Log:
[MSAFD]
- Print the caller in MsafdReturnWithErrno
- Initialize SockAsyncCompletionPort handle
- Check if the creation of the completion port failed
- Defer free of the socket information struct until the socket handle has been closed because the socket may have a pending select. When the socket is closed, the pending select is canceled, thus a apc routine is invoked which access the freed socket information struct.
- Fixes mIRC crash
- Should be merged to 0.3.13 branch
