[linux-minidisc] using libusal for scsi access

[manner.moe@gmx.de]

Hello,
now i´ve tested scsi acces with libusal(included in cdrkit package) on 
windows.
windows port of libusal is limited to drives of type DRIVE_CDROM only so I 
had to make a small patch.

Instructions for building libusal.dll (MingW, MSYS and cmake must be 
installed) :
1. download latest cdrkit package from http://cdrkit.org/releases/
2. use patch for MinGW support as described here: http://lists.alioth.debian.org/pipermail/debburn-devel/2009-July/000647.html
    (download and install additional dependencies from MingW download site if 
needed)
3. use libusal_use_drive_removables.patch
4. use libusal_make_shared_lib.patch to make a dll with statically linked 
librols
5. type "cmake -G "MSYS Makefiles" in cdrkit root directory
6 change to cdrkit/include subdirectory and type "make"
7 change to cdrkit/librols subdirectory an type "make"
8 change to cdrkit/libusal subdirectory and type "make"
now we have libusal.dll and libusal.dll.a
To use it we need following headers from cdrkit/include:
 - complete usal directory
 - schily.h, standard.h and ccomdefs.h

Ask me for win32 binary of libusal if you don´t want to compile it yourself.

I´ve tested formatting a himd and it works fine.
The sample code is not complete yet, checking sense has to be added.
