Adds command header helper functions:
-ahci_command_header_set
-ahci_command_header_get,
-ahci_command_destroy, and
-ahci_cmd_pick
These helpers help to quickly manage the command header information in
the AHCI device.
ahci_command_header_set and get will store or retrieve an AHCI command
Add a routine that can be used to engage the AHCI
device at a not-granular level so that bringing up
the functionality of the HBA is easy in future tests
that are not concerned with testing the bring-up process.

Adds a test case for AHCI wherein we write a 4K
block of a changing pattern to sector 0, then
read back that 4K and compare the transmit and
receive buffers.

A minor sanity check to assert that the sector size is 512.
The current block layer code deeply assumes that the IDE
sector size will be 512 bytes, so we carry forward that assumption
here.
This is useful for the DMA tests, which currently assume that
a sector will always be 512 bytes.

An follow up questions.
Suppose I have a running VM with two virtual disks, I would like to migrate
the vm from host A to host B. Both host A and host B have their own
isolated storage devices. Is there anyway to migrate the vm's memory, two
virtual disk images and other states together from host
Commit d8d95814609e replaced a number of memory_region_destroy()
calls with object_unparent() calls. The logic appears to be that
subregions need to be unparented, but the base region is destroyed
with the device object. Doing hotplug testing with vfio-pci I
occasionally get a segfault from

Coverity spot:
Function xen_pt_bar_offset_to_index() may returns a negative
number (-1) value index, which as an index to array d-io_regions.
Let's directly and simply pass index as an argument to
xen_pt_bar_reg_parse().

The array length of s-real_device.io_regions[] is
PCI_NUM_REGIONS - 1. Add a check, just make Coverity happy.
