Commit 9ef2e93f introduced the concept of tagging ATAPI commands as
NONDATA, but this introduced a regression for certain commands better
described as CONDDATA. read_cd is such a command that both requires
a non-zero BCL if a transfer size is set, but is perfectly content to
accept a zero BCL if the transfer size is 0.
This test adds a regression test for the case where BCL and nb_sectors
are both 0.
Flesh out the CDROM tests by:
(1) Allowing the test to specify a BCL
(2) Allowing the buffer comparison test to compare a 0-size buffer
(3) Fix the BCL specification in libqos (It is LE, not BE)
(4) Add a nice human-readable message for future SCSI command additions

In a couple of places ahci-test makes assumptions about how the tokens
returned from qpci_iomap() are formatted in ways it probably shouldn't.
First in verify_state() it uses a non-NULL token to indicate that the AHCI
device has been enabled (part of enabling is to iomap()). This changes it
to use an explicit 'enabled' flag instead.
Second, it uses the fact that the token contains a PCI address, stored when
the BAR is mapped during initialization to check that the BAR has the same
value after a migration. This changes it to explicitly read the BAR
register before and after the migration and compare.
Together, these changes will make the test more robust against changes to
the internals of the libqos PCI layer.

As part of streamlining the AHCI tests interface, it'd be nice
if specying a size of zero could be handled without special branches
and the allocator could handle this special case gracefully.
This lets me use the "ahci_io" macros for non-data commands, too,
which moves me forward towards shepherding all AHCI qtests into

* The migration is performed in such a way that it does not assume

you can use each QOSState object completely independently and then at
an arbitrary point decide to migrate, and the destination object will
now be consistent with the memory within the source guest. The source

after a read, the guest data will be in a host buffer, and for a write,
the data will be transmitted to guest memory prior to the block operation.
