[svn-r24925] Purpose: Fix HDFFV-7907

Description:
    Added transform property list functions
        // Constructor creates a dataset transform property list.
        DSetMemXferPropList(const char* expression);

        // Sets data transform expression.
        void setDataTransform(const char* expression) const;
        void setDataTransform(const H5std_string& expression) const;

        // Gets data transform expression.
        ssize_t getDataTransform(char* exp, size_t buf_size=0) const;
        H5std_string getDataTransform() const;

    Added test file tdspl.cpp.

Platforms tested:
    Linux/ppc64 (ostrich)
    Linux/32 2.6 (jam)
    SunOS 5.11 (emu)
