To actually make the multiprocess communication work, we'll need to
reroute the task creation to the pipeline or the compositor. But this
works as a first step.
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.
Borrow the QueueData for WorkQueue::run.
This allows us to get rid of the raw pointers and unsafe dereferencing in
the parallel layout implementation.

layout: Disable parallel display list building by default.
I've never see it result in a speedup. Actually, I don't think I've seen
it result in anything better than a 50% slowdown. The arithmetic
intensity is just too low, at least with the current algorithm.
Parallel DL building can still be enabled with a debug flag if the
algorithm is improved.

The util component specified fnv and smallvec as dependencies and publicly
reexported both of them. Several other components utilized these reexports,
presumably because fnv and smallvec used to live in the tree so reexporting
made the transition easier.
These indirect dependencies through the util component are unnecessary.
This commit removes the fnv & smallvec crate reexports in the util component.
It exchange, it adds fnv & smallvec as dependencies to non-util components
wherever needed. Finally, it removes the fnv dependency from util as it is not
utilized anywhere in the util component.

Reasons behind existing unstable features:
alloc / OIBIT : For deque (which was just copied from rust's source)
collections:
- `[T].tail()`
- `to_lowercase()`
core:
- `FnBox`
- `intrinsics::breakpoint()`
exit_status: for setting exit status
path_ext: for `is_dir` and `exists()` (can be done in other ways)
step_by/step_trait
std_misc:
- Thunk
- DefaultState and other hasher stuff
zero_one: `num::One`
