We previously (in bug 1491235) adjusted some utility code to make
layout-contained frames behave as if they have no baseline.
But that's not sufficient. To make frames fully report lack-of-a-baseline,
we now do the following for layout-contained frames, as of this patch:
(a) We now leave the ReflowOutput outparam's BlockStartAscent member at its
default value (which is what we do for frames without a baseline like
e.g. nsCheckboxRadioFrame and nsHTMLCanvasFrame). And if the parent cares
about the baseline, it'll then ask directly, using a baseline getter.
(b) We now return 'false' in more implementations of bool-returning
baseline-getter-methods (where 'false' indicates 'no baseline').
(c) We now return the margin-box-bottom edge, in the nscoord-returning
'GetLogicalBaseline()' getter method. (We typically do this by deferring
to the inherited method, which ultimately comes from nsFrame's
implementation). It's appropriate to use the margin-box-bottom edge when
there's no baseline, per the definition of 'vertical-align: baseline',

In particular:
- In contain-layout-suppress-baseline-002.html, the test currently indirectly
relies on the 50px-tall-canvas being the tallest thing in each flex
container. This isn't robustly true (and in fact on windows, the textarea is
taller at 50.8px tall). So I'm adjusting this test so that it no longer has a
hardcoded flex container size and no longer depends on this.
- In contain-layout-baseline-005.html and its reference case, we need to
explicitly specify 'vertical-align:baseline' to test baseline-alignment,
because some of its tested form controls have other UA-stylesheet-provided
default values of 'vertical-align'.
(e.g. <select multiple> defaults to 'vertical-align:text-bottom")
- Also: in that same test, we need to reduce the width of the an <input>
textfield -- otherwise, it and the other elements on its line may not fit and
may linewrap, which prevents us from effectively testing baseline-alignment
on the linewrapped element.
- In contain-layout-button-001.html, the expectation was not correct. Before
this patch, the test expects that a layout-contained button will have the
same baseline as an empty button, and that's an invalid expectation. An empty
button uses a point inside of its content-box as its baseline, whereas a
layout-contained element *has no baseline*, which means that it does
'vertical-align:baseline' alignment by aligning its own margin-bottom edge
with the parent's baseline, per
https://drafts.csswg.org/css2/visudet.html#propdef-vertical-align
So, I'm amending the test to have this expectation and updating its meta tags
to reference the updated expectation and with a reference to that spec text.
Firefox fails the amended contain-layout-button-001.html test, so this patch
adds a .ini file to reflect that failure. The next patch in this series will
fix our implementation to make us pass the test, and will remove the .ini file.
Chrome also fails the amended contain-layout-button-001.html tests, and I filed
https://bugs.chromium.org/p/chromium/issues/detail?id=965740 on them with an
explanation.

This includes style system and layout update. I add 3 extra reftests
because the original tests use ray() function as the offset-path, but we
don't support it. It'd be better to add tests using a different type of
offset-path.

This test is used to ensure that we queue 'honor user preferences for automatic text track selection' as a marco task, not a mirco task.
In this test, we would trigger a media event before queuing a text track selection task, and check the text track's mode to know whether the text track selection runs after the task for media event.

This adds an android_emulator_wrench.py script that uses mozharness to
control the Android emulator, and run the wrench reftests. It has an
associated wrench.py config script which is similar to existing android
config scripts.
The android_emulator_wrench script is structured a little differently
from other android mozharness scripts, mostly for two reasons:
1) I tried hard to make it locally runnable by developers, using
./mach python. This allows develpers to more easily reproduce the
setup that runs in automation, and does so without duplicating a lot
of code.
2) I also tried to make the script use fewer of what I consider to be
"opaque" mozharness features, like the actions list which can run
hard-to-find preflight and postflight functions. Instead of treating
mozharness like a framework and filling in some functions for it to
invoke as part of it's grand plan, I treat it more like a library and
specifically the functions I want in the order that I want, which
makes it easier for novice developers to debug problems.
As part of writing this script I extracted a few helper functions and made
some minor changes to existing android/adb mozharness machinery, but these
are all simple refactorings and should introduce no functional change.

We used to use 2 rAFs to stop the load event from racing with
onmessage event, but this was not the proper solution and it was
still racy, especially after Bug 1534012 is landed. So we fixed it
by instead letting racy postMessage to be sent, we wait for the
proper postMessage to be sent, and the test would automatically
timeout if the proper postMessage failed to sent.
