2015-01-13 Version 4.0.1 Vincent Rogier vince.rogier@ocilib.net

    * C API
    
        - Fixed OCI_ObjectGetXXX() and OCI_ObjectSetXXX() : internal access to some field members could cause segfaults with complex object types having deep nested objects
        - Fixed possible segfaults in OCI_Execute() when string input binds are used in Unicode build on Unix platforms if the bind direction is not explicitly set
        - Added error type OCI_ERR_ARG_INVALID_VALUE
           - Input arguments handled as unsigned int value that correspond to a set of possible value are now checked. 
           - If the provided value does not fit within the set of expected values, an error is raised
        - Factorised some internal code using new methods OCI_ExternalSubTypeToSQLType() and OCI_ExternalSubTypeToSQLType()
        - Replaced some TAB occurrences with spaces
        - Internal code cleanup and refactoring
        - Internal minor code changes to remove GCC warnings with all possible paranoid options activated. 
        - Fixed internal macro OCI_CHECK_STMT_STATUS that had been wrongly modified in previous some refactoring

    * C++ API

        - Some Enum<> definitions where promoted to Flags<>
        - Fixed possible race condition in internal smart pointer members access in multithreaded applications
        - Fixed Statement::Bind<ostring>() : inadequate memory allocation parameter in BindAdaptor class constructor initialization
        - Fixed access violation in Pool object destructor when a global Pool object is not explicitly closed and destructor called after Environment::Cleanup()
        - Code refactoring and enhancements
        
    * Miscellaneous
    
        - Update Copyright to 2015
        - Fixed some typos in some files
