The CSS property `background-attachment: fixed` is disabled in some mobile browsers for performance reasons. So here, the fix increases the breakpoint where the `background-attachment: fixed` is applied to the front page images. Doing this removes the fixed backgrounds and the issue from all smaller screens, but the downside is that it also removes the fixed backgrounds from smaller laptops. It's also possible future devices could fall into this breakpoint, but this seems to be the most practical solution.

The combination of font-size and weight for post navigation made lower case "i"s illegible in some cases. Using `15px` seemed to be the best choice all around. Also adjusts the spacing around the arrows a bit, since they touch the text on small screen sizes.

This also reduces the number of browsers detected and patched with this fix. Most modern browsers have patched this common bug, where an anchor link does not move focus when clicked. Twenty Seventeen will only worry about older versions of Internet Explorer in this regard.

In -r39124, some additional issues were introduced:
* The 'overflow: hidden' on the `.site-header;` was added to prevent a side-scrolling issue, but it ended up cutting off the menu. It looks like the cause of the side-scroll was related to how the scroll down icon was rotated, so it's addressed by rotating the icon and not the `<a>`.
* Also, `min-height` doesn't play well with `display: table;` in Firefox. So it's addressed with just `height`.

* Makes sure the page layout setting also applies to pages, and is not completely hidden from them when a sidebar widget is present. Pages do not have a sidebar, so that was incorrect.
* Updates description in Customizer for brevity and accuracy.
* Applies setting to archive pages as well.
* Updates CSS to reflect changes.

* Reduced padding around `.wrap` class on smaller screens.
* Fixed issue with the page numbers not displaying the underline on `:hover`. This has been updated in the custom colors files, too.

* Rename customizer JS files to customize-preview.js and customize-controls.js to align with the core file naming and make it clearer where each file runs.
* Only show the colorscheme_hue control when there's a custom color scheme.
* Update preview JS handling for revised front page section handling, see below.
* Remove all references to "Theme Customizer" in code comments. It hasn't been called that since before 4.0.
* Clarify the purpose of the JS files by updated the code comments in the file headers.
* Improve code readability.
* Make the arbitrary number of front page sections filterable, for UI registration and output.
* Rename twentyseventeen_sanitize_layout to twentyseventeen_sanitize_page_layout to be clearer about what it sanitizes in case child themes or plugins consider reusing it.
* Rename page_options setting/control to page_layout as that's more reflective of what that option does; and again, helps for potential extensions.
* Make the page layout option contextual to pages and the sidebar being inactive, as the option only applies when there is no sidebar (per its description).
* Condense options into a single section.
* Add selective refresh for front page sections.
* Locate active_callback functions within customizer.php so that they're easier to find when editing customizer registrations, similarly to sanitize callbacks.
* Adjust the styling for placeholders for panels that aren't active.
* Ensure that the new visible edit shortcuts don't have any issues.

This adds the ability for themes to add support for videos in custom headers
by passing `'video' => true` as an argument when adding theme support for
custom headers.
Custom video headers are managed through the “Header Visuals” (i.e. “Header Image”)
panel in the Customizer where you can select a video from the media library or set a
URL to an external video (YouTube for now) for use in custom headers.
This introduces several new functions:
`has_header_video()` – Check whether a header video is set or not.
`get_header_video_url()` – Retrieve header video URL for custom header.
`the_header_video_url()` – Display header video URL.
`get_header_video_settings()` – Retrieve header video settings.
`has_custom_header()` – Check whether a custom header is set or not.
`get_custom_header_markup()` – Retrieve the markup for a custom header.
`the_custom_header_markup()` – Print the markup for a custom header.
And a new file, `wp-includes/js/wp-custom-header.js` that handles loading videos
in custom headers.
This also enables video headers in the Twenty Seventeen and Twenty Fourteen themes.

* Removes the left padding on the first cell in a row, and the right padding on the last cell in each row - the padding is still there between cells, so the contents don't meet.
* Does the opposite for RTL, and fixes some spacing issues.
* Updates the editor styles to match.

* Fixes the display issues with the header. The header doesn't look exactly like it does in newer browsers, but it's closer.
* Gets the font sizes a bit more consistent with how it looks like other browsers.
* IE8 doesn't support SVGs, so it's using the fallback styles for some of the icons. The fallbacks are limited to the absolutely necessary icons - so there is one for the submenu dropdown toggle icon, but not for the little 'hamburger' and X that sit in front of the 'menu' button.

Currently, it's hard to output an SVG in the comment function without a lot of extra effort. So this adds a simple border to the author avatar and removes previous code related to SVGs and/or Genericons.
