* Moves the sidebar into the header so that user can tab directly from
the sidebar button into the sidebar (when open).
* Because the sidebar is absolutely positioned inside the header and the
header applies a top-margin, we need to adjust the top position
calculation for the sidebar.
* Removes the checkbox from the accessibility tree through CSS `display:
none;` instead of HTML attributes.
* Given that the checkbox is not able to receive focus, the
`#mw-sidebar-checkbox:focus ~ .mw-header .mw-checkbox-hack-button` CSS
rule is obsolete and moved instead to the label button. An additional
outline: 0 rule was added to remove the dotted outline that Firefox
applies.
* Makes the "Skip to navigation" jump link point to the sidebar now.
After the sidebar has been tabbed through, the rest of the navigation
can be tabbed to.

Hide checkbox from AT by adding `aria-hidden="true" to checkbox
and disable tabbing in via tabindex="-1". Both attributes are temporarily
added and might be removed when the checkbox receives `display: none` in
upcoming patch.
Add
- `role="button"`,
- `aria-controls` and
- `tabindex="0"
to button turned label for ATs via `role` definition, make it focusable
and use `aria-controls` for connection to sidebar id.

The exact search input element as target focus the searchbox. It saves
AT users a user action, while still remaining read out due to connected
label in screen readers.

`[role]`s are retained for now as they are harmless although
redundant when added to HTML5 elements.
`role="contentinfo"` on `footer` is a special case to address
a known VoiceOver bug.

Keys prefixed with msg- should relate to i18n keys. Fix the existing
template variables where that's not the case.

Using 'skin' as entrance point files, similar to already existing
convention in MediaWiki land with 'skin.json' or 'SkinVector.php' as
example in Vector skin. Replacing Apache inspired 'index' convention.
Also renaming legacy to 'skin-legacy' to be clear on file base that it's
a modification of 'skin'.
