usb: split packet result into actual_length + status
Since with the ehci and xhci controllers a single packet can be larger
then maxpacketsize, it is possible for the result of a single packet
to be both having transferred some data as well as the transfer to have
an error.
An example would be an input transfer from a bulk endpoint successfully
receiving 1 or more maxpacketsize packets from the device, followed
by a packet signalling halt.
While already touching all the devices and controllers handle_packet /
handle_data / handle_control code, also change the return type of
these functions to void, solely storing the status in the packet. To
make the code paths for regular versus async packet handling more
uniform.
This patch unfortunately is somewhat invasive, since makeing the qemu
usb core deal with this requires changes everywhere. This patch only
prepares the usb core for this, all the hcd / device changes are done
in such a way that there are no functional changes.
This patch has been tested with uhci and ehci hcds, together with usb-audio,
usb-hid and usb-storage devices, as well as with usb-redir redirection
with a wide variety of real devices.
Note that there is usually no need to directly set packet->actual_length
form devices handle_data callback, as that is done by usb_packet_copy()

usb: Suppress bogus error when automatic usb-hub creation fails
USBDevice's realize method usb_qdev_realize() automatically creates a
usb-hub when only one port is left. Creating devices in realize
methods is questionable, but works.
If usb-hub creation fails, an error is reported to stderr, but the
failure is otherwise ignored. We then create the actual device using
the last port, which may well succeed.
Example:
$ qemu -nodefaults -S -display none -machine usb=on -monitor stdio
QEMU 2.2.50 monitor - type 'help' for more information
(qemu) device_add usb-mouse
[Repeat 36 times]

[More mice and hubs omitted...]
Device 0.0, Port 2.8.8.8.8.7, Speed 12 Mb/s, Product QEMU USB Mouse
(qemu) device_add usb-mouse

Device 0.0, Port 2.8.8.8.8.8, Speed 12 Mb/s, Product QEMU USB Mouse
Despite the "Failed" message, the command actually succeeded.
In QMP, it's worse. When adding the 37th mouse via QMP, the command
fails with
{"error": {"class": "GenericError", "desc": "usb hub chain too deep"}}
Additionally, "Failed to initialize USB device 'usb-hub'" is reported
on stderr. Despite the command failure, the device was created. This
is wrong.
Fix by avoiding qdev_init() for usb-hub creation, so we can ignore
errors cleanly.

followed by manual cleanup, first because I can't figure out how to
make Coccinelle transform strings, and second to get rid of now
superfluous error_propagate().
We now use or propagate the original error whole instead of just its
message obtained with error_get_pretty(). This avoids suppressing its
hint (see commit 50b7b00), but I can't see how the errors touched in
this commit could come with hints. It also improves the message
printed with &error_abort when we screw up (see commit 1e9b65b).

usb: Suppress bogus error when automatic usb-hub creation fails
USBDevice's realize method usb_qdev_realize() automatically creates a
usb-hub when only one port is left. Creating devices in realize
methods is questionable, but works.
If usb-hub creation fails, an error is reported to stderr, but the
failure is otherwise ignored. We then create the actual device using
the last port, which may well succeed.
Example:
$ qemu -nodefaults -S -display none -machine usb=on -monitor stdio
QEMU 2.2.50 monitor - type 'help' for more information
(qemu) device_add usb-mouse
[Repeat 36 times]
(qemu) info usb
Device 0.0, Port 1, Speed 12 Mb/s, Product QEMU USB Mouse
Device 0.0, Port 2, Speed 12 Mb/s, Product QEMU USB Hub
Device 0.0, Port 2.1, Speed 12 Mb/s, Product QEMU USB Mouse
[More mice and hubs omitted...]
Device 0.0, Port 2.8.8.8.8.7, Speed 12 Mb/s, Product QEMU USB Mouse
(qemu) device_add usb-mouse
usb hub chain too deep
Failed to initialize USB device 'usb-hub'
(qemu) info usb
[...]
Device 0.0, Port 2.8.8.8.8.7, Speed 12 Mb/s, Product QEMU USB Mouse
Device 0.0, Port 2.8.8.8.8.8, Speed 12 Mb/s, Product QEMU USB Mouse
Despite the "Failed" message, the command actually succeeded.
In QMP, it's worse. When adding the 37th mouse via QMP, the command
fails with
{"error": {"class": "GenericError", "desc": "usb hub chain too deep"}}
Additionally, "Failed to initialize USB device 'usb-hub'" is reported
on stderr. Despite the command failure, the device was created. This
is wrong.
Fix by avoiding qdev_init() for usb-hub creation, so we can ignore
errors cleanly.
