I re-worked the fstat patch.  Please comment on new version.  This fixes 
problem of fstat failing with -1 on pre-opened redirected device handles.
Example: stdin if prog < nul, stdout if prog > nul.
The old version had an ugly goto, unneeded call when dev_info was 
already in a variable, and actually missed some cases using
various SFT flags.  If we don't have trusted values at this point we will
fail below unless it's a device.
