[svn-r26643] Purpose: Adding new wrappers (HDFFR-9167 partially)

Description:
    Added wrappers for C functions H5P[s/g]et_libver_bounds and wrappers
    for getting object header version

      // Sets bounds on versions of library format to be used when creating
      // or writing objects.
      void setLibverBounds(H5F_libver_t libver_low, H5F_libver_t libver_high) const;

      // Gets the current settings for the library version format bounds.
      void getLibverBounds(H5F_libver_t& libver_low, H5F_libver_t& libver_high) const;

      // Returns the object header version of an object in a file or group,
      // given the object's name.
      unsigned childObjVersion(const char* objname) const;
      unsigned childObjVersion(const H5std_string& objname) const;

Platforms tested:
    Linux/64 (platypus)
    Linux/32 2.6
    SunOS 5.11
