window.event is set on the wrong window when the target and the
callback are from different realms and the callback is an XPCOM
callback.

Most preference callbacks use literal strings for their domain filters, which
means that there's no need to make copies of them at all. Currently, however,
every preference observer node makes a separate heap-allocated copy of its
domain string.
This patch switches the domain string storage to nsCString instances, which
dramatically reduces the amount of unnecessary copies, at the expense of
making the callback nodes slightly larger.

There seem race conditions that we do a paint process when we started observing
the refresh driver but the first tick hasn't happened yet.

This call was added in bug 929362, but the key factor to fix the bug was just
setting a flag representing that the target frame doesn't allow the animation
running on the compositor and checking the flag in the function whether the
animation can be run on the compositor or not in later ticks. So the call
wasn't necessary in the first place.
The test case here fails without this fix. The test case actually doesn't
observe animation restyle count at all, so it might look a bit awkward in
file_restyles.html, if we add other test cases checking SchedulePaint calls
in future, we will move the tests in a different file.
(The reason there is no animation restyles in this case is that we properly
throttle the animation in this case.)

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.

Summary:
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.

We now provides more detailed information for audio (check sampling rate and channels if provided).
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.

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).
