command length, transfer size, and linear block address is handled.

Largely based on <scsi/scsi.h> from linux. Added into the tree so we
can use the defines everywhere, not just in scsi-generic.c (which is
linux-specific).

Changes:
* Move from open-coded lists to QTAILQ macros.
* Move the struct elements to the common data structures
(SCSIDevice + SCSIRequest).
* Drop free request pools.
* Fix request cleanup in the destroy callback.

Rename the SCSIRequest structs in scsi-disk.c and scsi-generic.c to
SCSIDiskReq and SCSIGenericReq. Create a SCSIRequest struct and move
the common elements over.

net_tap_init() always sets vnet_hdr using qemu_opt_get_bool(), but
initialize it in net_init_tap() just to reduce confusion.

Common state for all NICs.
The opaque member will replace the opaque member in VLANClientState
since only NICs need it.
The conf member will allow us to iterate over NICs, access the MAC
addr for the NIC and send a packet from each NIC in qemu_announce_self().
