std.Io: move fileWriteStreaming to Operation
...
This serves as an example to contributors of how to move VTable
functions to becoming an Operation, thereby enabling Batch API and
timeouts.

std.Io.Threaded: rework file reading to observe nonblocking flag
...
- batchAwaitAsync does blocking reads with NtReadFile (no APC, no event)
when the nonblocking flag is unset, but still takes advantage of
APCs when nonblocking flag is set.
- batchAwaitConcurrent returns error.ConcurrencyUnavailable when it
encounters a file_read_streaming operation on a file in blocking mode.
- fileReadStreaming avoids pointlessly checking sync cancelation status
when nonblocking flag is set, uses an APC with a done flag, and waits
on that value to change in NtDelayExecution before returning.
- fix incorrect use of NtCancelIoFile (ntdll function prototype was
wrong, leading to misuse)

std.Io.File: add non-blocking flag
...
On Windows, we need to know ahead of time whether a file was opened in
synchronous mode or asynchronous mode. There may be advantages to
tracking this state for POSIX operating systems as well.

std.Io.Threaded.batchWait better fix for any_done
...
It is legal to call batchWait with already completed operations in the
ring. In such case, we need to avoid waiting in the syscall. The
any_done flag was a poor way of tracking state we already have: whether
the completion queue is empty.
This problem affects the posix poll implementation as well.
Thanks again to jacobly for finding the problem.

std.Io.Threaded: fix bad use of AlertableSyscall

The defer would cause two problems:
1. keeping the state active during call to NtCancelIoFile
2. invalid state transition. after canceled is returned from
checkCancel, new status is already canceled. calling finish after
that is illegal.
