Repace the running buffer pointer (scsi_buf) with a buffer offset
field (scsi_off). The later is alot easier to live-migrate.

Factor out packet completion to a separate function which
cares to get the MSDState->packet update right.

usb-storage can't handle requests in one go as the data transfer can be
splitted into lots of usb packets. Because of that there can be
normal in-flight requests at savevm time and we need to handle that.
With other scsi hba's this happens only in case i/o is stopped due to
errors and there are pending requests which need to be restarted
(req->retry = true).
So, first we need to save req->retry and then handle the req->retry =
false case. Write requests are handled fine already. For read requests
we have to save the buffer as we will not restart the request (and thus
not refill the buffer) on the target host.

The multifunction ich9 ehci controller with uhci companions uses a
different interrupt pin for each function. The three uhci devices
get pins A, B and C, whereas ehci uses pin D. This way the guest
can assign different IRQ lines to each controller.

Cancel transactions before saving vmstate is pretty pointless and just
causes disruptions. We need to cancel them before *loading* vmstate,
but in that case uhci_reset() handles it already and no special action
is needed.

Add a property for the uhci bandwidth. Can be used to make uhci
emulation run faster than real hardware.

Schedule bottom half on completion of async packets instead of calling
uhci_process_frame directly. This way we run uhci_process_frame only
once in case multiple packets finish in a row. Also check whenever
there is bandwidth left before scheduling uhci_process_frame.

uhci_process_frame() can be invoked multiple times per frame, so
accounting usb bandwith in a local variable doesn't fly, use a variable
in UHCIState instead. Also check the limit more frequently.

In commit 1bba0dc932 cpu_reset()
was renamed to cpu_state_reset(), to allow introducing a new cpu_reset()
that would operate on QOM objects.
All callers have been updated except for one in target-mips, so drop all
implementations except for the one in target-mips and move the
declaration there until MIPSCPU reset can be fully QOM'ified.
