Remove "growable" option from the "open" command and from the qemu-io
command line. qemu-io is about to be converted to BlockBackend which
will make sure that no request exceeds the image size, so the only way
to keep "growable" would be to use BlockBackend if it is not given and
to directly access the BDS if it is.
qemu-io is a debugging tool, therefore removing a rarely used option
will have only a very small impact, if any. There was only one
qemu-iotest which used the option; since it is not critical, this patch
just removes it.

This case utilizes qemu-io command "aio_{read,write} -q" to verify the
effectiveness of IO throttling options.
It's implemented by driving the vm timer from qtest protocol, so the
throttling timers are signaled with determinied time duration. Then we
verify the completed IO requests are within 10% error of bps and iops
limits.
"null" protocol is used as the disk backend so that no actual disk IO is
performed on host, this will make the blockstats much more
deterministic. Both "null-aio" and "null-co" are covered, which is also
a simple cross validation test for the driver code.

ahci_io is a wrapper around ahci_guest_io that takes a pointer to host
memory instead, and will create a guest memory buffer and copy the data
to/from as needed and as appropriate for a read/write command, such that
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.

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.

These macros were a bad idea: They relied upon certain arguments being
present locally with a specific name.
With the endgoal being to factor out AHCI helper functions outside of
the test file itself, these have to be replaced by more explicit helper
setter/getter functions.

Introduce a set of "static inline" register helpers that are intended to
replace the current set of macros with more functional versions that are
better suited to inclusion in libqos than porcelain macros.
As a stopgap measure before eliminating the porcelain macros, define them
to use the new functions defined in the ahci.h header.

Rely on the PCI Device's bus pointer instead.
One less global to worry about.

Move barsize, ahci_fingerprint and capabilities registers into
the AHCIQState object, removing global ahci-related state
from the ahci-test.c file.
More churn, less globals.

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.

Create an operations structure so that the libqos interface can be
architecture agnostic, and create a pc-specific interface to functions
like qtest_boot.
Move the libqos object in the Makefile from being ahci-test only to
being linked with all tests that utilize the libqos features.

To avoid the architecture-specific implementations of the generic qtest
allocator having to know about fields within the allocator, add a
page_size setter method for users or arch specializations to use.
The allocator will assume a default page_size for general use, but it
can always be overridden.
Since this was the last instance of code directly using properties of the
QGuestAllocator object directly, modify the type to be opaque and move
the structure inside of malloc.c.
mlist_new, which was previously exported, is made static local to malloc.c,
as it has no external users.
[Peter Maydell <peter.maydell@linaro.org> reported the following clang
warning:
tests/libqos/malloc.c:35:3: warning:
