This patch implements the `FontFace` interface, but with some caveats
1. The interface is only exposed on `Window`. Support for Workers will
be handled in the future.
2. The concept of `css-connected` `FontFace` is not implemented, so
`@font-face` rules in stylesheets will not be represented in the DOM.
3. The constructor only supports using `url()` strings as source
and `ArrayBuffer` and `ArrayBufferView` are not supported yet.
A skeleton implementation of the `load` method of `FontFaceSet` is also
implemented in this patch. The intention is to support some web pages
that don't load without this method.

This change exposes a single `InputEvent` type and now there is only a
single delegate method for this `WebViewDelegate::notify_input_event`.
- Clipboard events are now handled as `EditingAction` inpute events. In
the future this can include things like "Select All", etc.
In addition, many parts of the dance to pass these events can now be
simplified due to this abstraction.
- All forwarded events are handled the same way in the `Constellation`,
though they may carry an optional hit test (for events that have a
`point`) which affects which `Pipeline` they are sent to.
- In the `ScriptThread` we now accept these `InputEvents` and use them
everywhere. Now all "compositor events" are "input events".
- This allows removing several data structures which are no longer
necessary.
- We no longer inform the embedder when an event was handled by a
WebView as that was only important for a MDI feature that will
no longer be so important the full-featured `WebView` API.

In addition to some small API changes, this downstream version of
WebRender no longer depends on a very old version of time. This is the
last step toward removing the dependency on `time0.1`.

Instead of creating a type for each `TaskSource` variety have each `TaskSource`
hold the same kind of sender (this was inconsistent before, but each
sender was effectively the same trait object), a pipeline, and a
`TaskSourceName`. This elminates the need to reimplement the same
queuing code for every task source.
In addition, have workers hold their own `TaskManager`. This allows just
exposing the manager on the `GlobalScope`. Currently the `TaskCanceller`
is different, but this will also be eliminated in a followup change.
This is a the first step toward having a shared set of `Sender`s on
`GlobalScope`.

Up until now, Servo was using a very old version of time to get a
cross-process monotonic timestamp (using `time::precise_time_ns()`).
This change replaces the usage of old time with a new serializable
monotonic time called `CrossProcessInstant` and uses it where `u64`
timestamps were stored before. The standard library doesn't provide this
functionality because it isn't something you can do reliably on all
platforms. The idea is that we do our best and then fall back
gracefully.
This is a big change, because Servo was using `u64` timestamps all over
the place some as raw values taken from `time::precise_time_ns()` and
some as relative offsets from the "navigation start," which is a concept
similar to DOM's `timeOrigin` (but not exactly the same). It's very
difficult to fix this situation without fixing it everywhere as the
`Instant` concept is supposed to be opaque. The good thing is that this
change clears up all ambiguity when passing times as a `time::Duration`
is unit agnostic and a `CrossProcessInstant` represents an absolute
moment in time.
The `time` version of `Duration` is used because it can both be negative
and is also serializable.
Good things:
- No need too pass around `time` and `time_precise` any longer.
`CrossProcessInstant` is also precise and monotonic.
- The distinction between a time that is unset or at `0` (at some kind
of timer epoch) is now gone.
There still a lot of work to do to clean up timing, but this is the
first step. In general, I've tried to preserve existing behavior, even
when not spec compliant, as much as possible. I plan to submit followup
PRs fixing some of the issues I've noticed.

This is the start of the organization of types that are in their own
crates in order to break dependency cycles between other crates. The
idea here is that putting these packages into their own directory is the
first step toward cleaning them up. They have grown organically and it
is difficult to explain to new folks where to put new shared types. Many
of these crates contain more than traits or don't contain traits at all.
Notably, `script_traits` isn't touched because it is vendored from
Gecko. Eventually this will move to `third_party`.
