Product and vendor values were swapped in the XML, which made virt-manager
PCI device listing kinda useless.

We were over-writing a pointer without freeing it in
case of a disk device, leading to a memory leak.

The virConnectPtr is no longer required for error reporting since

It was used for error reporting only.

The original udev node device backend neglected to lock the driverState
struct containing the device list when adding and removing devices
* src/node_device/node_device_udev.c: add necessary locks in
  udevRemoveOneDevice() and udevAddOneDevice()

udevGetUintProperty was called with base set to 0 for busnum and devnum.
With base 0 strtoul parses the number as octal if it start with a 0. But
busnum and devnum are decimal and udev returns them padded with leading
zeros. So strtoul parses them as octal. This works for certain decimal
values like 001-007, but fails for values like 008.

Change udevProcessUSBDevice to use base 10 for busnum and devnum.

it causes a NULL-dereference on some systems like Solaris 10.
* src/node_device/node_device_linux_sysfs.c. Include <stdlib.h>.
(get_sriov_function): Use canonicalize_file_name, not realpath.

This fixes a segfault when the event handler is called after shutdown
when the global driver state is NULL again.

Also fix a locking issue in an error path.

Two files were using functions from <sys/stat.h> but not including

I noticed some debug messages are printed with an empty lines after
them. This patch removes these empty lines from all invocations of the
following macros:
    VIR_DEBUG
    VIR_DEBUG0
    VIR_ERROR
    VIR_ERROR0
    VIR_INFO
    VIR_WARN
    VIR_WARN0

We are setting the same property two different ways without
free'ing in between. Just drop the second assignment.

There are quite a few differences between how udev exposes legacy
and USB floppy devs, but this patch takes care of both variants.

udev doesn't prefix USB product/vendor info with '0x', so the
strtol conversions were wrong for the product field (vendor already
set the correct base). Make the change for PCI product/vendor as
well to be safe.

This fixes USB device assignment via virt-manager.

older kernels such as 2.6.26 have it there.

This invalid free results in heap corruption. Some symptoms I saw
because of this were libvirtd crashing and virt-manager hanging
while trying to enumerate devices.

* src/node_device/node_device_driver.c (update_driver_name): The
previous code would write one byte beyond the end of the 4KiB
stack buffer when presented with a symlink value of exactly that
length (very unlikely).  Remove the automatic buffer and use
virFileResolveLink in place of readlink.  Suggested by Daniel Veillard.

src/node_device/node_device_udev.c was using a function available only
on the daemon code, fix this and use the function available globally

* src/node_device/node_device_udev.c: replace use of virEventAddHandleImpl
  by virEventAddHandle
