Some debugging reveals that the send_back_unused_buffers() quite often sends empty vectors back to the paint task. This still incurs a communication overhead though. Instead check that the there actually are buffers to send back.

@kenpratt and I moved the URL and IFrame fields from Reflow to LayoutTask, as described in #5466.
This is my first attempt at Rust, so let me know how this is!

There are several optimizations here:
* We make font families atoms, to allow for quicker comparisons.
* We precalculate an FNV hash of the relevant fields of the font style
structure.
* When obtaining a platform font group, we first check pointer equality
for the font style. If there's no match, we go to the FNV hash. Only
if both caches miss do we construct and cache a font group. Note that
individual fonts are *also* cached; thus there are two layers of
caching here.
15% improvement in total layout thread time for Facebook Timeline.

Transition events are not yet supported, and the only animatable
properties are `top`, `right`, `bottom`, and `left`. However, all other
features of transitions are supported. There are no automated tests at
present because I'm not sure how best to test it, but three manual tests
are included.

- Most of util::memory has been moved into profile::mem, though the
`SizeOf` trait and related things remain in util::memory. The
`SystemMemoryReporter` code is now in a submodule
profile::mem::system_reporter.
- util::time has been moved entirely into profile::time.

Cycles were being created in the flow tree since absolutely positioned
descendants had pointers to their containing blocks. This adds
WeakFlowRef (based on Weak<T>) and makes these backpointers weak
references. This also harmonizes our custom Arc<T>, FlowRef, to be
consistent with the upstream implementation.
Fixes#4915.

When a viewport is resized, the computed values for a style containing viewport percentage length units become stale. However, there's no way for those styles to be invalidated after a resize. As a solution, this commit invalidates the computed values cache after a resize has occurred, which is probably over-kill.
A better solution would probably be to track under what conditions computed values remain valid, and invalidate them as indicated.

Only simple alphabetic and numeric counter styles are supported. (This
is most of them though.)
Although this PR adds a sequential pass to layout, I verified that on
pages that contain a reasonable number of ordered lists (Reddit
`/r/rust`), the time spent in generated content resolution is dwarfed by
the time spent in the parallelizable parts of layout. So I don't expect
this to negatively affect our parallelism expect perhaps in pathological
cases.
Reconstructed from #5138 via raw diffing.
