This patch adds the AHCICommand structure, and a set of functions to
operate on the structure.
ahci_command_create - Initialize and create a new AHCICommand in memory
ahci_command_free - Destroy this object.
ahci_command_set_buffer - Set where the guest memory DMA buffer is.
ahci_command_commit - Write this command to the AHCI HBA.
ahci_command_issue - Issue the committed command synchronously.
ahci_command_issue_async - Issue the committed command asynchronously.
ahci_command_wait - Wait for an asynchronous command to finish.
ahci_command_slot - Get the number of the command slot we committed to.
Helpers:
size_to_prdtl - Calculate the required minimum PRDTL size from
a buffer size.
ahci_command_find - Given an ATA command mnemonic, look it up in the
properties table to obtain info about the command.
command_header_init - Initialize the command header with sane values.
command_table_init - Initialize the command table with sane values.

This patch adds a few helpers to help sanity-check the response of the
AHCI device after a command.
ahci_d2h_check_sanity inspects the D2H Register FIS,
ahci_pio_check_sanity inspects the PIO Setup FIS, and
ahci_cmd_check_sanity inspects the command header.
To support the PIO sanity check, a new structure is added for the
PIO Setup FIS type. Existing FIS types (H2D and D2H) have had their
members renamed slightly to condense reserved members into fewer
fields; and LBA fields are now represented by arrays of 8 byte chunks
instead of independent variables.

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
header, respectively.
ahci_cmd_pick chooses the first available but least recently used
command slot to allow us to cycle through the available command slots.
ahci_command_destroy obliterates all information contained within a
given slot's command header, and frees its associated command table,
but not its DMA buffer!
Lastly, the command table pointer fields (dba and dbau) are merged into
a single 64bit value to make managing 64bit tests simpler.

which is not true for a number of cases:
- emulating targets with a different endianness than the host
- bi-endian targets, where the correct endianness depends on the virtio

- upcoming support for the virtio-1 standard mandates little-endian
accesses even for big-endian targets and hosts
Make sure to use accessors that depend on the virtio device.

Store the HBA memory base address in the new state object, to simplify
function prototypes and encourage a more functional testing style.
This causes a lot of churn, but this patch is as "simplified" as I could
get it to be. This patch is therefore fairly mechanical and straightforward:
Any case where we pass "hba_base" has been consolidated into the AHCIQState
object and we pass the one unified parameter.
Any case where we reference "ahci" and "hba_state" have been modified to use
"ahci->dev" for the PCIDevice and "ahci->hba_state" to get at the base memory
address, accordingly.
Notes:
- A needless return is removed from start_ahci_device.
- For ease of reviewing, this patch can be reproduced (mostly) by:
# Replace (ahci, hba_base) prototypes with unified parameter
's/(QPCIDevice \*ahci, void \*\?\*hba_base/(AHCIQState *ahci/'
# Replace (ahci->dev, hba_base) calls with unified parameter
's/(ahci->dev, &\?hba_base)/(ahci)/'
# Replace calls to PCI config space using "ahci" with "ahci->dev"
's/qpci_config_\(read\|write\)\(.\)(ahci,/qpci_config_\1\2(ahci->dev,/'
After these, the remaining differences are easy to review by hand.

The intent of this file is to serve as a misc. utilities file to be
shared amongst tests that are utilizing libqos facilities.
In a later patch, migration test helpers will be added to libqos.c that
will allow simplified testing of migration cases where libqos is
"Just Enough OS" for migrations testing.
The addition of the AHCIQState structure will also allow us to eliminate
global variables inside of qtests to manage allocators and test instances
in a better, more functional way.
libqos.c:
- Add qtest_boot
- Add qtest_shutdown
libqos.h:
- Create QOSState structure for allocator and QTestState.
ahci-test.c:
- Move qtest_boot and qtest_shutdown to libqos.c/h
- Create AHCIQState to interface with new qtest_boot/shutdown prototypes
- Modify tests slightly to use new types.
For now, the new object file is only linked to ahci-test, because it still
relies on pc architecture specific code in libqos. The next two patches will
