windows: add missing event functions
Add CreateEventEx, OpenEvent, ResetEvent and PulseEvent.
Also change eventAttrs to use the local definition of the
SecurityAttributes type, not the one from syscall.
GetConsoleScreenBufferInfo is also changed by re-running 'go generate'
to pass a pointer to ConsoleScreenBufferInfo (instead of a pointer to
pointer).
