This patch does not make the necessary replacement in tests. Those changes will be made in a later patch in this stack.
Some additional, related changes are also made in this patch:
cleanupActiveUpdate is being replaced with cleanupDownloadingUpdate and cleanupReadyUpdate. The two new functions currently do very similar things, but separating them will allow us to have each function clean up the right update, once we fully support more than one update per session.
The old mechanism to add something to the update history was for it to be assigned to activeUpdate, and then to assign null to activeUpdate. We now need to assign active updates to be null without adding them to the history. As an example, we need to set downloadingUpdate to null when the download completes, but it shouldn't be added to the history at that point. To address this, an explicit addUpdateToHistory function has been added, and assigning null to either active update variable no longer moves the update to the update history.

This also updates the behavior of the allowDuplicates check:
Instead of only checking if the top dialog is a duplicate, it will now check the whole stack and
skip the dialog open if a duplicate URL is found.
This fixes an issue where callers could alternate between dialogs to bypass the check.

Prior to this patch, PDF.js tracks both its own 'disabled' pref (which is used
by enterprise policy) and whether it is the default handler per the handler
service - but it tracks both in one bool, which determines whether its
streamconverter registers.
Really, what we want is to never use PDF.js if it's preffed off.
However, if there is some other default, it should be acceptable to use PDF.js
in some circumstances, like for <embed> or <object>s where otherwise we
would show no content at all.
Even for toplevel PDFs, if the user has configured Firefox to open PDFs in
an external helper app which is Firefox (which is currently an easy mistake
to make in the unknownContentType dialog), or has it set to the OS default,
but has changed their OS default to Firefox, we really still want to open
those PDFs with PDF.js.
This patch fixes all of this by splitting out the pref tracking from the
handler state tracking. Only the pref will completely disable PDF.js.
Then, in the streamconverter code, we check whether PDF.js should be used for
PDFs, and if there's a misconfiguration that we can correct. This code is
invoked from the parent process when we load PDFs in frames or toplevel
documents, and will prevent us from invoking PDF.js in the child if the user
would prefer that not to happen.
As a driveby, this cleans up how we track the pref inside PDF.js, and how we
get notified of changes to the handler - we were missing changes made in the
unknown content type dialog, so it seemed worth making it generic.

Raw Cr.ERROR don't get stack information, same as throwing JS literals instead
of `new Error()`s.
This was done automatically with a new eslint rule that will be introduced in
the next commit. One instance of a raw Cr.ERROR was not replaced since it is
used in a test that specifically checks the preservation of raw Cr values in
XPCJS. The rule will be disabled for that instance.

The -*- file variable lines -*- establish per-file settings that Emacs will
pick up. This patch makes the following changes to those lines (and touches
nothing else):
- Never set the buffer's mode.
Years ago, Emacs did not have a good JavaScript mode, so it made sense
to use Java or C++ mode in .js files. However, Emacs has had js-mode for
years now; it's perfectly serviceable, and is available and enabled by
default in all major Emacs packagings.
Selecting a mode in the -*- file variable line -*- is almost always the
wrong thing to do anyway. It overrides Emacs's default choice, which is
(now) reasonable; and even worse, it overrides settings the user might
have made in their '.emacs' file for that file extension. It's only
useful when there's something specific about that particular file that
makes a particular mode appropriate.
- Correctly propagate settings that establish the correct indentation
level for this file: c-basic-offset and js2-basic-offset should be
js-indent-level. Whatever value they're given should be preserved;
different parts of our tree use different indentation styles.
- We don't use tabs in Mozilla JS code. Always set indent-tabs-mode: nil.
Remove tab-width: settings, at least in files that don't contain tab
characters.
- Remove js2-mode settings that belong in the user's .emacs file, like
js2-skip-preprocessor-directives.
