GetRemoteView(),
^
in various files in interceptor/, and since the warnings are in headers,
rather than in sources, they're rather annoying. Let's fix this to be
standards-complaint and make clang-cl stop complaining.
Summary:
There are two tests failing:
Test that decodingInfo rejects if the video configuration contentType has more than one parameter
and
Test that decodingInfo rejects if the audio configuration contentType has more than one parameter
Our nsContentTypeParser doesn't provide an ability to count the number of parameters, only to retrieve one if the name is known.
Considering the scope of the extra work, we'll leave it as-is for now

Summary:
Additionally, consider all videos <= 480p to be smooth and power efficient as:
1- Hardware decoding it typically not used for those
2- We can't do any better
3- Any machines should be able to do 480p

Summary:
The Apple VT decoder requires SPS+PPS at construction time. If not provided, in earlier macOS it used to give an error. In the current 10.13 it appears to work, however the decoder always report to be software only.
To properly determine the decoder capabilities, we construct a SPS NAL from the codec mimetype provided.
Details on the structure of the mimetype can be found in https://tools.ietf.org/html/rfc6381#section-3.3 and is a 1:1 match with the data found in the SPS.

We'll need it to properly build a SPS/PPS extradata later. Also, change the types used. The original data is stored on two bytes ASCII, it will always fit in a uint8_t. Additionally, this is how those values are stored in a SPS.

Bug #: 1409664
Differential Revision: https://phabricator.services.mozilla.com/D1718
Summary:
By default, when creating a H264 decoder it is wrapped into a H264Converter which will only create the actual decoder once a valid SPS/PPS has been seen.
As creating valid SPS/PPS NALs isn't trivial, when all we care about are capabilities of such decoder, we do not wrap the decoder so that it will be immediately created.
We can then test its capabilities.
We only enable this on windows, as on mac we need to generate a SPS/PPS, otherwise the mac decoder always report that HW decoding is not enabled.

And check for the power efficient attribute. We directly correlate this information with the decoder being hardware accelerated or not. All audio codecs are deemed to be power efficient.

Differential Revision: https://phabricator.services.mozilla.com/D1627
Summary:
We can't create a H264 VT decoder until we have all SPS/PPS NALs, which makes it tricky to generate when we only want to check if H264 is supported.
On mac, we can reasonable assume that hardware acceleration is always supported (though on a mac pro 2013 that isn't the case or hackintosh with nvidia cards).
