f7465bfcf3 Comments: Further improve text of initial comment.
In [37888], the comment text was initially updated, however an opportunity to make the text less trivializing of actions that users will take was missed. To quote Helen Hou-Sandi: "It's important not to trivialize actions that are perfectly reasonable for a user to find tricky (where to go to log in is not exactly intuitive, even with the rewrites we have now)."

The text of the comment now reads:

> Hi, this is a comment.
> To get started with moderating, editing, and deleting comments, please visit the Comments screen in the dashboard.
> Commenter avatars come from <a href="https://gravatar.com">Gravatar</a>.

2f998cac7f Database: Normalize index definitions in dbDelta().
`dbDelta()` compares the index definitions against the result of `SHOW INDEX FROM $table_name`. This requires a specific format so indices are not unnecessarily re-created. This format wasn't ensured, until now.

* Parse the raw index definition to extract the type, name and columns so a normalized definition can be built (#20263, #34873).
* Standardize on uppercase types (#34871) and on 'KEY'. 'INDEX' is only a synonym for 'KEY'.
* Escape index names with backticks (#20263).
* Normalize columns: Ignore ASC and DESC definitions (#34959), remove whitespaces (#34869) and escape column names with backticks (#20263).
* Add backticks to all index change queries (#20263).

18ca26574b Database: dbDelta() will no longer try to downgrade the size of TEXT and BLOB columns.
When upgrading to `utf8mb4`, `TEXT` fields will be upgraded to `MEDIUMTEXT` (and likewise for all other `*TEXT` and `*BLOB` fields). This is to allow for the additional space requirements of `utf8mb4`.

On the subsequent upgrade, after the `utf8mb4` upgrade, `dbDelta()` would try and downgrade the fields to their original size again. At best, this it a waste of time, at worst, this could truncate any data larger than the original size. There's no harm in leaving them at their original size, so let's do that.

8b4a5d1ec0 Introduce metadata for taxonomy terms.
Adds a new table to the database schema (`wp_termmeta`), and a set of
`*_term_meta()` API functions. `get_terms()` and `wp_get_object_terms()`
now also support 'meta_query' parameters, with syntax identical to other
uses of `WP_Meta_Query`.

When fetching terms via `get_terms()` or `wp_get_object_terms()`, metadata for
matched terms is preloaded into the cache by default. Disable this behavior
by setting the new `$update_term_meta_cache` paramater to `false`.

To maximize performance, within `WP_Query` loops, the termmeta cache is *not*
primed by default. Instead, we use a lazy-loading technique: metadata for all
terms belonging to posts in the loop is loaded into the cache the first time
that `get_term_meta()` is called within the loop.

0d85038ce6 Schema: Increase the length of wp_options.option_name.
It's pretty easy to run over the `option_name` length, which causes undefined behaviour when inserting and retrieving options. Increasing the length from `VARCHAR(64)` to `VARCHAR(191)` significantly reduces the risk of this occurring.

Because `option_name` has a `UNIQUE` index, we can only increase it to 191 characters, rather than 255. The index can only use a prefix of 191 characters, so will incorrectly restrict long different strings that have the same prefix, if we make the column longer.

151d27369d Term splitting routine should be run in a separate process, triggered via wp-cron.
[32814] introduced a routine to split shared terms, which was run during the
regular WP database upgrade. This turned out to be problematic because plugins
are not loaded during the db upgrade (due to `WP_INSTALLING`), with the result
that plugins were not able to hook into the 'split_shared_term' action during
the bulk split. We work around this limitation by moving the term splitting
routine to a separate process, triggered by a wp-cron hook.

 * Allows utf8mb4 for the MySQL extension
 * Re-runs the utf8->utf8mb4 conversion for single sites, this will do nothing for tables already converted
 * Re-runs the utf8->utf8mb4 conversion for global tables in multisite when the environment supports utf8mb4
 * Removes upgrade_420() calling as upgrade_430() will perform those changes now instead

The index shortenings should have still taken place on utf8 sites previously, so there's no need to run those again.

ebb6aa1d4a Split upgrade_430() into two so that split_all_shared_terms() runs when upgrade_430_fix_comments() bails early.

Fix some egregious uses of tabbing.
Some functions can simply return `apply_filters(...)` instead of setting a variable that is immediately returned.
