Theme Customizer: First pass for upload controls, using background image as an example. Add a wrapper for Plupload that allows for custom upload UIs. see #19910.

wp.Uploader is a wrapper that provides a simple way to upload an attachment (using the wp_ajax_upload_attachment handler). It is intentionally decoupled from the UI. When an upload succeeds, it will receive the attachment information (id, url, meta, etc) as a JSON response. If the upload fails, the wrapper handles both WordPress and plupload errors through a single handler.

As todos, we should add drag classes for the uploader dropzone and account for the rough 100mb filesize limit in most browsers. The UI for the customizer upload controls could be improved as well.

Updates to WP_Theme, wp_get_themes(), and related deprecated functions, after [UT570] [UT578] [UT579]. see #20103.
 * ['Template Files'] and ['Stylesheet Files'] need to return files from the parent theme as well.
 * Don't strip links from the Author header. Some themes rely on the previous behavior, such as to link multiple authors (Sandbox, for example.) Don't restore links to the Name, that's just a bad idea.
 * Ensure we are always passing around arrays in get_files/scandir.
 * Better inline doc for wp_get_themes() arguments.
 * Introduce a 'force' flag for search_theme_directories() to re-scan, rather than return the cache. We will use this to re-build the theme_roots transient in get_theme_roots(), but it is more helpful for unit tests. Since search_theme_directories() is cached, don't cache again in wp_get_themes(). (Again benefits testing.)
 * Handle duplicate theme names in the old get_themes() when two themes match (and neither are a default theme, which is already handled). wp_get_themes() will consider both names to be the same; this is just for back compat since get_themes() is keyed by name.
 * Include an old array key in wp_broken_themes().
