Replace the MacSandboxType_Plugin sandbox type with MacSandboxType_Flash and MacSandboxType_GMP so that there is a 1:1 association between MacSandboxType values and sandbox policies.
Remove the MacSandboxPluginType enum. Instead of having different MacSandboxPluginTypes, we will just have MacSandboxType_GMP. We only use GMP for two plugin types, Widevine and OpenH264, and they only differ in that Widevine requires accss to the WindowServer.
Remove the MacSandboxPluginInfo struct and move the two needed fields pluginPath and pluginBinaryPath to MacSandboxInfo.

This builds on earlier patches to move all remaining resource requests
to occur during the visibility pass, and change the block on glyph
rasterization to occur after the visibility pass.
This allows batch generation to occur during the prepare_prims pass,
which is useful for generating a batch set per-dirty-region, while
only doing a single pass of the picture / primitive tree.

This patch changes glyph requests in the resource cache to occur
as soon as a text run is found to be visible, rather than during
the prepare_prims pass.
This has two major benefits:
- (with other patches) will allow some batching code to run
during the prepare_prims pass.
- allows glyph raster worker threads to start earlier in the
frame, which may lead to less time blocking on the workers.

This is a first step towards allowing (some) batching work to be
done during prepare_prims pass rather than render pass building.
This is prep work related to output different batch lists for a given
picture (e.g. a different batch list per dirty region), rather than
replaying the same batch list.

This early return is just an optimization to prevent the DAG from becoming too complex, and if we're keeping the list linked, then we know it won't be getting more complex on the current paint.
Future paints that actually modify the list will still take this path.

In trying to diagnose bug 1538540, I'm hitting my limits as far as
simply staring at the code and trying to work out possible ways to
hit the crash goes. This assertion will split the search space into

The comment in nsDisplayTransform::GetTransformForRendering() clearly
says that |aOutOrigin| should return the same offset as GetTransform().
GetTransform() will pass the offset to GetResultingTransformMatrix()
which will round it in many cases to avoid subpixel blurry rendering.
But GetTransformForRendering() doesn't take this rounding into account,
thus contradicting the intent described by the comment.
This rounding is important to keep subpixel behavior consistent with
or without webrender enabled. Currently, SVG will be rendered blurry
in some cases if it's at a subpixel position. After fixing the problem
in non-webrender case, the strange blur still occurs in webrender case.
It turns out to be caused by this inconsistency.

We should snap subpixel value at nsDisplayTransform::GetResultingTransformMatrix
for outer svg and the anon child. This will solve blurry rendering for subpixel position
when webrender is __not__ enabled.

We're allowed to take some liberties as to what the default value and behaviour
we assume for the 'preload' attribute on HTMLMediaElement by the spec. On
desktop we assumed preload="metadata", while on mobile we assumed the default
of preload="none" to save data. On mobile we also assumed that preload="auto"
meant preload="metadata".
I think it makes sense to instead of always assuming that data on Android is
always expensive, we can instead detect if we're running on a cellular connection,
and preload frugally then, otherwise aggressively.

Normally when downloading media data we throttle the download only if we're
ahead of the read cursor more than the "readahead limit", and if we estimate
that the connection is fast enough that we'll be able to download at a rate
fast enough to playback in real time if we resume it later.
On mobile we additionally override this so that we always throttle the download
once we're ahead of the read cursor by the readahead limit. This is to save
data. I think we can relax this to only do this override if we're on a
cellular connection; if we're on WiFi we can assume data is cheap.

In GeckoView the nsINetworkLinkService doesn't work in the content process, as
we don't seem to have an AndroidBridge there, so just maintain the network
connection type on the ContentChild.
(I had considered keeping this on the NeckoChild, but the creation of that is
initiated from the content process side, and there's not an easy and clean way
to have the parent process send us the connection type after construction of
the NeckoParent, other than have the NeckoChild request it either
synchronously, or doing it async and hoping it's not asked for the value before
the response comes in.)
