Rachel Baker 56c18bb5af Users: Remove the “Name” column of the Users table from appearing sortable.
The “Name” column of the Users WP List Table is not sortable because this column displays a concatenation of two optional values, `first_name` and `last_name`. Even if WP_User_Query supported ordering queries in this manner, the resulting sequence would be chaotic.

Drew Jaynes b453c9e976 Users: Don't pass the current `WP_Users_List_Table` or `WP_MS_Users_List_Table` instance to the `users_list_table_query_args` filter after all.
After some discussion, it was decided that Multisite vs single site context can just as easily be derived using available functions like `is_network_admin()`, `get_current_screen()`, etc., rendering the second parameter moot. The hook was introduced in [34796].

Helen Hou-Sandí 8eb7f71e6b List tables: A better responsive view.
Instead of truncating columns, the data that's already in the markup can now be toggled into view. Only seems appropriate to celebrate four years of contributing by finally doing the first thing I ever mocked up.

Known issues / concerns:
* Custom list tables that don't define a primary column will show nothing at all. These are not extremely common, as `WP_List_Table` isn't really recommended for plugin consumption, but it happens. We need to come up with some kind of fallback.
* Some visual elements, particularly whitespace, could use refining.
* Needs a11y review.
* Touch performance on iOS feels sluggish - is there anything we can do about that?
* Would this be better accordion-style (only one expanded at a time)?
* Is `wp_strip_all_tags()` good enough for column titles that have HTML in them? It's essentially a workaround for the fact that core's comments column does that for the icon, which maybe it shouldn't. Perhaps worth another ticket, as a markup change would be fairly independent.
* Visual hierarchy is not great when expanded (also worthy of another ticket).
* Quick edit now becomes noticeably more annoying to cancel out of, as you have to scroll all the way down and you lose your position from before it was opened. Again, worthy of another ticket.

Scott Taylor fe6b5983df In PHP 5.0.0, `is_a()` became deprecated in favour of the `instanceof` operator. Calling `is_a()` would result in an `E_STRICT` warning.
In PHP 5.3.0, `is_a()` is no longer deprecated, and will therefore no longer throw `E_STRICT` warnings.

To avoid warnings in PHP < 5.3.0, convert all `is_a()` calls to `$var instanceof WP_Class` calls.

`instanceof` does not throw any error if the variable being tested is not an object, it simply returns `false`.

Note that this does not fix issues related to comment quick edit. Internal linking also continues to use the `.alternate` class for now. IE8 and below gracefully degrade by not having zebra striping.

Ryan Boren 5f809d1d22 Use wp_unslash() instead of stripslashes() and stripslashes_deep(). Use wp_slash() instead of add_magic_quotes().

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 d88922565e Less insane multiple role handling in the users list table.
If the user has more than one role, opt to show the first role that is
'editable', if present. Otherwise, fall back to the remaining roles.

In the future, we should show a comma-separated list of all roles,
editable or otherwise, and this list should be filterable, either by user,
or by the roles which can appear. Probably both.

In multisite, only hide users that have no capabilities (in case they
possess a leftover, empty wp_xx_capabilities key from the MU days),
not users that have no role, as they may have a cap but no role.

see #22361. fixes #17860.
