[CONDRV]

Initial commit of the ReactOS Console Driver.
For the moment, it's just able to load/unload, creating a "controller" device
and being able to DPRINT1 lots of messages when you try to access to it.

/*
* Remarks on the symbolic links :
*
* - \DosDevices\ is an alias to \??\
*
* - Using "\DosDevices\Global\<name>" allows the driver to ALWAYS
* create the symbolic link in the global object namespace. Indeed,
* under Windows NT-2000, the \DosDevices\ directory was always
* global, but starting with Windows XP, it became local to a session.
* One would then use \GLOBAL??\ to access to the global directory.
* However, this name doesn't exist under Windows NT-2000.
* Therefore, we use the trick to use the 'Global' symbolic link
* defined both under Windows NT-2000 and Windows XP and later,
* which exists in \DosDevices\, to access to \??\ (global) under
* Windows NT-2000, and to \GLOBAL??\ under Windows XP and later.
