Flatten and simplify Servo's preferences code. In addition, have both
preferences and options passed in as arguments to `Servo::new()` and
make sure not to use the globally set preferences in `servoshell` (as
much as possible now).
Instead of a complex procedural macro to generate preferences, just
expose a very simple derive macro that adds string based getters and
setters.
- All command-line parsing is moved to servoshell.
- There is no longer the concept of a missing preference.
- Preferences no longer have to be part of the resources bundle because
they now have reasonable default values.
- servoshell specific preferences are no longer part of the preferences
exposed by the Servo API.

The containing block for children already has the size coming from the
style and the rules of the parent formatting context, so no need to try
to recompute it.
This allows removing a bunch of functions, and fixes some problems when
the table is a flex item.

It used to be an `AuOrAuto`, turning it into a `SizeConstraint` allows
passing the information about the min and max constraints when the
containing block doesn't have a definite block size.
This will be useful for table layout.
Note that in most cases we were already constructing the containing
block from a `SizeConstraint`, but we were calling `to_auto_or()` to
turn it into an `AuOrAuto`.

Push the interior mutability into enum variants of `Fragment`, so that
they can be cloned. This saves memory in the `Fragment` tree as the
`Fragment` enum is now a relatively wee 16 bytes and the interior parts
can be a variety of sizes. Before, every `Fragment` was the size of the
biggest kind (`BoxFragment` - 248 bytes).
This a step on the way toward incremental layout.

Instead of creating an IPC channel for every fetch, allow cancelling
fetches based on the `RequestId` of the original request. This requires
that `RequestId`s be UUIDs so that they are unique between processes
that might communicating with the resource process.
In addition, the resource process loop now keeps a `HashMap` or `Weak`
handles to cancellers and cleans them up.
This allows for creating mutiple `FetchCanceller`s in `script` for a
single fetch request, allowing integration of the media and video
elements to integrate with the `Document` canceller list -- meaning
these fetches also get cancelled when the `Document` unloads.

This is still not the right approach, because we are not painting
collapsed borders as a single thing. Instead, we are splitting them

looks good for solid borders.

This allows reusing the asynchrnous fetch mechanism that we use for page
resources and is likely a step toward removing the `FetchThread`.
Benefits:
- Reduces IPC traffic during navigation. Now instead of bouncing
between the constellation and the `ScriptThread` responses are sent
directly to the `ScriptThread`.
- Allows cancelling loads after redirects, which was not possible
before.
There is the question of what to do when a redirect is cross-origin
(#23037). This currently isn't handled properly as the `Constellation`
sends data to the same `Pipeline` that initiated the load. This change
doesn't fix this issue, but does make it more possible for the
`ScriptThread` to shut down the pipeline and ask the `Constellation` to
replace it with a new one.

A box is usually sized by the formatting context in which it participates.
However, tables have some special sizing behaviors, and these were in
conflict.
Instead of letting tables attempting to re-resolve their inline table,
which failed to e.g. take flex properties into account or resolve sizing
keywords correctly, now tables will trust the inline size determined by
the parent. They will only floor it by the min-content size, and maybe
shrink the final size due to collapsed columns.

Previously, senders and receivers to different kinds of event loops (the
main `ScriptThread`, different types of workers) used a rust `trait`
mechanism to implement dynamic behavior. This led to having many unused
implementations of this `trait`. This change moves to using an `enum`
based approach for these senders and receivers and removes all of the
dead code.
In addition, to allowing for use of rust's dead code detection, it
simplifies the code a great deal. All of these generic senders and
receivers are moved to the `messaging.rs` file and given proper
documentation.
Finally, empty an `JSTraceable` implementation is made for all
crossbeam `Sender<...>`s to avoid having to manually skip them everytime
they are included in structs. The pre-existing empty `MallocSizeOf`
implementation is used more thoroughly.
Other unecessary wrappers around these senders and receivers are removed
as well.

When laying out a block-level box that avoids floats, if we know that
its size doesn't depend on the available space, we can take a fast path
and only lay it out once. If its size depends on the available space,
we may have to lay it out multiple times, which can be slower.
This patch improves the check for this dependency on the available space.
For example, `min-width: 200px; width: 100px; max-width: stretch` was
previously considered to depend on the available space because of
`max-width`. However, `max-width` is irrelevant when the min size is
greater than the preferred size.
