Convert and run e107 using the MySQL/MariaDB utf8mb4 character set and
Browse files Browse the repository at this point in the history 
InnoDB storage engine

Components affected:
* `db_verify` now checks and corrects the table storage engine
* `db_verify` now checks and corrects the table default character set
  * Note: Field character sets can still be overridden
  * Note: When correcting, the entire table is converted to the target
    charset.
* The alt_auth plugin now connects via PDO using the e107 default
  charset, utf8mb4
* `e_db_pdo` now sets the charset to utf8mb4. This is currently not
  customizable because it was previously not customizable.
* `install.php` now generates an `e107_config.php` file with
  `$mySQLcharset = 'utf8mb4';`, though this option is not actually used.
* `install.php` now removes plugin tables before installing plugins.
* `e_db_mysql` now only accepts the `utf8mb4` charset. Previously, it
  only accepted the `utf8` charset.
* `e_db_mysql` now configures `mysqli_real_escape_string` to match the
  new default charset, `utf8mb4`.
* Plugin installations now use the preferred MySQL table storage engines
  and charsets.

The preferred MySQL table storage engines are now mapped like so:
* If `ENGINE=MyISAM` is specified, the actual storage engine set will be
  the first available of: InnoDB, Aria, Maria, MyISAM
* If `ENGINE=Aria` is specified, the actual storage engine set will be
  the first available of: Aria, Maria, MyISAM
* If `ENGINE=InnoDB` is specified, the actual storage engine set will be
  the first available of: InnoDB, XtraDB
* If `ENGINE=XtraDB` is specified, the actual storage engine set will be
  the first available of: XtraDB, InnoDB

The preferred MySQL character set is now aliased like so:
* `utf8`    => `utf8mb4`
* `utf8mb3` => `utf8mb3`
* `utf8mb4` => `utf8mb4`
