Subject: [PATCH] Twenty Seventeen: Fix incorrect `$content_width` value in
 theme

This addresses a major bug. Incorrectly setting the `$content_width` causes media embeds to end up with the wrong aspect ratio, among other issues. This fix uses `template_redirect`,  to ensure conditional theme tags can be used. It also defines a default value at `after_theme_setup` so that plugins have something to work with at `init`.

Props sstoqnov, laurelfulford, obenland.

Fixes #39272.
