Setting booktype on BTC 100[48] drives

[Dave Huang <khym@azeotrope.org>]

Does anyone have a patch to allow dvd+rw-booktype to set the booktype
on the BTC 1004/1008, or want to write one?

I believe the magic incantation CDBs are:

Set DVD+/-RW media to DVD-ROM: fa 00 01 00 00 00 00 00 00 00 aa ff
Set DVD+RW media to DVD+RW:    fa 00 92 00 00 00 00 00 00 00 aa ff
Set DVD-RW media to DVD-RW:    fa 00 32 00 00 00 00 00 00 00 aa ff
Set DVD+/-R media to DVD-ROM:  fa 00 00 01 00 00 00 00 00 00 aa ff
Set DVD+R media to DVD+R:      fa 00 00 a0 01 00 00 00 00 00 aa ff
Set DVD-R media to DVD-R:      fa 00 00 20 01 00 00 00 00 00 aa ff
"Clear" (whatever that means): fa 00 00 00 01 00 00 00 00 00 aa ff

You may also have to send 0x14 zero bytes as data, but I don't know if
that's actually required.

And I don't know how to tell if the drive is a BTC or not, other than
the INQUIRY data, which for my drive is:

05 80 00 32 1f 00 00 00 44 56 44 52 57 20 20 20  ...2....DVDRW

30 33 35 37                                      0357
