* @brief Updates rows

* Updates rows in the database. When $old_fields is set to an array,
* the system will only do an update if the fields in that array changed.
*
* Attention:
* Only the values in $old_fields are compared.
* This is an intentional behaviour.
*
* Example:
* We include the timestamp field in $fields but not in $old_fields.
* Then the row will only get the new timestamp when the other fields had changed.
*
* When $old_fields is set to a boolean value the system will do this compare itself.
* When $old_fields is set to "true" the system will do an insert if the row doesn't exists.
*
* Attention:
* Only set $old_fields to a boolean value when you are sure that you will update a single row.
* When you set $old_fields to "true" then $fields must contain all relevant fields!
*
* @param string $table Table name
* @param array $fields contains the fields that are updated
* @param array $condition condition array with the key values
* @param array|boolean $old_fields array with the old field values that are about to be replaced
