MySQL Compatibility Issues: mysqldump

I ran into multiple MySQL compatibility issues when attempting to parse a dump produced by `sudo mysqldump dbname > dbname_backup.sql` (also see [mysqldump docs](https://dev.mysql.com/doc/refman/8.0/en/mysqldump.html) or [mariadb docs](https://mariadb.com/kb/en/mysqldump/)).

Here is an example of `mysqldump` generated SQL (this database is from a [WordPress](https://wordpress.com/) installation):
```
-- MySQL dump 10.16 Distrib 10.1.26-MariaDB, for debian-linux-gnu (x86_64)

--
-- Table structure for table `wp_users`
--

DROP TABLE IF EXISTS `wp_users`;
/*!40101 SET @saved_cs_client = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `wp_users` (
`ID` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
`user_login` varchar(60) COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT '',
`user_pass` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT '',
`user_nicename` varchar(50) COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT '',
`user_email` varchar(100) COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT '',
`user_url` varchar(100) COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT '',
`user_registered` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
`user_activation_key` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT '',
`user_status` int(11) NOT NULL DEFAULT '0',
`display_name` varchar(250) COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT '',
PRIMARY KEY (`ID`),
KEY `user_login_key` (`user_login`),
KEY `user_nicename` (`user_nicename`),
KEY `user_email` (`user_email`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
/*!40101 SET character_set_client = @saved_cs_client */;

--
-- Dumping data for table `wp_users`
--

LOCK TABLES `wp_users` WRITE;
/*!40000 ALTER TABLE `wp_users` DISABLE KEYS */;
INSERT INTO `wp_users` VALUES (1,'MyUser','PasswordHash','myuser','myuser@example.com','','2020-09-22 14:45:28','',0,'My\'User');
/*!40000 ALTER TABLE `wp_users` ENABLE KEYS */;
UNLOCK TABLES;
```

More specifically (deleting various bits to expose more errors):
- https://github.com/ballista-compute/sqlparser-rs/issues/279
- `sql parser error: Expected end of statement, found: ENGINE`
- `sql parser error: Expected an SQL statement, found: LOCK`
- `sql parser error: Expected ), found: User`
(see `'My\'User'` in the example - it seems like the escaping on the `'` immediately before `User` was not handled)
- `sql parser error: Expected an SQL statement, found: UNLOCK`

Commencez par reproduire les erreurs de l'analyseur avec le SQL mysqldump présenté dans l'issue, notamment ENGINE, LOCK TABLES, les apostrophes échappées et UNLOCK. Comparez chaque construction avec la syntaxe MySQL ou MariaDB prise en charge par l'analyseur ; le travail est terminé lorsque les instructions de dump indiquées sont analysées avec succès, sans régression.
