* We make ProcessRuntime aware of the Win32k Lockdown process mitigation
policy. When Win32k is disabled, we perform process-wide COM initialization

pieces in ProcessRuntime.
* We move some Gecko-specific stuff into MOZILLA_INTERNAL_API guards so that
ProcessRuntime is usable outside of xul.dll (I will be needing it for the

* Another thing that might happen with the launcher process is that, under
error conditions in the launcher, we create a ProcessRuntime object on a
background thread for the purposes of telemetry logging, but we also allow
the main thread to proceed to start as the browser. This could result in a
scenario where the main thread, as the browser process, is attempting to
instantiate its ProcessRuntime and ends up racing with the launcher process's
telemetry thread which has its own ProcessRuntime. To account for this
situation, we add mutual exclusion to the process-wide initialization code.
We host this part inside mozglue since that state is shared between both
firefox.exe and xul.dll.
* We clean up ProcessRuntime::InitializeSecurity by using Vector to set up

Bug 1514594: Part 3a - Change ChromeUtils.import to return an exports object; not pollute global. r=mccr8
This changes the behavior of ChromeUtils.import() to return an exports object,
rather than a module global, in all cases except when `null` is passed as a
second argument, and changes the default behavior not to pollute the global
scope with the module's exports. Thus, the following code written for the old
model:
ChromeUtils.import("resource://gre/modules/Services.jsm");
is approximately the same as the following, in the new model:
var {Services} = ChromeUtils.import("resource://gre/modules/Services.jsm");
Since the two behaviors are mutually incompatible, this patch will land with a
scripted rewrite to update all existing callers to use the new model rather
than the old.

In bug 1507365, we introduced the ability of nested label children of toolbar buttons to provide the accessible name for a xul:toolbarbutton element. However, the XBL of xul:toolbarbutton causes the creation of a label accessible even if no xul:label child is present, and only the label attribute is being used. The nsIAccessibleText interface on such labels is, however, completely broken. This causes NVDA's mouse tracking, which always uses the deepest nested child, to fail. As a result, when hovering over Hamburger menu items, the announcement would be wrong, e. g., lag one behind the actual button the mouse is hovering over.
To fix this, we only accept xul:label children if they come from real XUL markup, not from the label attribute and the XBL creating the label. This means that some of the test changes from bug 1507365 have to be reverted to accommodate the new old behavior. But the new test for an actual label child still passes.

There's a few subtle behavior changes here, which I'll try to break down in the
commit message.
The biggest one is the EditableDescendantCount stuff going away. This
was added in bug 1181130, to prevent clicking on the non-editable div from
selecting the editable div inside. This is problematic for multiple reasons:
* First, I don't think non-editable regions of an editable element should
be user-select: all.
* Second, it just doesn't work in Shadow DOM (the editable descendant count is
not kept up-to-date when not in the uncomposed doc), so nested
contenteditables behave differently inside vs. outside a Shadow Tree.
* Third, I think it's user hostile to just entirely disable selection if you
have a contenteditable descendant as a child of a user-select: all thing.
WebKit behaves like this patch in the following test-case (though not Blink):
https://crisal.io/tmp/user-select-all-contenteditable-descendant.html
Edge doesn't seem to support user-select: all at all (no pun intended).
But we don't allow to select anything at all which looks wrong.
* Fourth, it's not tested at all (which explains how we broke it in Shadow DOM
and not even notice...).
In any case I've verified that this doesn't regress the editor from that bug. If
this regresses anything we can fix it as outlined in the first bullet point
above, which should also make us more compatible with other UAs in that
test-case.
The other change is `all` not overriding everything else. So, something like:
<div style="-webkit-user-select: all">All <div style="-webkit-user-select: none">None</div></div>
Totally ignores the -webkit-user-select: none declaration in Firefox before this
change. This doesn't match any other UA nor the spec, and this patch aligns us
with WebKit / Blink.
This in turn makes us not need -moz-text anymore, whose only purpose was to
avoid this.
This also fixes a variety of bugs uncovered by the previous changes, like the
SetIgnoreUserModify(false) call in editor being completely useless, since
presShell->SetCaretEnabled ended in nsCaret::SetVisible, which overrode it.
This in turn uncovered even more bugs, from bugs in the caret painting code,
like not checking -moz-user-modify on the right frame if you're the last frame
of a line, to even funnier bits where before this patch you show the caret but
can't write at all...
In any case, the new setup I came up with is that when you're editing (the
selection is focused on an editable node) moving the caret forces it to end up
in an editable node, thus jumping over non-editable ones.
This has the nice effect of not completely disabling selection of
-moz-user-select: all elements that have editable descendants (which was a very
ad-hoc hack for bug 1181130, and somewhat broken per the above), and also
not needing the -moz-user-select: all for non-editable bits in contenteditable.css
at all.
This also fixes issues with br-skipping like not being able to insert content in
the following test-case:
<div contenteditable="true"><span contenteditable="false">xyz </span><br>editable</div>

I think this yields way better behavior in all the relevant test-cases from bug
1181130 / bug 1109968 / bug 1132768, shouldn't cause any regression, and the
complexity is significantly reduced in some places.
There's still some other broken bits that this patch doesn't fix, but I'll file
follow-ups for those.

