ce381d3764 vbox: Rewrite vboxStoragePoolNumOfVolumes
We use typedef IMedium IHardDisk to make IHardDisk hierachy from
IMedium (Actually it did on vbox 2.2 and 3.0's C++ API).
So when calling
    VBOX_MEDIUM_FUNC_ARG*(IHardDisk, func, args)
we can directly replace it to
    gVBoxAPI.UIMedium.func(IHardDisk, args)

When dealing with this two types, we get some rules from it's
hierachy relationship.

When using IHardDisk and IMedium as input, we can't transfer a
IMedium to IHardDisk. Like:
    gVBoxAPI.UIHardDisk.func(IHardDisk *hardDisk, args)
    Here, we can't put a *IMedium as a argument.

When using IHardDisk and IMedium as output, we can't transfer a
IHardDisk to IMedium. Like:
    gVBoxAPI.UIMachine.GetMedium(IMedium **out)
    Here, we can't put a **IHardDisk as a argument. If this case
    do happen, we either change the API to GetHardDisk or write a
    new one.

459886d41b vbox: Rewrite vbox-independent functions
This patch rewrites the following functions
    *vboxStorageOpen
    *vboxStorageClose
    *vboxConnectNumOfStoragePools
    *vboxConnectListStoragePools
    *vboxStoragePoolLookupByName

These functions do not call any vbox API, so I directly move it
from vbox_tmpl.c to vbox_storage.c

A small improvement is made on vboxConnectListStoragePools.
The if condition nnames == 1 is modified to nnames > 0. So if the
caller put more than one slot to get active storage pools, the new
function will return exactly one, while the old one would only
return 0.

7d5b9419f1 vbox: move common codes to vbox_common.h
There are lots of macro declarations in vbox_common.c,
vbox_network.c, and the coming vbox_storage.c which simply the API
calling. Since they are totally the same. We shouldn't keep three
copies of that, so they are moved to vbox_common.h.

Note: The macros are quite different from those in vbox_tmpl.c,
      because they are using different API.

a6b1cde3ca vbox: Remove VBOX_OBJECT_CHECK macro
We should follow the rules that CHECK macro only do checking works.
But this VBOX_OBJECT_CHECK and VBOX_OBJECT_HOST_CHECK declared some
varibles at the same time, which broke the rule. So the patch
removed this macros and dispatched it in source code.

The storage driver is still not rewriten at this point. So, I
remains the VBOX_OBJECT_CHECK macro in vbox_tmpl.c. But this will
finally be removed in patch 'vbox: Remove unused things in vbox_tmpl.c'

b7fe5a6555 qemu_agent: Produce more readable error messages
Not every error message from qemu-ga has to have the 'class' field
filled out. For instance, I've seen this error message lately:

  qemuAgentCheckError:1047 : unable to execute QEMU agent command \
  {"execute":"guest-set-time"}: \
  {"error":{"desc":"Invalid parameter type, expected: integer"}}

However, this got translated into rather generic error message:

  internal error: unable to execute QEMU agent command
  'guest-set-time': unknown QEMU command error

So we've dropped better error message in favor of a generic one.
This is due to our code which expects 'class' which is not
present here.

2086a9905a qemu: forbid snapshot-delete --children-only on external snapshot
https://bugzilla.redhat.com/show_bug.cgi?id=956506 documents that
given a domain where an internal snapshot parent has an external
snapshot child, we lacked a safety check when trying to use the
--children-only option to snapshot-delete:

$ virsh start dom
$ virsh snapshot-create-as dom internal
$ virsh snapshot-create-as dom external --disk-only
$ virsh snapshot-delete dom external
error: Failed to delete snapshot external
error: unsupported configuration: deletion of 1 external disk snapshots not supported yet
$ virsh snapshot-delete dom internal --children
error: Failed to delete snapshot internal
error: unsupported configuration: deletion of 1 external disk snapshots not supported yet
$ virsh snapshot-delete dom internal --children-only
Domain snapshot internal children deleted

While I'd still like to see patches that actually do proper external
snapshot deletion, we should at least fix the inconsistency in the
meantime.  With this patch:

$ virsh snapshot-delete dom internal --children-only
error: Failed to delete snapshot internal
error: unsupported configuration: deletion of 1 external disk snapshots not supported yet

* src/qemu/qemu_driver.c (qemuDomainSnapshotDelete): Fix condition.

f9f9699f40 util: eliminate "use after free" in callers of virNetDevLinkDump
virNetDevLinkDump() gets a message from netlink into "resp", then
calls nlmsg_parse() to fill the table "tb" with pointers into resp. It
then returns tb to its caller, but not before freeing the buffer at
resp. That means that all the callers of virNetDevLinkDump() are
examining memory that has already been freed. This can be verified by
filling the buffer at resp with garbage prior to freeing it (or, I
suppose, just running libvirtd under valgrind) then performing some
operation that calls virNetDevLinkDump().

The code has been like this ever since virNetDevLinkDump() was written
- the original author didn't notice it, and neither did later
additional users of the function. It has only been pure luck (or maybe
a lack of heavy load, and/or maybe an allocation algorithm in malloc()
that delays re-use of just-freed memory) that has kept this from
causing errors, for example when configuring a PCI passthrough or
macvtap passthrough network interface.

The solution taken in this patch is the simplest - just return resp to
the caller along with tb, then have the caller free it after they are
finished using the data (pointers) in tb. I alternately could have
made a cleaner interface by creating a new struct that put tb and resp
together along with a vir*Free() function for it, but this function is
only used in a couple places, and I'm not sure there will be
additional new uses of virNetDevLinkDump(), so the value of adding a
new type, extra APIs, etc. is dubious.

f2a2d0e9ab tests: Add SELINUX_LIBS to fix viridentitytest linker bug
In a clean build system (Ubuntu 14.04), the viridentitytest failed to compile.
Even if all the SELINUX libraries and depedencies are installed. See the error
message below:

Simply adding the variable SELINUX_LIBS in viridentitytest rules of

compilation issue.
