Register/unregister memory reporters in a better place.
By doing this on either side of the call to the relevant tasks' start()
method, we don't need to store the mem::ProfilerChan or the reporter
name in the task itself.

Implement Range#insertNode
Gecko doesn't really follow the spec but it seems to throw a HierarchyRequest error when parent is null.
Any ideas who I should talk to about fixing the spec to account for the null checks?

It is a field that is used a function argument. Given that the control flow
is not quite the same, and we can't add an argument to Send, I opted for a
separate function.
Wire up the JS engine's memory reporting.
SpiderMonkey provides an extremely fine-grained breakdown of memory
usage, but for Servo we aggregate the measurements into a small number
of coarse buckets, which seems appropriate for the current level of
detail provided by Servo's memory profiler. Sample output:
```
| 17.41 MiB -- url(file:///home/njn/moz/servo/../servo-static-suite/wikipedia/Guardians%20of%20the%20Galaxy%20(film)%20-%20Wikipedia,%20the%20free%20encyclopedia.html)
| 7.32 MiB -- js
| 3.07 MiB -- malloc-heap
| 3.00 MiB -- gc-heap
| 2.48 MiB -- used
| 0.34 MiB -- decommitted
| 0.09 MiB -- unused
| 0.09 MiB -- admin
| 1.25 MiB -- non-heap
```
Most of the changes are plumbing to get the script task communicating
with the memory profiler task.

Don't crash when Firefox doesn't send autoMargins.
Firefox Developer Tools doesn't always send autoMargins, as seen in this message:
{"type":"getLayout","node":"node14","to":"pageStyle9"}
So don't use unwrap.

This commit introduces the `serde` dependency, which we will use to
serialize messages going between processes in multiprocess Servo.
This also adds a new debugging flag, `-Z print-display-list-json`,
allowing the output of display list serialization to be visualized.
This will be useful for our experiments with alternate rasterizers.
