In [49084] (for #50679), wp_get_attachment_metadata() was changed to improve performance, but it had the side effect of eliminating the ability to call it with no arguments and have it default to using the global $post.
This change restores that ability, while keeping the performance improvements from the original change.
Fixes#52196.

This enables, for example, the previous post status to be used by this hook without the need to first capture it on an earlier hook.
This also fixes the value of the `$fire_after_hooks` parameter in `get_default_post_to_edit()` so the `wp_after_insert_post` action correctly fires just once on the new post screen.

Instead of one cache entry for all upload folders for a site on multisite, this now caches for each folder and invalidates that cache based on context. In multisite, this should speed up `get_dirsize` calls since older directories that are much less likely to change will no longer have the size recalculated.

Using the canonical function name for PHP functions is strongly recommended, as aliases may be deprecated or removed without (much) warning.
This replaces all uses of the following:
* `join()` with `implode()`
* `sizeof()` with `count()`
* `is_writeable()` with `is_writable()`
* `doubleval()` with a `(float)` cast
In part, this is a follow-up to #47746.

When modifying terms assigned to an object, replace full term recounts with incrementing/decrementing the count as appropriate. This provides a significant performance boost on sites with a high number of term/object relationships and/or posts.
Introduces the functions `wp_increment_term_count()`, `wp_decrement_term_count()`, `wp_modify_term_count_by()` and `wp_modify_term_count_by_now()` for updating the term count.
Introduces the function `_wp_prevent_term_counting()` for preventing double counting on posts that are about to transition.
Adds the parameter `update_count_by_callback` to `register_taxonomy()` to allow developers to use a custom callback for incrementing or decrementing a term count.

This allows for edits to be made to a restored post before it goes live again. This also prevents scheduled posts being published unexpectedly if they are untrashed after their originally scheduled date.
The old behaviour of restoring untrashed posts to their original status can be reinstated using the `wp_untrash_post_set_previous_status()` helper function.
Also fixes an issue where the incorrect post ID gets passed to hooks if no post ID is passed to the function.

[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.
