[issue17723] Use FileRead and FileWrite in fileio.c on Windows

[John Ehresman]

New submission from John Ehresman:

File object's can use the win32 api FileRead and FileWrite instead of the CRT's read & write function.  This would eliminate the need to set the mode to binary on stdin & stdout, which is the underlying cause of issue 16587.  This could also possibly be the basis of adding nonblocking functionality.  An initial patch is attached, but I still need to verify what this does to the CRT mode of files that are opened by python (rather than already be opened, like stdin & stdout are).
