Gary Pendergast a2693fd860 Database: Restore numbered placeholders in `wpdb::prepare()`. 
[41496] removed support for numbered placeholders in queries send through `wpdb::prepare()`, which, despite being undocumented, were quite commonly used.

This change restores support for numbered placeholders (as well as a subset of placeholder formatting), while also adding extra checks to ensure the correct number of arguments are being passed to `wpdb::prepare()`, given the number of placeholders.

See #41925.

Gary Pendergast fd247bc2e4 Database: When parsing the host, leave the port and socket as `null` if they're not defined. 
This fixes a change in behaviour introduced by [41629].

The host is set to an empty string when it isn't defined, this continues existing behaviour. In particular, the mysqli library treats a `null` host as being the same as `localhost`, which is not always the intended behaviour.

Gary Pendergast f0492c5da8 Database: Fix some PHP errors introduced in [41662]. 
PHP < 5.4 requires a `$matches` parameter to be passed to `preg_match_all()`

`wpdb::prepare()` can be called before translations are loaded, so needs appropriate `wp_load_translations_early()` calls.

Drew Jaynes 0860bb2771 Docs: Remove `@access` notations from method DocBlocks in wp-includes/* 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.

Gary Pendergast 2dee7cdffc Database: Fall back to `utf8` when `utf8mb4` isn't supported. 
Sometimes, `DB_CHARSET` will be set to `utf8mb4`, even if the current setup doesn't support `utf8mb4`. After [38442], this can cause significant character set failures, causing the connection to fall back to `latin1`.

Instead of doing this, we now check that the connection supports `utf8mb4` before trying to use it, and fall back to `utf8` when we need to.

Gary Pendergast dd9aaba852 Database: Don't force an unsupported character set that previously would've silently failed. 
[37320] corrected some behaviour in how PHP and MySQL character sets are matched up. This was correct, but had the side effect of causing some incorrectly configured sites to start failing.

Prior to [37320], if `DB_CHARSET` was set to `utf8mb4`, but the PHP version didn't support `utf8mb4`, it would fall back to the default character set - usually `latin1`. After [37320], the `SET NAMES` query would force MySQL to treat the connection character set as `utf8mb4`, even if PHP wasn't able to understand it.

By checking if `mysqli_set_charset()` succeeded, we can simulate the old behaviour, while maintaining the fix in [37320].

Gary Pendergast 69147eb345 Database: Split the logic of `wpdb::init_charset()` into a separate method. 
The logic for determining the appropriate character set and collation to use is becoming more complex, particularly with the recent additions of [37522] and [37523]. As `init_charset()` has side effects, and makes use of constants instead of parameters, it's not possible to unit test this logic.

This commit splits the logic part of `init_charset()` out into a new method, `wpdb::determine_charset()`, along with appropriate unit tests.

The locale-specific collations do have extra collation rules just for that language, so it's useful to maintain compatibility.

Boone Gorges 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.

Dion Hulse cbacb92dae Enable utf8mb4 for MySQL extension users. Previously utf8mb4 was limited to MySQLi users only unintentionally. 
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.

Gary Pendergast 6a9d744b42 WPDB: When we check the character set of a column, and find that it's `utf8mb4`, we should also check that the current connection supports `utf8mb4`. It's possible that the environment may have changed since upgrading the DB, so we can fall back to `utf8` when that happens. 
Fixes #31771.

Gary Pendergast 2a8a5c963a WPDB: When we're checking to see if the MySQL client library supports `utf8mb4`, we need a separate check for `mysqlnd` versions, which using different version numbering to `libmysqlclient`. 
Props MattyRob.

Gary Pendergast 8c7ffba3b2 WPDB: HHVM doesn't support passing a DB link to `mysqli_get_client_version()`. While we usually pass a DB link to every `ext/mysql` and `mysqli` function call, we don't really need to do that here, as there's no way for the client library to change mid page load. 
Another fun fact is that `mysql_get_client_version()` doesn't exist, but `mysql_get_client_info()` (along with `mysqli_get_client_info()') do. So, we're switching to them, in order to add a pleasing symmetry to the client version check.

Gary Pendergast b2cf823105 WPDB: If a site is using the `utf8` charset, and their version of MySQL supports `utf8mb4`, auto-upgrade them to `utf8mb4`. 
This patch also resizes some indexes, to allow for the 767 byte index size limit in standard MySQL installs.

Scott Taylor 60b0cd7943 The keyword `elseif` should be used instead of `else if` so that all control keywords look like single words.
