This should help us better understand the actual underlying cause of frequent CI failures like #13509. In particular, we will be able to state with confidence whether an IPC message is being dropped while the font cache thread is still alive, or whether the dropped sender was in a message that was in the queue after the font cache thread was shutdown.

Lazy load fonts in a FontGroup
The first commit message explains this so I'll just copy it here:
---
This is a step towards fixing #17267. To fix that, we need to be able to
try various different fallback fonts in turn, which would become
unweildy with the prior eager-loading strategy.
Prior to this change, FontGroup loaded up all Font instances, including
the fallback font, before any of them were checked for the presence of
the glyphs we're trying to render.
So for the following CSS:
font-family: Helvetica, Arial;
The FontGroup would contain a Font instance for Helvetica, and a Font
instance for Arial, and a Font instance for the fallback font.
It may be that Helvetica contains glyphs for every character in the
document, and therefore Arial and the fallback font are not needed at
all.
This change makes the strategy lazy, so that we'll only create a Font
for Arial if we cannot find a glyph within Helvetica. I've also
substantially refactored the existing code in the process and added
some documentation along the way.
---
I've added some tests in the second commit, but it required quite a bit of gymnastics to make it possible to write such a test. I'm not sure if the added complexity to the production code is worth it?
On the other hand, having this infrastructure in place may be useful for testing future changes in this area, and also possibly brings us a step closer to extracting a library as discussed in #4901. (What I mean by that is: it reduces coupling between `FontCacheThread` and `FontContext` -- the latter would have a place in such a library, the former wouldn't.)

This correctly implements the boldness and stretchiness properties for Freetype fonts. This also modifies the metric used to select fonts so that it takes account of stretchiness and italicness instead of just boldness. Finally there is a test of font selection (and thereby that fonts are having their boldness/italicness correctly read).
These were originally part of an old and abandoned pull request. I've rebased the changes and modified them to make them work with some name changes.

Issue #17321. Under Linux, using "font-family: sans-serif" previously
caused Servo to select the "UltraLight" face (of DejaVu Sans). There were
two reasons for this:
1. Font weight was only retrieved from the OS/2 table for bold faces.
This neglected to retrieve the weight information for "lighter than
normal" weight faces. This meant that the UltraLight face appeared as
normal weight, and was selected.
2. Retrieval of font stretch information from the OS/2 table was not
implemented at all.

This PR is the final one in a chain of PRs that tries to make a breaking change to `core-foundation`. This PR makes sure Servo only use the new, not yet released `core-foundation 0.5.0`. The changes in `core-foundation` and why it is not yet published can be read in the comments on this PR: https://github.com/servo/core-foundation-rs/pull/132
Basically we want all of Servo (and deps) to be ready for a fairly swift upgrade from `core-foundation` `0.4.6` to `0.5.0` once it's released, so we don't end up in some state where we depend on, and have to maintain both, for an extended period of time.
This PR is **not ready for merge** in its current state. The following must be done first:
- [x] Merge https://github.com/servo/core-foundation-rs/pull/132 and publish.
- [x] Merge https://github.com/servo/core-graphics-rs/pull/110 and publish.

- [x] Remove the commit in this PR that temporarily adds patch entries to `Cargo.toml`.
- [x] Update Cargo.lock again to not point to my feature branches.
For some of the dependencies I might accidentally have bumped the version as if it was a breaking change when it in fact wasn't. It was a bit messy to figure out all the details in so many and large crates. But hopefully I did not do the inverse, only bump the patch version where the change actually broke something.
Ping @jdm and @nox who have been the ones commenting on the initial PR.

Now supported are the CSS properties:
* background-attachment (except for local value, see #19650)
* background-clip

* background-position-x/y
* background-repeat
* background-size
It should be noted that backgrounds are not clipped to
rounded border corners.
(This was done before but worked only in simple cases)

Some cleanup in display_list_builder.rs related to gradient

Adds two wpt tests for tiled gradients.

Some glitches can be seen in the attached file. I am unsure what the exact intended semantics of [`push_gradient`](https://doc.servo.org/webrender_api/struct.DisplayListBuilder.html#method.push_gradient) are and want to ask the webrender team before building in "workarounds" for the missing gradients.

Servo currently uses `heapsize`, but Stylo/Gecko use `malloc_size_of`.
`malloc_size_of` is better -- it handles various cases that `heapsize` does not
-- so this patch changes Servo to use `malloc_size_of`.
This patch makes the following changes to the `malloc_size_of` crate.
- Adds `MallocSizeOf` trait implementations for numerous types, some built-in
(e.g. `VecDeque`), some external and Servo-only (e.g. `string_cache`).
- Makes `enclosing_size_of_op` optional, because vanilla jemalloc doesn't
support that operation.
- For `HashSet`/`HashMap`, falls back to a computed estimate when
`enclosing_size_of_op` isn't available.
- Adds an extern "C" `malloc_size_of` function that does the actual heap
measurement; this is based on the same functions from the `heapsize` crate.
This patch makes the following changes elsewhere.
- Converts all the uses of `heapsize` to instead use `malloc_size_of`.
- Disables the "heapsize"/"heap_size" feature for the external crates that
provide it.
- Removes the `HeapSizeOf` implementation from `hashglobe`.
- Adds `ignore` annotations to a few `Rc`/`Arc`, because `malloc_size_of`
doesn't derive those types, unlike `heapsize`.

This trades quite a bit of complicated code in Servo for few more
messages and a significant performance improvement. In particular,
WebRender can search the entire display list at once instead of
ping-ponging down the pipeline tree. This allows us to send mouse
events to the correct pipeline immediately.
