1a28ec87e1 Docs: Remove @access notations from method DocBlocks in wp-admin/* classes.
Prior to about 2013, many class methods lacked even access modifiers which made the `@access` notations that much more useful. Now that we've gotten to a point where the codebase is more mature from a maintenance perspective and we can finally remove these notations. Notable exceptions to this change include standalone functions notated as private as well as some classes still considered to represent "private" APIs.

See #41452.

eeefec932f Administration: Improve the usage of the button CSS classes.
Introduces some consistency in the usage of the button CSS classes, fixes the
focus style for accessibility and responsiveness of the buttons.

- Adds the `button` class to all primary buttons make them responsive
- Removes all `secondary-button` classes and replaces it with button when needed. `button-secondary` shouldn't be used and exists just for backward compatibility reasons
- Replaces classes inside `submit_button()` with a shorthand for some buttons, and use an empty string for the default `button` class. Passing `button` is unnecessary
- Adjusts `get_submit_button()` to remove empty items

d27606936b Allow custom bulk actions in admin list tables.
Bulk action filtering was introduced in 3.1, but only to remove default bulk actions, not add new ones.

Bulk actions can now be registered for all admin list table dropdowns via the `bulk_actions-{get_current_screen()->id}` filter. Handling custom bulk actions can be performed in the corresponding and newly introduced `handle_bulk_actions-${get_current_screen()->id}` filter.

7a24b60c2a List Tables: to ensure that get_primary_column_name() can match columns that were added via the "manage_{$screen->id}_columns" filer, call get_column_headers() instead of $this->get_columns().
List Table classes and `WP_Screen` are already tangled together. The parent list table constructor adds a filter that is called by a function that references the instance globally, even though we have access to it via composition directly in the class that is adding the filter. So the fact that functions here have to be called that reference a screen instance we already have access to is what one might call... less than elegant.

`WP_Posts_List_Table` calls `wp_edit_posts_query()` in `->prepare_items()` which is a wrapper for `wp()`. As such, we can obtain `orderby` and `order` via `get_query_var()`, instead of the URL.

For other list tables, it now shows a little notification bubble with the number of pending comments. The bubble and notification become plain text in the responsive list table view. It also shows no bubble when there are no comments at all, reducing some of the visual noise.

81c2f541b0 List tables: Add a fallback for the primary column.
Without a primary column defined, nothing shows in the responsive view at all, which is bad.

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.

b26accf35a List tables: Select All should not be a column header.
It sets a redundant relationship with all checkboxes in its column and also conveys wrong information for screen readers.

Why are people manually setting `$_column_headers` other than because somebody else told them to? Maybe time will tell.
