[svn-r11762] Purpose: Adding more wrappers

Description:
    Added member function H5File::openFile and overloaded for convenience.
    Added overloaded getObjinfo to skip the middle parameter.
    Changed
        StrType(const size_t& size);
    to
        StrType(const int dummy, const size_t& size);
    because the first one clashed with
        StrType(const hid_t existing_id);

Platforms tested:
    Linux 2.4 (heping)
    SunOS 5.8 64-bit (sol)
    HPUX 11.00 (kelgia)
