usb-bus: fix no params

After commit 702f3e0fb52c124c07f215426eeadb70a716643f, the params is
nerver NULL. It should check *params instead of params to determine
whether the params is empty.

Avoid crash on '-usbdevice <device>' without parameters

Many usbdevice_init implementors assume params is non-NULL.

error: Replace qemu_error() by error_report()

error_report() terminates the message with a newline. Strip it it
from its arguments.

This fixes a few error messages lacking a newline:
net_handle_fd_param()'s "No file descriptor named %s found", and
tap_open()'s "vnet_hdr=1 requested, but no kernel support for...

Fix -usbdevice crash

If -usbdevice is used on a machine with no USB busses, usb_create
will fail and return NULL. Patch below handles this failure gracefully
rather than crashing when we try to init the device.

qdev: Rename USBDevice member devname to product_desc

It's not a device name, it's the USB product description string.

qdev: Separate USB product description from qdev name

Using the qdev name for the product description makes for inconvenient
qdev names.

Put the product description in new USBDeviceInfo member product_desc.
Make usb_qdev_init() use it. No user or guest visible change, since...

qdev: Replace device names containing whitespace

Device names with whitespace require quoting in the shell and in the
monitor. Some of the offenders are also overly long. Some have a
more convenient alias, some don't.

The place for verbose device names is DeviceInfo member desc. The...

usb: make attach optional.

Add a auto_attach field to USBDevice, which is enabled by default.
USB drivers can clear this field in case they do not want the device
being attached (i.e. plugged into a usb port) automatically after
successfull init().

Use cases (see next patches):...

usb core: use qdev for -usbdevice

This patchs adds infrastructure to handle -usbdevice via qdev callbacks.
USBDeviceInfo gets a name field (for the -usbdevice driver name) and a
callback for -usbdevice parameter parsing.

The new usbdevice_create() function walks the qdev driver list and looks...

New qdev_init_nofail()

Like qdev_init(), but terminate program via hw_error() instead of
returning an error value.

Use it instead of qdev_init() where terminating the program on failure
is okay, either because it's during machine construction, or because...

usb: hook unplug into qdev, cleanups + fixes.

Hook into DeviceInfo->exit().

handle_destroy() must not free the state struct, this is handled
by the new usb_qdev_exit() function now.

qdev_free(usb_device) works now.

Fix sys-queue.h conflict for good

Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896,...

qdev/usb: make qemu aware of usb busses.

Move usb code from vl.c to usb-bus.c and make it use the new data
structures added by qdev conversion. qemu usb core should be able
to handle multiple USB busses just fine now (untested though).

Kill some usb_*_init() legacy functions, use usb_create_simple()...
