Given that the `customScaleOption` should already be hidden, provided that the browser supports that, this patch also prevents it from being accessible via the keyboard.
As far as my testing goes in various browsers, this doesn't seem to have any ill effects, and note that we're already explicitly ignoring the `custom` value in the `select` event handler.

This patch resolves the responsiveness issues for the toolbar in the
viewer. Depending on the language (for example the Dutch language),
elements could overlap when the viewport size is reduced.
The main issue here is that the CSS rules are unnecessarily complex and
handle lots of different cases (LTR/RTL, displacements for specific
viewport widths, et cetera). By removing this complexity and letting the
browser handle the responsiveness, we not only get simpler CSS rules and
HTML mark-up, but the responsiveness issues are mostly fixed at the same
time. We no longer have to position the elements manually (by setting
their `left` attribute value) anymore.
The following reasoning was used for deciding to remove the "Page: " label, and replace it with a tooltip, from the main toolbar:
- We have no other visible labels in the *main* toolbar (e.g. the Zoom dropdown doesn't have a label, but only a tooltip).
- We already hide the "Page: " label when the viewer is narrow.
- The varying width of the "Page: " label in different locales is already causing issues for many languages, with overlap in the main toolbar as a result.
Trying to create responsive CSS styles that works well in all locales is already difficult, and if we add support for page labels that will only further compound the issues.
- Some PDF viewers (e.g. Adobe Reader, pdfium in Chrome) doesn't show labels in the UI by default.
The outline toggle button has a feature where it can be double-clicked
to expand/collapse all items shown therein. Although this is described
in the FAQ, can go potentially unnoticed. This, however, being a useful
feature, advertise on the tool tip itself.

When Firefox is run in e10s mode, which will soon be the default, the PDF.js zoom dropdown menu doesn't look right. This is apparently because the `<select>` DOM element is rendered in the parent, and that all the necessary style information isn't sent up from the child. See the discussion in https://bugzilla.mozilla.org/show_bug.cgi?id=910022.
Besides this causing the PDF.js UI to *look* worse in e10s, notably it also means that the `customScaleOption` isn't hidden like it ought to be.
To work-around that, this patch utilizes the `hidden` attribute, since https://bugzilla.mozilla.org/show_bug.cgi?id=1242450 at least made that work in e10s.

The sidebar code has, except for minor fixes/additions (such as attachments), been largely untouch for years.
To avoid having a bunch of sidebar code sprinkled throughout viewer.js, this patch moves the sidebar code into a separate file (pdf_sidebar.js), similar to how most other functionality has been moved in the last few years.
Besides simply moving code around, this patch also has the added benefit that we now keep track of the sidebar state (not just opened/closed).
This now makes it possible to handle both `Preferences` *and* `ViewHistory` settings for the sidebar state in a cleaner way, preventing strange and confusing interactions between the two.
Changes `PDFOutlineView`/`PDFAttachmentView` to be initialized once, since we're always creating them, and refactor their `render` methods to instead pass in the `outline`/`attachments`.
For consistency with other "classes", the `PDFOutlineView`/`PDFAttachmentView` are renamed to `PDFOutlineViewer`/`PDFAttachmentViewer`.
Also, make sure that the outline/attachments are reset when the document is closed. Currently we keep the old ones around until the `getOutline`/`getAttachments` API calls are resolved for a new document.
Fixes 6898.
Note that this doesn't prevent the warning for PDF files that *do* ask for a password, e.g. http://async5.org/moz/passwordOU.pdf, but it's not clear to me if/how we could avoid that.
This patch makes the naming consistent with the `TextLayerBuilder`, and also the new `AnnotationLayer`, and should thus help reduce possible confusion when working with the code.
Please note that the files were renamed using `git mv`, in order to preserve blame.
If your Internet Explorer 11 default compatibility settings are set to "I.E 7 Compatibility", the PDF plugin will not load. This fix is the same one used by AngularJS to force the browser to use HTML5 mode.
The line that this patch removes has been commented out since 2012 (!), see commit c8a6a9ba00.
Also, since the patch is trivial, I'm fixing the formatting of a comment to stop [GitHub from marking it with a red color](https://github.com/mozilla/pdf.js/blob/master/web/viewer.html#L394) (and IE from complaining).
The current way that the tabindices are defined, has the unfortunate consequence that adding a single button to the UI might mean having to change almost all tabindices. (This was the case in e.g. PR 4329.)
This patch attempts to avoid that situation happening again, by re-defining the tabindices slightly.
