- use platform independent data types in debug-engine library - add os_socket APIs and provide windows and posix implementation - avoid using platform related header files in non-platform layer - use format specifiers macros for sprintf and sscanf - change thread handle type from uint64 to korp_tid - add lock when sending socket packet to avoid thread racing
