There is a function SetStdioPath to associate a standard stream
with a file or a device but what we really want is to use pipes as
standard streams. Despite that we implement pipes using a device,
we would have some limitations on the number of open pipes due to
the 3 character limit of device file name. Thus we don't take this
path. Another option would be to install a file system driver with
support for pipes; this would allow us to get rid of the device
name length limitation. However, with GnuPG we can get away be
redefining the standard streams and passing the handles to be used
on the command line. This has also the advantage that it makes
creating a process much easier and does not require the
SetStdioPath set and restore game. The caller needs to pass the
rendezvous ids using up to three options:
-&S0=<rvid> -&S1=<rvid> -&S2=<rvid>
They are all optional but they must be the first arguments on the
command line. Parsing stops as soon as an invalid option is found.
These rendezvous ids are then used to finish the pipe creation.*/
