- better support for non-blocking COMM and socket read/writes:
+ added necessary semantics to fd flags
+ no longer uses fd type (but fd flags) read/write semantic behavior
- fixed socket code to use the proper manifest constants
- fixes for kernel32.GetOverlappedResult without hEvent set
- in ntdll.Nt{Read|Write}File
+ always reset the event
+ added support for longlong offsets
+ better object disposal in error handling code paths
