Options

added config parameter Group on connection 

    moved NdbWaiter, m_ndb_cluster_connection, to impl class
    moved node selection things to cluster connection
    moved all private things to impl class
    added opts for shared memory and node selection
    changed opts handling somewhat; introduced enum for options and common handling of option variables
    added checks for transporter support
    automatic addition of shared mem transporters
    moved wait_until_ready code to cluster connection
    added control of usage of new node selection method

* This method is a modification of Ndb::startTransaction,
* in which we use only the first two chars of keyData to
* select transaction coordinator.
* This is referred to as a distribution group.
* There are two ways to use the method:
* - In the first, the two characters are used directly as
* the distribution key, and
* - in the second the distribution is calculated as:
* (10 * (char[0] - 0x30) + (char[1] - 0x30)).
* Thus, in the second way, the two ASCII digits '78'
* will provide the distribution key = 78.
*
* @note Transaction priorities are not yet supported.
*
* @param aPrio Priority of the transaction.<br>
* Priority 0 is the highest priority and is used for short transactions
* with requirements on low delay.<br>
* Priority 1 is a medium priority for short transactions.<br>
* Priority 2 is a medium priority for long transactions.<br>
* Priority 3 is a low priority for long transactions.
* @param keyData is a string of which the two first characters
* is used to compute which fragement the data is stored in.
* @param type is the type of distribution group.<br>
* 0 means direct usage of the two characters, and<br>
* 1 means the ASCII digit variant.
* @return NdbConnection, or NULL if it failed.
