IS_USB2_CONTROLLER() is useful in more places aside from just when
assigning PCI addresses in QEMU, and is checking for enum values that
are all defined in conf/domain_conf.h anyway, so define it there
instead.

Add .domainInterfaceAddresses so that user can have a way to
get domain interface address by 'virsh domifaddr'. Currently
it only supports '--source lease'.

Add support for the slic_table to the security drivers.

<os>
  <acpi>
    <table type="slic">/path/to/acpi/table/file</table>
  </acpi>
</os>

will result in:

-acpitable sig=SLIC,file=/path/to/acpi/table/file

This option was introduced by QEMU commit 8a92ea2 in 2009.

Add a new element to <domain> XML:
<os>
  <acpi>
    <table type="slic">/path/to/acpi/table/file</table>
  </acpi>
</os>

To supply a path to a SLIC (Software Licensing) ACPI
table blob.

The qemu-1.6.50 is a beta before the new minor version, let's replace it with
the release qemu-1.7.0.

This refactor also makes a distinction between the pointer to the
original definition and copied one to prevent mixups.

Use virDomainCputune struct to store the data rather than exploding the
fields and use macros to fill the typed params.

cgroup functions set and get the longer type so use it everywhere

Get rid of lots of duplicated code.

Introduce a macro to assign the parameters to avoid the for loop and
shuffle around various checks for a simpler and saner function.

Use virDomainObjGetDefs since the API guarantees that both live and
config are never set together.

The caller is already aware that the params are missing and the
extractor is ignoring the missing ones so the parameter isn't necessary.

ESX will refuse to attach VMDKS that have buslogic adatper type to 64bit
VMs whereas lsilogic works fine both 32bit and 64bit VMs.

Xen only supports network-based disks with the qemu (aka qdisk) driver.
Set the driverName to 'qemu' in libxlDomainDeviceDefPostParse() if
not already set. When starting a domain with network-based disks,
ensure the driverName is 'qemu'.

Resolves: https://bugzilla.opensuse.org/show_bug.cgi?id=981094

The libvirt internal bits can be changed for disks that don't otherwise
support changing media. Remove the switch statement and allow changes of
non-source data for all disks.

qemuDomainChangeDiskLive rolled back few changes to the disk definition
if changing of the media failed. This can be avoided by moving some code
around.

Commit id '15ccb0db' added job functions for the lxc driver; however,
for shutdown and nonpersistent path, the vm was removed from the domain
object list and the vm pointer cleared before the endjob.

Adjust the code to perform the endjob first and then perform the
ObjListRemove as long as the vm wasn't NULL. This follows more closely
models from qemu and libxl

Found by Coverity (FORWARD_NULL)

Based on some digital archaeology performed by jtomko, it's been determined
that the persistentAddrs variable is no longer necessary...

The variable was added by:
commit 141dea6b
CommitDate: 2010-02-12 17:25:52 +0000
    Add persistence of PCI addresses to QEMU

Where it was set to 0 on domain startup if qemu did not support the
QEMUD_CMD_FLAG_DEVICE capability, to clear the addresses at shutdown,
because QEMU might make up different ones next time.

As of commit f5dd58a6
CommitDate: 2012-07-11 11:19:05 +0200
    qemu: Extended qemuDomainAssignAddresses to be callable from
    everywhere.

this was broken, when the persistentAddrs = 0 assignment was moved
inside qemuDomainAssignPCIAddresses and while it pretends to check
for !QEMU_CAPS_DEVICE, its parent qemuDomainAssignAddresses is only
called if QEMU_CAPS_DEVICE is present.

Since commit id '20a0fa8e' removed the QEMU_CAPS_DEVICE, Coverity notes
that it's no longer possible to have 'addrs' be NULL when checking for
a live domain since qemuDomainPCIAddressSetCreate would have jumped to
cleanup if addrs was NULL.

Instead of setting the flag before parsing the PCI address, set
it afterwards. This ensure we can never end up in a situation
where the flag has been set but pci_dev.physical_function has
not been filled in.

Commit c8b1a836 changed the function, making it
impossible for callers to be able to tell whether a
non-negative return value means "physical function
address found and parsed correctly" or "couldn't find
corresponding physical function".

The important difference between the two being that,
in the latter case, the returned pointer is NULL and
should never, ever be dereferenced.

In order to cope with these changes, the callers
have to be updated.

Just an extra precaution in case the function returns early
due to an OOM error.

Use the detected tray presence flag to trigger the tray waiting code
only if the given storage device in qemu reports to have a tray.

This is necessary as the floppy device lost it's tray as of qemu commit:

commit abb3e55b5b718d6392441f56ba0729a62105ac56

    Revert "hw/block/fdc: Implement tray status"

Commit 1fad65d4 used a really big hammer
and overwrote the error message that might be reported by qemu if the
tray is locked. Fix it by reporting the error only if no error is
currently set.

Error after commit mentioned above:
error: internal error: timed out waiting for disk tray status update

New error:
error: internal error: unable to execute QEMU command 'eject': Tray of
device 'drive-ide0-0-0' is not open

The code grew rather convoluted. Extract it to a separate function.

Extract information for all disks and update tray state and source only
for removable drives. Additionally store whether a drive is removable
and whether it has a tray.

Move it to a more sane place since it's refreshing data about disks.

Extract whether a given drive has a tray and whether there is no image
inserted.

Negative logic for the image insertion is chosen so that the flag is set
only if we are certain of the fact.

When reviewing libxl vif typename series[0] I found a bug
on xen-xm formatter where "virsh domxml-to-native xen-xm file.xml"
can lead to a NULL dereference if the disk driver isn't specified.
Fix this by checking for driver before writing/testing it down.

This is identical to type='bridge', but without the "connect to a
bridge" part, so it can be handled by using the same functions (and
often even the same cases in switch statements), after renaming
virLXCProcessSetupInterfaceBridged() to virLXCProcessInterfaceTap()
and enhancing it to skip bridge-related items when brname == NULL.

To be truly useful, we need to support setting the ip address on the
host side veth as well as guest side veth (already supported for
type='bridge'), as well as setting the peer address for both.

The <script> element (supported by type='ethernet' in qemu) isn't
supported in this patch. An error is logged at domain start time if it
is encountered. This may be changed in a later patch.

This patch follows the pattern used in qemu driver regarding
reference counting.
It changes lxcDomObjFromDomain() to ref the domain (using
virDomainObjListFindByUUIDRef()) and adds virDomainObjEndAPI() which
should be the only function in which the return value of
virObjectUnref() is checked.  This makes all reference counting
deterministic and makes the code a bit clearer.
