Gary Pendergast 722f25cd97 KSES: Allow the `download` attribute on `<a>` tags. 
To avoid this being a vector for bypassing the filetypes that are allowed to be uploaded, this attribute is only allowed to be added without a value.

Props kalpshit, arshidkv12, welcher, peterwilsoncc, marina_wp, pento.
See #44724.

Gary Pendergast 5d58c6dc66 KSES: Allow `url()` to be used in inline CSS. 
The cover image block uses the `url()` function in its inline CSS, to show the cover image. KSES didn't allow this, causing the block to not save correctly for Author and Contributor users. As KSES does already check each attribute name against an allowed list, we're able to add an extra check for certain attributes to be able to use the `url()` function, too.

Props peterwilsoncc, azaozz, pento, dd32.

Gary Pendergast 456f8015b7 KSES: Deprecate `wp_kses_js_entities()`. 
This function was originally introduced to fix an XSS attack in Netscape 4, which never affected any other browsers, or later versions of Netscape.

Aaron Jorbin dd983343d3 Formatting: Allow KSES custom elements with hyphens 
The W3C Custom Elements spec (http://www.w3.org/TR/custom-elements/#concepts) allows you to use your own custom DOM elements/tags. One of the main requirements is that the tag name "must contain a U+002D HYPHEN-MINUS character". This adjusts KSES to allow it.

Scott Taylor fc843ce4d0 There are some random `add_action()` and `add_filter()` calls littered around some files in `wp-includes/`. These should be moved to `wp-includes/default-filters.php` with the rest of the registered hooks. It seems like this was the best practice for awhile and then we randomly stopped. This file loads way before any of the includes, so the hooks will be registered for any request that loads WordPress, even `SHORTINIT` - a lot of the hooks registered won't run anyways (that's already the case).

Ryan Boren 43a7e695e9 Revert 23416, 23419, 23445 except for wp_reset_vars() changes. We are going a different direction with the slashing cleanup, so resetting to a clean slate. see #21767

Ryan Boren cc5ed3a485 Change all core API to expect unslashed rather than slashed arguments. 
The exceptions to this are update_post_meta() and add_post_meta() which are often used by plugins in POST handlers and will continue accepting slashed data for now.

Introduce wp_upate_post_meta() and wp_add_post_meta() as unslashed alternatives to update_post_meta() and add_post_meta(). These functions could become methods in WP_Post so don't use them too heavily yet.

Remove all escape() calls from wp_xmlrpc_server. Now that core expects unslashed data this is no longer needed.

Remove addslashes(), addslashes_gpc(), add_magic_quotes() calls on data being prepared for handoff to core functions that until now expected slashed data. Adding slashes in no longer necessary.

Introduce wp_unslash() and use to it remove slashes from GPCS data before using it in core API. Almost every instance of stripslashes() in core should now be wp_unslash(). In the future (a release or three) when GPCS is no longer slashed, wp_unslash() will stop stripping slashes and simply return what is passed. At this point wp_unslash() calls can be removed from core.

Introduce wp_slash() for slashing GPCS data. This will also turn into a noop once GPCS is no longer slashed. wp_slash() should almost never be used. It is mainly of use in unit tests.

Plugins should use wp_unslash() on data being passed to core API.

Plugins should no longer slash data being passed to core. So when you get_post() and then wp_insert_post() the post data from get_post() no longer needs addslashes(). Most plugins were not bothering with this. They will magically start doing the right thing. Unfortunately, those few souls who did it properly will now have to avoid calling addslashes() for 3.6 and newer.

Use wp_kses_post() and wp_kses_data(), which expect unslashed data, instead of wp_filter_post_kses() and wp_filter_kses(), which expect slashed data. Filters are no longer passed slashed data.

Remove many no longer necessary calls to $wpdb->escape() and esc_sql().

In wp_get_referer() and wp_get_original_referer(), return unslashed data.

Remove old stripslashes() calls from WP_Widget::update() handlers. These haven't been necessary since WP_Widget.

Switch several queries over to prepare().

Expect something to break.

Andrew Nacin 40543db45f Recommend the wp_kses_allowed_html filter over CUSTOM_TAGS. Soft deprecate CUSTOM_TAGS. see #17977, #20210.
