* alter an existing table
* @param string $name name of the table that is intended to be changed.
* @param array $changes associative array that contains the details of each type
* of change that is intended to be performed. The types of
* changes that are currently supported are defined as follows:
* New name for the table.
* Associative array with the names of fields to be added as
* indexes of the array. The value of each entry of the array
* should be set to another associative array with the properties
* of the fields to be added. The properties of the fields should
* be the same as defined by the Metabase parser.
* Associative array with the names of fields to be removed as indexes
* of the array. Currently the values assigned to each entry are ignored.
* An empty array should be used for future compatibility.
* Associative array with the names of fields to be renamed as indexes
* of the array. The value of each entry of the array should be set to
* another associative array with the entry named name with the new
* field name and the entry named Declaration that is expected to contain
* the portion of the field declaration already in DBMS specific SQL code
* as it is used in the CREATE TABLE statement.
* Associative array with the names of the fields to be changed as indexes
* of the array. Keep in mind that if it is intended to change either the
* name of a field and any other properties, the change array entries
* should have the new names of the fields as array indexes.
* The value of each entry of the array should be set to another associative
* array with the properties of the fields to that are meant to be changed as
* array entries. These entries should be assigned to the new values of the
* respective properties. The properties of the fields should be the same
* as defined by the Metabase parser.
* 'file_limit' => array(),
* 'time_limit' => array()
* @param boolean $check indicates whether the function should just check if the DBMS driver
* can perform the requested table alterations if the value is true or
* actually perform them otherwise.
* @return mixed MDB2_OK on success, a MDB2 error on failure
