LuaHook android native function, alse with base help lib for ue4
1、提供一些hook和常用内存读写函数到lua：
static const luaL_Reg XLUA[] =
{
{ "hook", lua_hook },
{ "unhook", lua_unhook },
{ "call", lua_call_function },
{ "argv", lua_set_argv },
{ "dlsym", lua_get_addr },
{ "dump", lua_dump },
{ "i2s", lua_i2s },
{ "s2i", lua_s2i },
{ "i2f", lua_i2f },
{ "f2i", lua_f2i },
{ "wint64", lua_write_int64 },
{ "rint64", lua_read_int64 },
{ "wdouble", lua_write_double },
{ "rdouble", lua_read_double },
{ "wint32", lua_write_int32 },
{ "rint32", lua_read_int32 },
{ "wfloat", lua_write_float },
{ "rfloat", lua_read_float },
{ "wint16", lua_write_int16 },
{ "rint16", lua_read_int16 },
{ "wint8", lua_write_int8 },
{ "rint8", lua_read_int8 },
{ "wstr", lua_write_string },
{ "rstr", lua_read_string },
{ "wwstr", lua_write_wstring },
{ "rwstr", lua_read_wstring },
{ "wslen", lua_get_wstring_len },
{ 0, 0 }
};
2、提供UE的对象属性解析功能，见ue.lua： read_fs(fs) write_fs(fs, str) enum_props(inst) ...
3、lua脚本md5校验，改变后即可重新加载，方便测试代码(lua的print已用LOGD替换)。
