[34561] instituted the policy of forcing pagination for comments. This strategy
was intended to avert problems when 'page_comments' is set to 0 - as it is by
default - and the number of comments on a given post rises into the hundreds or
thousands. By forcing pagination in all cases, we ensured that WordPress would
not time out by processing unwieldy numbers of comments on a given pageload.
The strategy proves problematic, however, because comment permalinks are
generated using the page of the comment. Forcing pagination for posts that
were not previously paginated would change the URL of all comments that do not
appear on the default comment page.
This changeset reintroduces the 'page_comments' setting and its corresponding
checkbox on Settings > Discussion. A number of tests, which were written after
[34561], are modified to work now that 'page_comments' will, once again, be
disabled by default.

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.

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.

The existing invalid cron entries will not be purged automatically (as the 'timestamp' is never matched) so we do this ourselves.
Props mechter for noticing!

This change does the following things
* 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.
