Gary Pendergast e6904bc0e8 WPDB: When checking the encoding of strings against the database, make sure we're only relying on the return value of strings that were sent to the database. Also make sure that we're not trying to sanity check strings that've been marked as not needing sanity checking. 
Fixes #32279.

Gary Pendergast a6cb4b293c WPDB: `::strip_text_from_query()` doesn't pass a length to `::strip_invalid_text()`, which was causing queries to fail when they contained characters that needed to be sanity checked by MySQL.

Gary Pendergast 6759a210ca WPDB: Remove some of the complexities in `::strip_invalid_text()` associated with switching character sets between queries. Instead of trying to dynamically change connection character sets, we now rely on the value of `::charset`. This also fixes the case where queries were being blocked when `DB_CHARSET` was `utf8`, but the column character set was non-`utf8`. 
Fixes #32165.

Gary Pendergast f28b182a7c WPDB: When checking that text isn't too long to insert into a column, `LONGTEXT` columns could fail, as their length is longer than `PHP_INT_MAX`. Treating their length as a `float` instead of an `int` fixes this.

Gary Pendergast 4ee0da1798 WPDB: When extracting the table name from a query, we had a 1000 character limit on the SQL string that would be searched. This was a hangover from when the code was imported from HyperDB, and isn't appropriate for Core, where a wider range of queries are likely to be run.

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 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 f17d168a0f WPDB: Force `STRICT_ALL_TABLES` to be enabled as soon as we connect to the MySQL server. 
This improves data integrity when inserting and updating rows in the database, particularly when trying to insert emoji into posts stored with character sets that don't support emoji.

See #21212.

Gary Pendergast 739a20a659 WPDB: When a `db.php` drop-in is being used, and it doesn't explicitly define itself as connecting to MySQL, skip the character set checks. This ensures that existing drop-ins won't accidentally run checks that they don't support.

Gary Pendergast ecc27d0b27 When creating a post containing emoji, the post can be saved incorrectly if MySQL isn't using a character set that supports emoji. 
This change prevents the save from occurring, so it can be handled correctly in the UI.
