 Part I- Add FDO save point API interface methods

 This submission is the first part of RFC
 61(http://trac.osgeo.org/fdo/wiki/FDORfc61) implementation.

 This submission adds three interface methods in FdoITransaction interface.

 {{{
 class FdoITransaction : public FdoIDisposable
 {
     ......
     /// \brief
     ///  Create a save point in this transaction.
     ///
     /// \param suggestName
     /// Suggested save point name.
     ///
     /// \returns
     /// The actual name used by the provider
     FDO_API virtual FdoString* AddSavePoint(FdoString* suggestName) = 0;

     /// \brief
     ///  Release a specific save point.
     ///
     /// \param savePointName
     /// Save point name.
     ///
     /// \returns
     /// Returns nothing

     FDO_API virtual void ReleaseSavePoint(FdoString* savePointName) = 0;

     /// \brief
     ///  Rollback the transaction to a specified save point.
     ///
     /// \param savePointName
     /// Save point name.
     ///
     /// \returns
     /// Returns nothing
     FDO_API virtual void Rollback(FdoString* savePointName) = 0;
     ......
 }
 }}}

 Also a capability interface has to be added to support query for save
 point capabilities.


 {{{
 class FdoIConnectionCapabilities : public FdoIDisposable
 {
     ......
     /// \brief
     /// Returns whether the current connection supports save point.
     ///
     /// \return
     /// Returns true if the current connection supports save point, false
 otherwise.
     ///
     FDO_API virtual bool SupportsSavePoint() = 0;
     ......
 }
 }}}

 All providers have been updated with the above interface changes.
