Provide back compat for allowed_themes option keys, which were from the early days of WordPress MU. see #20103. Curses.

Only update the old allowed_themes network option from the main site admin or in the network admin. see #20103, #20146.

The allowed_themes rolling upgrade for individual sites should not add empty allowedthemes arrays. If there are no allowed themes, don't add an empty option. Move the network rolling upgrade to upgrade_network(). see #20146.

In multisite, list broken themes on network/themes.php instead of on individual Manage Themes pages. see #20103.

In wp_get_themes() under multisite, filter out allowed themes before creating WP_Theme objects, rather than after. search_theme_directories() provides us the stylesheet of each theme which is all we need to do the proper intersection. This results in major performance gains on sites that have large numbers of themes unavailable to them. see #20103.

XMLRPC: Intoduce a date generation helper method to improve the dates returned over XMLRPC when we have a 0 date stored for drafts.

This improves the ability of clients to work with the new wp Post APIs. See #18429 and #19733 props maxcutler.

XMLRPC: Remove the "Backward Compatibility" code from the new api as we don't need to support this older format and it keeps the new api cleaner.

The new Posts API is designed so that you can fetch a post with get, update the data structure returned and submit that with edit and so we need to ensure to only include in get data in a single form - tags and categories are returned as terms.
See #18429