Creates the HTML Caption accessible from the markup map, but only if it's the first caption. Other caption elements are ignored as before.
This also creates caption accessibles for those captions that have been collapsed to zero height and width via CSS.

There's a few subtle behavior changes here, which I'll try to break down in the
commit message.
The biggest one is the EditableDescendantCount stuff going away. This
was added in bug 1181130, to prevent clicking on the non-editable div from
selecting the editable div inside. This is problematic for multiple reasons:
* First, I don't think non-editable regions of an editable element should
be user-select: all.
* Second, it just doesn't work in Shadow DOM (the editable descendant count is
not kept up-to-date when not in the uncomposed doc), so nested
contenteditables behave differently inside vs. outside a Shadow Tree.
* Third, I think it's user hostile to just entirely disable selection if you
have a contenteditable descendant as a child of a user-select: all thing.
WebKit behaves like this patch in the following test-case (though not Blink):
https://crisal.io/tmp/user-select-all-contenteditable-descendant.html
Edge doesn't seem to support user-select: all at all (no pun intended).
But we don't allow to select anything at all which looks wrong.
* Fourth, it's not tested at all (which explains how we broke it in Shadow DOM
and not even notice...).
In any case I've verified that this doesn't regress the editor from that bug. If
this regresses anything we can fix it as outlined in the first bullet point
above, which should also make us more compatible with other UAs in that
test-case.
The other change is `all` not overriding everything else. So, something like:
<div style="-webkit-user-select: all">All <div style="-webkit-user-select: none">None</div></div>
Totally ignores the -webkit-user-select: none declaration in Firefox before this
change. This doesn't match any other UA nor the spec, and this patch aligns us
with WebKit / Blink.
This in turn makes us not need -moz-text anymore, whose only purpose was to
avoid this.
This also fixes a variety of bugs uncovered by the previous changes, like the
SetIgnoreUserModify(false) call in editor being completely useless, since
presShell->SetCaretEnabled ended in nsCaret::SetVisible, which overrode it.
This in turn uncovered even more bugs, from bugs in the caret painting code,
like not checking -moz-user-modify on the right frame if you're the last frame
of a line, to even funnier bits where before this patch you show the caret but
can't write at all...
In any case, the new setup I came up with is that when you're editing (the
selection is focused on an editable node) moving the caret forces it to end up
in an editable node, thus jumping over non-editable ones.
This has the nice effect of not completely disabling selection of
-moz-user-select: all elements that have editable descendants (which was a very
ad-hoc hack for bug 1181130, and somewhat broken per the above), and also
not needing the -moz-user-select: all for non-editable bits in contenteditable.css
at all.
This also fixes issues with br-skipping like not being able to insert content in
the following test-case:
<div contenteditable="true"><span contenteditable="false">xyz </span><br>editable</div>

Simply decouple the check for the checked attribute from the one for the type attribute.

When determining if an author provided an empty alt attribute versus no alt attribute at all, our image accessible name is either an empty string or a null string. Screen readers can then choose to guess the name from the source if the author did not explicitly provide an empty alt text and thus marked the image as decorative.
The accessible handler for the Windows remote processes did not account for this distinction, always returning what appeared to be an empty string. This was found while determining why NVDA wasn't guessing the SRC from a non-labelled graphical link. NVDA checks to see if the name returned by the link accessible is null, and then decides to look for the graphical children if that is the case.

Toolbar buttons in XUL can now have labels inside them to provide the actual caption for the button. Adjust the accessibility module to allow label elements as acceptable children for the toolbarbutton element so the algorithm can pick up their text for the button's name.

(Unless there were other profiler actions, as I'm not sure yet whether it would
be safe to skip them when the profiler is paused; another bug should
investigate that.)

This patch removes the dom.webcomponents.shadowdom.enabled pref and all its
references, including the following functions:
* nsContentUtils::IsShadowDOMEnabled()
* nsIDocument::IsShadowDOMEnabled()
* nsDocument::IsShadowDOMEnabled(JSContext* aCx, JSObject* aGlobal)
* nsDocument::IsShadowDOMEnabled(const nsINode* aNode)
* nsTextNode::IsShadowDOMEnabled(JSContext* aCx, JSObject* aObject)
This function is renamed and updated to nsDocument::IsCallerChromeOrAddon():
* nsDocument::IsShadowDOMEnabledAndCallerIsChromeOrAddon(JSContext* aCx, JSObject* aObject)
I didn't change the tests that load Shadow DOM tests in an iframe, in the interest of keeping hg annotation history.
