In case some legacy third-party things were relying on those files being
under a unix/ directory, revert the part of changeset c94e87a18096 that
renamed global-platform/unix to global-platform/gtk.

As per Bug 1355252, the EME spec requires our
navigator.requestMediaKeySystemAccess() function to reject request for
configurations which don't contain at least one MediaKeySystemCapabilities
(audioCapabilities or videoCapabilities).
That's step 15 of this algorithm:
https://w3c.github.io/encrypted-media/#get-supported-configuration-and-consent
We also shouldn't be assuming that WebM and MP4 normatively imply a specific
set of codecs and codec constraints, as that violates step 10 of the "Get
Supported Capabilities for Audio/Video Type" algorithm.
https://w3c.github.io/encrypted-media/#get-supported-capabilities-for-audio-video-type
Making this change has the effect of causing us to reject configurations with
MediaKeySystemCapabilities where those capabilities don't specify a codec
string.
This patch adds a deprecation warning to encourage authors to make their sites
spec compliant.

The "platform" chrome flag requires an irrelevant "content" chrome
manifest entry, while it's only used for locales. It only has exactly
one use, which can actually be replaced by uses of the "os" flag.
Note, we're doing something similar with the "os" flag for skins in
e.g. browser/extensions/pocket/jar.mn.
Unfortunately, for determinism reasons, the chrome manifest entries from
jar.mn are sorted (per bug 982075), so keeping global-platform/unix
would leave it appearing after /mac, and would override it on mac
because of the lack of "os" flag on the /unix entry (we can't put "os"
flags on that entry because we can't do something like os!=Darwin &&
os!=WINNT). So we move it to /gtk such that it always comes before /mac.

Preliminary telemetry indicated 15% of users of EME are in an insecure
context. We'd better log a warning to the web console to inform authors
that their sites will stop working, rather than just breaking them!

Other browsers do not support any of these (IIRC), telemetry reports
essentially zero usage, and supporting them is contrary to the DOM spec.
Notes on specific events:
CommandEvent and SimpleGestureEvent: These are not supposed to be
web-exposed APIs, so I hid the interfaces from web content too
(necessary to avoid test_all_synthetic_events.html failures).
DataContainerEvent: This was a non-standard substitute for CustomEvent
that seemed to have only one user, so I removed it entirely and switched
the user (MozillaFileLogger.js) to CustomEvent.
ScrollAreaEvent: This is entirely non-standard, but we apparently expose
it deliberately to web content, so I didn't see any reason to remove it
from createEvent.
SimpleGestureEvent and XULCommandEvent: Can still be created from
createEvent(), but not by content.
TimeEvent: This is still in because it has no constructor, so there's no
other way to create it. Ideally we'd update the SMIL spec to add a
constructor. I did remove TimeEvents.

Even for very small layers we want to avoid doing work on the main
thread.
At the same time, however, increase the minimum active layer size for
animations which come from restyles. These involve the main thread
anyway, so there is less to be gained from using an active
layer. Since switching items between active and inactive can have
large knock-on effects, we want to make sure it really is worth making
the layer active.

This patch adds a new performance warning type for the case when we start
a transform animation at the same time as an animation that includes a
geometric property. In that case we run the transform animation on the main
thread so that it is synchronized with the geometric animation (which we can
only run on the main thread).
This differs from CompositorAnimationWarningTransformWithGeometricProperties
in that this applies across different elements whilst the existing warning
only covers the case when the same animation animates both transform and
geometric properties.
