For review... CD interfaces in wine

[eric pouech]

not ready yet for cvs inclusion (yet), this patch implements two things:
- it replaces the wine internal & proprietary cdrom interface (used 
in MCICDA and MSCDEX/int2F) with the proper win32 ioctl:s calls
- it allows opening any device with CreateFile (using the name "\.\E:")
(this is still very hackish, but not worse than what already existed)

patch posted for review/comments/enhancements... (before I go on
vacation, in case someone would work on something equivalent)

A+
