The Intel DDX driver is known to cause troubles with HW-WR and
has been deprecated by most distributions, in favor of the glamor
based "modesetting" driver.

Lets blocklist it. This will mostly affect older/legacy setups.

Note: the xrandr boilerplate code in glxtest will be useful for
better multi-screen detection in a follow up patch. The current
legacy X11 screen detection does not work in composited environments,
always reporting one single big screen with the combined size.
Xrandr allows for correct detection in such setups.

Bug 1728638 - Parameters to set MSIX `Package/Identity/{Name,Publisher}` and `Package/Properties/PublisherDisplayName`. r=bhearsum

This is just rearranging some deck chairs as we hammer out details in

Bug 1728472 - Part 2: Restrict advertised languages in MSIX to allow-list from Windows. r=bhearsum,flod

Windows MSIX packages support a finite set of locales: see
https://docs.microsoft.com/en-us/windows/uwp/publish/supported-languages.
This patch encodes that list in
browser/installer/windows/msix/msix-all-locales.  Two ad-hoc
modifications were necessary: removing 'sr*' (Serbian) and 'uz*'
(Uzbek) in order for the resulting MSIX packages to install.

We distribute all of the langpacks supported by the release channel in
our MSIX, which is encoded in browser/locales/all-locales.  But we
only advertise support in the App manifest for the intersection of
that set and the set of locales supported by Windows.

We do so to avoid the following issue.  Suppose a user manually
installs a langpack that is not supported by Windows, and then updates
the installed MSIX package.  MSIX package upgrades are essentially
paveover installs, so there is no opportunity for Firefox to update
the langpack before the update.  But, since all langpacks are bundled
with the MSIX, that langpack will be up-to-date, preventing one class
of YSOD.

Tier-2 tasks are finished on a helper thread and don't have a
JSContext* to report errors/warnings to. It may be useful for
end-users or engine developers to be notified when a tier-2
task fails and why. This commit implements logging of errors
and warnings by printing to stderr.

An alternative approach would be to get a runnable on the
originating JS thread that reports the errors/warnings using
that *JSContext. I'm not sure the best way to do this, so I
went with the simpler approach for now.

This commit causes ModuleGenerator to report a warning when
we fail to allocate executable memory for a ModuleSegment. This will
get reported in the JS console in addition to the OOM error.

The one tricky change is that entry points to module compilation
needed to be reworked so that they could report warnings even if
an error or OOM was encountered.

Backed out changeset 176469dcdeba (bug 1731154) for causing bc failures on browser_attributed_text.js.

This is a backout of the patch in bug 1581574 in the hope that it will fix the
crashes in bug 1731432.

Previously this write barrier was not required and we relied on the read
barrier, but it seems that may not be sufficient to allow us to mark gray roots
after the first GC slice. There are few ways that the value of a Heap<T> can be
observed without triggering the read barrier, and that could explain what's
happening here.

The contents of JS holders are cleared when they are removed from the holder
map, so that will also trigger the write barrier.

When a page-size that is not auto or square exists the print preview will use
the orientation of this page-size when doing initial reflow. The frontend
applies the orientation to the print settings without updating settings and
causing a second reflow, and the orientation selector is hidden.
