When `wp_count_posts()` is cached, it does so with all statuses defaulted to 0. The problem is however, if this is called before all plugins have registered their desired statuses, they won't have that default.
Fixes#49685.

* Move default term assignment from `wp_set_object_terms()` to `wp_insert_post()`.
* Make sure the passed taxonomy list overwrites the existing list if not empty.
* Remove the default term option on `unregister_taxonomy()`.
* Prevent deletion of the default term in `wp_delete_term()`.

The new default_term argument is added to `register_taxonomy()` allowing a user to define the default term `name` and optionally `slug` and `description`.

This allows for hooking into both the create and update events with a single callback, in the same way that is already possible for posts via the `save_post` and `save_post_{$post->post_type}` actions.

This further makes the function more consistent with `get_the_ID()` or `wp_get_post_parent_id()`, both returning `false` for a non-existing post.
Additionally, document that `get_post_thumbnail_id()` returns `0` if the thumbnail image is not set.
Follow-up to [47160].

The filter is the callback function added with `add_filter()`, therefore the hook passes a value to the filter, and the filter returns a value to change its behaviour.
The documentation is referring to the latter.

This solution extends the wp_insert_post_data filter to pass in addition to the slashed/sanitized/processed data, and the slashed/sanitized/unprocessed data, to also pass the initial slashed/unsanitized/unprocessed data which was passed into wp_insert_post(). This then allows plugins to have complete control over how sanitization is performed based on the post type.

This ensures that `wp_update_post()` does not unintentionally modify post tags if the post has several tags with the same name but different slugs.
Tags should only be modified if `tags_input` parameter was explicitly provided, and is different from the existing tags.

[3525] allowed a difference up to 59 seconds between the post date/time and the current time to consider the post published instead of scheduled, but that didn't take start of a new minute into account.
Rapidly creating post fixtures in unit tests could encounter a one-second discrepancy between `current_time( 'mysql' )` and `gmdate( 'Y-m-d H:i:s' )`, returning values like `2019-12-16 23:43:00` vs. `2019-12-16 23:42:59`, respectively, and setting the post to a `future` status instead of `publish`.
[45851], while working as intended, made the issue somewhat more likely to occur.
This caused all sorts of occasional random failures in various tests on Travis, mostly on PHP 7.1.
