The old code assumes that it's OK to use nsAString::BeginWriting() to write
past the string's logical length if the string has enough capacity. This is
bogus, because the string doesn't know of data written past its logical
length.
The BulkWrite API has been created precisely for this purpose and allows
orderly capacity-aware low-level writes to the string.

nsAutoCopyListener is a singleton class but refcountable and a selection
listener. nsFrameSelection adds it to only normal Selection when it's on
macOS or it's enabled by the pref. Additionally, it's always first selection
listener since it's added immediately after Selection instance is created.
So, we can make it a static class, and normal Selection instance should have
a bool to decide whether it should notify nsAutoCopyListener of its changes.
Then, we can save the cost of grabbing it with local RefPtr and the virtual
call.
Additionally, this patch renames nsAutoCopyListener to mozilla::AutoCopyListener
and optimizes constructor of nsFrameSelection (using bool var cache to retrieve
the pref, avoid retrieving the pref on macOS).

This moves all the node-specific reporting to nsIDocument.
OrphanReporter delegates all the reporting to that and then returns the sum of
all sizes, which is not ideal but was pre-existing.
Also, I moved the main mStyleSheets size reporting to DocumentOrShadowRoot for
it to be shared between document and ShadowRoot.
I'll add memory reporting for the computed stylesheet maps and such in the
ShadowRoot in a followup.
I went through all the XBL bindings, though it seems I could just use
GetBindingWithContent(), since according to:
https://searchfox.org/mozilla-central/rev/55da592d85c2baf8d8818010c41d9738c97013d2/dom/xbl/nsXBLBinding.cpp#615
We don't allow multiple bindings to contribute anon content. Anyway it was the
same amount of code...

This patch removes the 'ScreenOrientationInternal' type from
dom/base/ScreenOrientation.h and moves it into the
HalScreenConfiguration.h header, renaming it simply to 'ScreenOrientation'
in the process. This has several knock-off effects:
- It allows files that needed ScreenOrientationInternal to include a much
smaller header than before
- It greatly reduces the number of headers pulled in when including Hal.h
- It clarifies the role of the type. The 'Internal' part in the name had
nothing to do with it being part of the implementation. The type was public
and called that way only to avoid clashing with the 'ScreenOrientation'
class. Since we moved it into a different namespace it can be renamed
safely.
- It allows a file that was manually re-declaring 'ScreenConfigurationInternal'
type to use the original one
- Finally this fixes a few files which were missing headers they actually
required but that would still build because unified compilation put them into
units that already had those headers thanks to ScreenConfiguration.h

When `document.blockParsing()` is called, the nsIParser is suspended
until the document is unblocked. For about:blank documents, this is a
nsParser.
When a document is unblocked, nsParser::ContinueInterruptedParsingAsync
is invoked, which delegates its implementation to nsIContentSink, which
is a nsHTMLContentSink for about:blank documents. Due to a missing
implementation of nsHTMLContentSink::ContinueInterruptedParsingAsync,
the parser was never resumed, causing bug 1465388 and bug 1407501.
This patch fixes the problem, by implementing the required method (and
using a load blocker to ensure that the (about:blank) document does not
finish before the parser finishes).
This patch is tested through extension tests: Currently document_start
stylesheets always activate the parser blocker, and document_start
scripts trigger the parser blocker when the script has not been
preloaded yet (e.g. at the first run).
Before this patch, the test failed due to the assertion failure as
reported in the linked bugs. After this patch, the tests pass.

libprio does not currently build with MSVC (since it only supports
C90 as a compiler), this is being worked on upstream at https://github.com/mozilla/libprio/issues/17
As we are almost certainly not going to ship Firefox build with MSVC anymore,
let's disable this to get it working on this Tier-2 platform.

This is a regression from bug 1450250, which removed a if (!GetCx()) early
return in this function.
That early return was wrong, both because it prevented elements that were in
shadow trees from targeting other elements, but also because that check was not
present in AfterSetAttr, which means that dynamic updates to the attribute would
work.
Pass the SVGAnimationElement itself to resolve references. That's what we do for
attribute mutations, and also it's the same behavior we have, since the ID
lookup IDTracker does only depends on containing shadow root and containing
document, and that's invariant between a kid and it's DOM parent.
Some other code has been updated to take references instead of pointers so the
null-safety of those methods is explicit.

For reasions which are unclear, MSVC does not recognize the declaration and
definition of ThenWithCycleCollectedArts as matching in their previous form.
Changing both to use the same template `using` declaration for the entire
return type fixes this.
MSVC also has problems with the previous use of std::forward, which is fixed
by explicitly coercing smart pointers to their equivalent pointer types, and
moving any other type.
