Anthony Liguori 39bffca203 qdev: register all types natively through QEMU Object Model
This was done in a mostly automated fashion.  I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.

The first step was a sed-based addition of the parent type to the subclass
registration functions.

The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.

Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.

We are almost fully converted to QOM after this commit.

The current code that updates the cbp value after a transfer looks like this:
td.cbp += ret;
if ((td.cbp & 0xfff) + ret > 0xfff) {

because the 'ret' value is effectively added twice the check may fire too early
when the overflow hasn't happened yet.

Honour the maximum packet size for endpoints; this applies when

Gerd Hoffmann e0b8e72dd9 usb: fix port reset
commit 891fb2cd45 removed the implicit
detach before (re-)attaching in usb_attach().  Some usb host controllers
used that behavior though to do a port reset by a detach+attach
sequence.

This patch establishes old behavior by adding a new usb_reset() function
for port resets and putting it into use, thereby also unifying port
reset behavior of all host controllers.  The patch also adds asserts to
usb_attach() and usb_detach() to make sure the calls are symmetrical.

Gerd Hoffmann 891fb2cd45 usb: claim port at device initialization time.
This patch makes qemu assign a port when creating the device, not when
attaching it.  For most usb devices this isn't a noticable difference
because they are in attached state all the time.

The change affects usb-host devices which live in detached state while
the real device is unplugged from the host.  They have a fixed port
assigned all the time now instead of getting grabbing one on attach and
releasing it at detach, i.e. they stop floating around at the usb bus.

The change also allows to simplify usb-hub.  It doesn't need the
handle_attach() callback any more to configure the downstream ports.
This can be done at device initialitation time now.  The changed
initialization order (first grab upstream port, then register downstream
ports) also fixes some icky corner cases.  For example it is not possible
any more to plug the hub into one of its own downstream ports.

The usb host adapters must care too.  USBPort->dev being non-NULL
doesn't imply any more the device is in attached state.  The host
adapters must additionally check the USBPort->dev->attached flag.

Zap data pointer from USBPacket, add a QEMUIOVector instead.
Add a bunch of helper functions to manage USBPacket data.
Switch over users to the new interface.

Note that USBPacket->len was used for two purposes:  First to

transfered bytes or the status code on async transfers.  There
is a new result variable for the latter.  A new status code
was added to catch uninitialized result.

Nobody creates iovecs with more than one element (yet).
Some users are (temporarely) limited to iovecs with a single
element to keep the patch size as small as possible.

Hans de Goede 4706ab6cc0 usb: Replace device_destroy bus op with a child_detach port op
Note this fixes 2 things in one go, first of all the device_destroy bus
op should be a device_detach bus op, as pending async packets from the
device should be cancelled on detach not on destroy.

Secondly having this as a bus op won't work with companion controllers, since
then there will be 1 bus driven by the ehci controller and thus 1 set of bus
ops, but the device being detached may be downstream of a handed over port.
Making the detach of a downstream device a port op allows the ehci controller
to forward this to the companion controller port for handed over ports.

Paolo Bonzini 7447545544 change all other clock references to use nanosecond resolution accessors
This was done with:

    sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \
        $(git grep -l 'qemu_get_clock\>' )
    sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \
        $(git grep -l 'qemu_new_timer\>' )

after checking that get_clock and new_timer never occur twice
on the same line.  There were no missed occurrences; however, even
if there had been, they would have been caught by the compiler.

There was exactly one false positive in qemu_run_timers:

     -    current_time = qemu_get_clock (clock);
     +    current_time = qemu_get_clock_ns (clock);

which is of course not in this patch.
