ddcf4730ce drivers: use virDirRead API
Convert all remaining clients of readdir to use the new
interface, so that we can ensure (unlikely) errors while
reading a directory are reported.

* src/openvz/openvz_conf.c (openvzAssignUUIDs): Use new
interface.
* src/parallels/parallels_storage.c (parallelsFindVolumes)
(parallelsFindVmVolumes): Report readdir failures.
* src/qemu/qemu_driver.c (qemuDomainSnapshotLoad): Ignore readdir
failures.
* src/secret/secret_driver.c (loadSecrets): Likewise.
* src/qemu/qemu_hostdev.c
(qemuHostdevHostSupportsPassthroughVFIO): Report readdir failures.
* src/xen/xen_inotify.c (xenInotifyOpen): Likewise.
* src/xen/xm_internal.c (xenXMConfigCacheRefresh): Likewise.

2835c1e730 Add virLogSource variables to all source files
Any source file which calls the logging APIs now needs
to have a VIR_LOG_INIT("source.name") declaration at
the start of the file. This provides a static variable
of the virLogSource type.

fd243fc4ad qemu: Don't fail if the SCSI host device is shareable between domains
It doesn't make sense to fail if the SCSI host device is specified
as "shareable" explicitly between domains (NB, it works if and only
if the device is specified as "shareable" for *all* domains,
otherwise it fails).

To fix the problem, this patch introduces an array for virSCSIDevice
struct, which records all the names of domain which are using the
device (note that the recorded domains must specify the device as
shareable).  And the change on the data struct brings on many
subsequent changes in the code.

Prior to this patch, the "shareable" tag didn't work as expected,
it actually work like "non-shareable".  So this patch also added notes
in formatdomain.html to declare the fact.

* src/util/virscsi.h:
  - Remove virSCSIDeviceGetUsedBy
  - Change definition of virSCSIDeviceGetUsedBy and virSCSIDeviceListDel
  - Add virSCSIDeviceIsAvailable

* src/util/virscsi.c:
  - struct virSCSIDevice: Change "used_by" to be an array; Add
    "n_used_by" as the array count
  - virSCSIDeviceGetUsedBy: Removed
  - virSCSIDeviceFree: frees the "used_by" array
  - virSCSIDeviceSetUsedBy: Copy the domain name to avoid potential
    memory corruption
  - virSCSIDeviceIsAvailable: New
  - virSCSIDeviceListDel: Change the logic, for device which is already
    in the list, just remove the corresponding entry in "used_by". And
    since it's only used in one place, we can safely removing the code
    to find out the dev in the list first.
  - Copyright updating

* src/libvirt_private.sys:
  - virSCSIDeviceGetUsedBy: Remove
  - virSCSIDeviceIsAvailable: New

* src/qemu/qemu_hostdev.c:
  - qemuUpdateActiveScsiHostdevs: Check if the device existing before
    adding it to the list;
  - qemuPrepareHostdevSCSIDevices: Error out if the not all domains
    use the device as "shareable"; Also don't try to add the device
    to the activeScsiHostdevs list if it already there; And make
    more sensible error w.r.t the current "shareable" value in
    driver->activeScsiHostdevs.
  - qemuDomainReAttachHostScsiDevices: Change the logic according
    to the changes on helpers.

Unlike the host devices of other types, SCSI host device XML supports
"shareable" tag. This patch introduces it for the virSCSIDevice struct

preparing the SCSI host device in QEMU driver).

47b9aae0ae qemu: default to vfio for nodedev-detach
This patch resolves:

  https://bugzilla.redhat.com/show_bug.cgi?id=1035188

Commit f094aaac48 changed the PCI device assignment in qemu domains
to default to using VFIO rather than legacy KVM device assignment
(when VFIO is available). It didn't change which driver was used by
default for virNodeDeviceDetachFlags(), though, so that API (and the
virsh nodedev-detach command) was still binding to the pci-stub
driver, used by legacy KVM assignment, by default.

This patch publicizes (only within the qemu module, though, so no
additions to the symbol exports are needed) the functions that check
for presence of KVM and VFIO device assignment, then uses those
functions to decide what to do when no driver is specified for
virNodeDeviceDetachFlags(); if the vfio driver is loaded, the device
will be bound to vfio-pci, or if legacy KVM assignment is supported on
this system, the device will be bound to pci-stub; if neither method
is available, the detach will fail.

5669045580 Resolve Coverity issue regarding not checking return value
Coverity complains that the call to virPCIDeviceDetach() in
qemuPrepareHostdevPCIDevices() doesn't check status return like
other calls.  Seems this just was lurking until a recent change
to this module resulted in Coverity looking harder and finding
the issue.  Introduced by 'a4efb2e33' when function was called
'pciReAttachDevice()'

Just added a ignore_value() since it doesn't appear to matter
if the call fails since we're on a failure path already.
