qtest: Fix deadloop by running main loop AIO context's timers
qemu_clock_run_timers() only takes care of main_loop_tlg, we shouldn't
forget aio timer list groups.
Currently, the qemu_clock_deadline_ns_all (a few lines above) counts all
the timergroups of this clock type, including aio tlg, but we don't fire
them, so they are never cleared, which makes a dead loop.
For example, this function hangs when trying to drive throttled block

We find the nbd_recv_coroutines_enter_all function (triggered by a cancel
command or a network connection breaking down) will enter a coroutine which
is waiting for the sending lock. If the lock is still held by another coroutine,
the entering coroutine will be added into the co_queue again. Latter, when the
lock is released, a coroutine re-enter error will occur.
This bug can be fixed simply by delaying the setting of recv_coroutine as
suggested by paolo. After applying this patch, we have tested the cancel
operation in mirror phase looply for more than 5 hous and everything is fine.
Without this patch, a coroutine re-enter error will occur in 5 minutes.

qtest/ahci: Store hba_base in AHCIQState
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.

"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.

relies on pc architecture specific code in libqos. The next two patches will

The code in logic_imm_decode_wmask attempts to rotate a mask
value within the bottom 'e' bits of the value with
mask = (mask >> r) | (mask << (e - r));
This has two issues:
* if the element size is 64 then a rotate by zero results
in a shift left by 64, which is undefined behaviour
* if the element size is smaller than 64 then this will
leave junk in the value at bit 'e' and above, which is
not valid input to bitfield_replicate(). As it happens,
the bits at bit 'e' to '2e - r' are exactly the ones
which bitfield_replicate is going to copy in there,
so this isn't a "wrong code generated" bug, but it's
confusing and if we ever put an assert in

vfio: Use vfio type1 v2 IOMMU interface
The difference between v1 and v2 is fairly subtle, simply more
deterministic behavior for unmaps. The v1 interface allows the user
to attempt to unmap sub-regions of previous mappings, returning
success with zero size if unable to comply. This was a reflection of
the underlying IOMMU API. The v2 interface requires that the user
may only unmap fully contained mappings, ie. an unmap cannot intersect
or bisect a previous mapping, but may cover multiple mappings. QEMU
never made use of the sub-region v1 support anyway, so we can support
either v1 or v2. We'll favor v2 since it's newer.

vfio: unmap and free BAR data in instance_finalize
In the case of VFIO, the unrealize callback is too early to munmap the
BARs. The munmap must be delayed until memory accesses are complete.
To do this, split vfio_unmap_bars in two. The removal step, now called
vfio_unregister_bars, remains in vfio_exitfn. The reclamation step
is vfio_unmap_bars and is moved to the instance_finalize callback.
Similarly, quirk MemoryRegions have to be removed during
vfio_unregister_bars, but freeing the data structure must be delayed
to vfio_unmap_bars.

vfio: free dynamically-allocated data in instance_finalize
In order to enable out-of-BQL address space lookup, destruction of
devices needs to be split in two phases.
Unrealize is the first phase; once it complete no new accesses will
be started, but there may still be pending memory accesses can still
be completed.
The second part is freeing the device, which only happens once all memory
accesses are complete. At this point the reference count has dropped to
zero, an RCU grace period must have completed (because the RCU-protected
FlatViews hold a reference to the device via memory_region_ref). This is
when instance_finalize is called.
Freeing data belongs in an instance_finalize callback, because the
dynamically allocated memory can still be used after unrealize by the
pending memory accesses.
This starts the process by creating an instance_finalize callback and
freeing most of the dynamically-allocated data in instance_finalize.
Because instance_finalize is also called on error paths or also when
the device is actually not realized, the common code needs some changes
to be ready for this. The error path in vfio_initfn can be simplified too.

vfio: cleanup vfio_get_device error path, remove vfio_populate_device callback
Now that vfio_put_base_device is called unconditionally at instance_finalize
time, it can be called twice if vfio_populate_device fails. This works
but it is slightly harder to follow.
Change vfio_get_device to not touch the vbasedev struct until it will
definitely succeed, moving the vfio_populate_device call back to vfio-pci.
This way, vfio_put_base_device will only be called once.

address_space_destroy_dispatch is called from an RCU callback and hence

no new accesses can hit the destroyed AddressSpace so it is not necessary
to observe changes to the memory map. Move the memory_listener_unregister

I suspect this was screwed up when we stole the code from libxml2.
There the conditional reads
