Encourage better documentation patterns
https://github.com/servo/servo/wiki/Glossary is really easy to overlook, so I want to move it in-tree. This also allows us to build a self-perpetuating system where people who are confused by something are encouraged to make a pull request that lets us know about this fact.
Also, I have suspicions that a `docs/` directory is easier to notice than various markdown files scattered around the repository root.

Use constructor pattern instead of separate utility function.
Instead of allowing the Servo HSTS file loading to silently fail, we
should expect that file to always exist and be formatted correctly.
Implement HTMLTextArea.setSelectionRange (continuation of #10007)
Tests on `tests/wpt/web-platform-tests/html/semantics/forms/textfieldselection/textfieldselection-setSelectionRange.html` all pass and the other tests don't panic due to double borrows anymore.

Make `read_resource_file` param simpler and more idiomatic.
`<P: AsRef<Path>>` is also what `File::open` uses as a generic type for
the parameter.

Fix handling of borders and padding for empty/stripped inline flows
This forces fragment generation for empty inline flows, if they have borders or padding. Fixes#10533 and #2001. Also includes fixes for other bugs that were uncovered by this change; see the individual commit messages for detailed explanations. r? @pcwalton

Empty fragments may need to be layed out to draw borders, padding/background,
and insertion points. (Fragments that consist of discardable whitespace and
control characters, on the other hand, can still be discarded.)
This ends up preserving some useless empty fragments. It's possible we could
avoid this by storing some sort of flag on "important" empty fragments, so we
can discard the rest.
