Connect to a MySQL/MariaDB database using vibe.d's ConnectionPool (safe version).

This aliases MySQLPoolImpl!true as MySQLPool. Please see the mysql.impl.pool moddule for documentation on how to use MySQLPool.

This is the @safe version of mysql's pool module, and as such uses only @safe callback delegates. If you wish to use @system callbacks, import mysql.unsafe.pool.

See the Safe Migration document for more details.
