The ahem font should always be a multiple of 5px and a minimum size
of 20px for reliable results [1]. In particular, on some macs, using
the default size of 16 results in a reported metric of 16 x 17 from
the OS. This is currently working, but breaks when WR is updated to
do pixel snapping in world space.
[1] http://testthewebforward.org/docs/test-style-guidelines.html#special-fonts
The height test is removed in mime_sniffing_font_context because of rounding
changes in app_units. The rest of that test is still useful though, given it
will timeout if the font fails to be sniffed.

<!-- Please describe your changes on the following line: -->
This patch fixes how network errors are handled during page loads: they would not be reported and cause crashes before, and do not anymore.

Prevent crashing when a link tag has two or more in-flight requests (fix for issue #15101)
<!-- Please describe your changes on the following line: -->
The `HTMLLinkElement::set_stylesheet` function now checks whether there already is a stylesheet, and if there is, calls `Document::invalidate_stylesheets` after modifying `self.stylesheet`.
This PR also includes a minimal WPT that causes the panic.
This is fundamentally a timing issue, so while this fix prevents the crash, it does not fix the underlying issue. Making a <link> element send a second request before the first can finish and then getting the two stylesheet responses out-of-order will apply the wrong stylesheet, as demonstrated with https://gist.github.com/SwagColoredKitteh/2c24c7fac635445042eda4a30e10420e.

Fix margin size calculation for TableWrapper
<!-- Please describe your changes on the following line: -->
Fixes inline size calculation for TableWrapper. The table's width was always reaching the inline size equation solver as a specified variable, which was causing the system to be overdetermined when there was a margin specified for the table, and this caused the overflow reported in #12748. The fix consists in handling three cases when the table's width is not specified: if the preferred size of all columns fits, it is returned; if the minimum size does not fit, it is returned instead (it will overflow), otherwise, it is returned as a free variable (that should be solved together with the margin to some value above the minimum width and below the preferred width).

Make offset parent queries less buggy.
<!-- Please describe your changes on the following line: -->
Offset parent queries, which are used in the getters for HTMLElement's `offsetParent`, `offsetTop`, `offsetLeft`, `offsetWidth`, and `offsetHeight`, are pretty busted. The most egregious bug is that, as reported in #12939, inline elements are treated as if they're not present in the document. This PR fixes that and all of the other bugs I could trace directly to the offset parent query code, but `offsetTop` and `offsetLeft` are still unreliable in certain circumstances for reasons I haven't looked into (#13708). Inline elements with no content are still treated as not present due to #13982, so #13944 isn't fixed with this PR, either.

Only create scrolling overflow regions when necessary
Only create scroll roots for overflow regions when the overflow region
is actually larger than the container size. This prevents creating
scrolling roots for elements that do not have overflow scroll as a
side-effect of the way their height and width is defined. For example,
tables should never respect overflow:scroll since their height and
width should always be large enough to prevent overflow. This also
decreases the size and complexity of the display list in many other
circumstances.
As part of this change, transformed overflow calculation is moved from
display list construction to layout. This should mean that overflow is
handled more accurately earlier.
Fixes#14574.

Fix the incrmental reflow behavior of text-overflow
This patch allows Servo to incrementally reflow truncated fragments correctly.
* The untruncated version of a fragment is preserved, and when incrementally reflowing, the untruncated version is what gets reflowed. If it needs truncated, it will get truncated again.
* The ellipsis fragments are skipped when incrementally reflowing a line. If it is still needed, it will be recreated.
