* Refactor the code related to struct processing. Fix Java bridge- test failure. Fixed test list: * bridgetest-javaserver * [CUT] smoketest * [JUT] forms_unoapi_1 * [JUT] forms_unoapi_2 * [JUT] forms_unoapi_3 * [JUT] forms_unoapi_4 * Clean higher bit to prevent compiler generate wrong code when pyuno calls functions through UNO environment. This fixes some weired uitest failure. * Reorder the datatype list. Optimize the inserting args section in uno2cpp.cxx. * Remove some unused code.
