As part of the initial checks to se ethat a writable disk really is 

writable, do the touch(1) dance with 512 bytes of information, rather
than just a single byte - the single byte read and write causes
problems on newer versions of FreeBSD, I am informed.  Patch from
Andrey Yakovlev, cleaned up to compile by myself.

Add support for Extended Inquiry Data VPD Page (0x86), reported to be
necessary to interoperate with the AIX initiator.

Add preliminary support for the Write and Verify SCSI operation (0x2e).
