98f22dc172 usb-bus: fix no params
After commit 702f3e0fb5, the params is
nerver NULL. It should check *params instead of params to determine
whether the params is empty.

1ecda02b24 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
IFF_VNET_HDR available" (all three versions).

There's one place that passes arguments without newlines
intentionally: load_vmstate().  Fix it up.

d44168fffa 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.

556cd09885 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
name should be short & sweet.

063846984c 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
the value is still the same.

61e094c049 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):
 * attaching encrypted mass storage devices.
 * -usbdevice host:...

0958b4cc8f 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
for a usb driver with a matching name.  When a parameter parsing
callback is present it is called, otherwise the device is created via
usb_create_simple().

e23a1b33b5 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
we know that failure can't happen.

Because relying in the latter is somewhat unclean, and the former is
not always obvious, it would be nice to go back to qdev_init() in the
not-so-obvious cases, only with proper error handling.  I'm leaving
that for another day, because it involves making sure that error
values are properly checked by all callers.

a8e662b547 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 usb hub to qdev_free() all connected devices on unplug.
Unplugging a usb hub works now.

72cf2d4f0e 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 15cc923584,
f40d753718,
96555a96d7 and
3990d09adf but the fixes were fragile.

Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.

a5d2f7273c 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()
instead.

Kill some FIXMEs added by the first qdev/usb patch.
