Rename GeckoArc macro so it sounds like it's useful for already-threadsafely-refcounted objects.
<!-- Please describe your changes on the following line: -->
This is just some renaming. I will want to use this macro with some objects that support thread-safe refcounting, and which thus don't use `nsMainThreadPtrHolder`. For fun I pushed a stylo try run with this change: https://treeherder.mozilla.org/#/jobs?repo=try&revision=4b6d906b423e

This adds support for more background-repeat modes using the legacy
rasterization backend.

stylo: support background-size and corner gradients
Forgot to fix this in the midst of all other things fixed in #12945
<s>(not yet tested, need to figure out how to test bg-size with gradients)</s>

Expressions with percentages may be negative or positive at computed value time.
So, we can only clamp lengths at computed value time, which is what the other
browsers do.
Don't use mem::uninitialized() for making calc values
We had code relying on `nsStyleCoord::set()` being leaky (like it was
before we patched up the calc bindings). Added `nsStyleCoord::null()` for
this use case since it's not possible to construct directly anymore.
