Embeds: Introduce embed templates into the template hierarchy via theme-compat.
Splits wp-includes/embed-template.php, introduced in 4.4, into five new templates that can be individually overridden by themes: * embed.php * embed-404.php * embed-content.php * header-embed.php * footer-embed.php Also introduces a new template tag for outputting the site title, `the_embed_site_title()`. The five new templates live in theme-compat, allowing for graceful fallbacks should themes prefer not to override any or all of them. Props swissspidy, imath, ocean90, DrewAPicture. See #34561. git-svn-id: https://develop.svn.wordpress.org/trunk@36693 602fd350-edb4-49c9-b593-d223f7449a82
