2020, not yet wired to the rest of layout.
This commit implements an object that handles the 10 rules in CSS 2.1:
https://www.w3.org/TR/CSS2/visuren.html#float-position
The implementation strategy is that of a persistent balanced binary search tree
of float bands. Binary search trees are commonly used for implementing float
positioning; e.g. by WebKit. Persistence enables each object that interacts
with floats to efficiently contain a snapshot of the float list at the time
that object was laid out. That way, incremental layout can invalidate and start
reflow at any point in a containing block.
This commit features extensive use of
[QuickCheck](https://github.com/BurntSushi/quickcheck) to ensure that the rules
of the CSS specification are followed.
Because this is not yet connected to layout, floats will not actually be laid
out in Web pages yet.
Note that unit tests as set up in Servo currently require types that they
access to be public. Therefore, some internal layout 2020 types that were
previously private have been made public. This is somewhat unfortunate.
Part of #25167.
Implement Console grouping APIs.
These are used by Hubs and other sites we want to run.

Do not raise StopIteration: PEP 479
<!-- Please describe your changes on the following line: -->
This fixes `test-tidy` Py3 compatibility, as [PEP 479](https://www.python.org/dev/peps/pep-0479/) says `return` must be used to stop iteration inside generator instead of `raise StopIteration`.
This introduces subtle behavior change where `FileList()` constructor now won't implicitly stop the caller generator when the list is empty. `wpt_lint.py` is modified to explicitly stop when empty, to match the change.

Fix Py3 environment setting failures
<!-- Please describe your changes on the following line: -->
`python3 mach build -d` now proceeds to actual build. Since Gecko landed full Python 3 support, updating mozjs should allow us to drop Python 2 to build Servo. (I still see failures on other commands e.g. `test-tidy`.)

Show the real commit hash for `./servo --version`, not the bundle hash
<!-- Please describe your changes on the following line: -->
Show the real commit hash of the build when run on a bundle commit, rather than showing the bundle's hash.
It gets the real commit hash by extracting it from the bundle commit message, which has the form `Shallow version of commit {sha1}`, where `{sha1}` is the real commit hash.

Support building on Void Linux
Adds support for building on Void Linux.
Since this distribution uses LibreSSL, currently it's not possible to link against it. So this adds `openssl-src` feature to corresponding crates in order to activate `openssl/vendored`.
Automatic activation of this feature on Void is also included in build system.
*Note*: #26117 will activate `openssl/vendored` by default. If that's the case, I will just keep the package names in `./mach`.
