[PATCH v3 1/1] ntdll/unix: Add an option to inherit the Unix console handle.

[Aida Jonikienė]

From: Aida Jonikienė

I know this breaks Windows behavior but having apps print out
special debug messages to the terminal provides a good look
into the applications' development (for example I know that NFS
Underground has some "done" messages likely used for debugging).

I also don't want to keep another revert in my Wine tree just
for this one feature either so that's why I'm MR'ing this.

I considered adding a registry/winecfg entry for this behavior
but it would make this change much larger (and there's no good
place in winecfg to put this behavior in).

To enable this behavior, you can set WINEDEBUG=+unixcon variable
before launching an application.
