The QEMU VNC client arg code has a long standing typo
of SASL_CONF_DIR when it should be SASL_CONF_PATH for
the env variable name.

When creating a new disk mirror the new struct is stored in a separate
variable until everything went well. The removed hunk would actually
remove existing mirror information for example when the api would be run
if a mirror still exists.

The function headers contain type on the same line as the name. When
combined with usage of ATTRIBUTE_UNUSED, the function headers were very
long. Shorten them by breaking the line after the type.

Some of the functions in the storage driver had their headers formatted
incorrectly.

virSecurityManagerSetDiskLabel and virSecurityManagerRestoreDiskLabel
don't have complementary semantics. Document the semantics to avoid
possible problems.

I'm going to add functions that will deal with individual image files
rather than whole disks. Rename the security function to make room for
the new one.

Rename them to comply with the naming policy.

The new VIR_CONNECT_COMPARE_CPU_FAIL_INCOMPATIBLE flag for
virConnectCompareCPU can be used to get an error
(VIR_ERR_CPU_INCOMPATIBLE) describing the incompatibility instead of the
usual VIR_CPU_COMPARE_INCOMPATIBLE return code.
Signed-off-by: NJiri Denemark <jdenemar@redhat.com>

When CPU comparison APIs return VIR_CPU_COMPARE_INCOMPATIBLE, the caller
has no clue why the CPU is considered incompatible with host CPU. And in
some cases, it would be nice to be able to get such info in a client
rather than having to look in logs.

To achieve this, the APIs can be told to return VIR_ERR_CPU_INCOMPATIBLE
error for incompatible CPUs and the reason will be described in the
associated error message.

Currently, only LXC has hostdev mode 'capabilities' support,
so the other drivers should forbid to define it in XML.
The hostdev mode check is added to devicesPostParseCallback()
for each hypervisor driver.

But there are some drivers lack function devicesPostParseCallback(),
so only add check for qemu, libxl, openvz, uml, xen, xenapi.

The parent directory doesn't necessarily need to be stored after we
don't mangle the path stored in the image. Remove it and tweak the code
to avoid using it.

Store backing chain paths as non-canonical. The canonicalization step
will be already taken. This will allow to avoid storing unnecessary
amounts of data.

After we don't test relative paths, remove even more unnecessary cruft
from the test code.

libvirt always uses an absolute path to address the top image of an
image chain. Our storage test tests also the relative path which won't
ever be used. Additionally it makes the test more complicated.

Now that we store only relative names in virStorageSource's member
relPath the backingRelative member is obsolete. Remove it and adapt the
code to the removal.

Separately remove the now unused variable.

Due to various refactors and compatibility with the virstoragetest the
relPath field of the virStorageSource structure was always filled either
with the relative name or the full path in case of absolutely backed
storage. Return its original purpose to store only the relative name of
the disk if it is backed relatively and tweak the tests.

Now that we changed ordering of the stored metadata so that the backing
store is described by the child element the test should reflect this
change too.

Remove the expected backing store field as it's actually described by
the next element in the backing chain, so there's no need for
duplication.

This patch introduces a function that will allow us to resolve a
relative difference between two elements of a disk backing chain. This
function will be used to allow relative block commit and block pull
where we need to specify the new relative name of the image to qemu.

This patch also adds unit tests for the function to verify that it works
correctly.

As we are doing with the enum structures, a cleanup in "src/qemu/"
directory was done now. All the enums that were defined in the
header files were converted to typedefs in this directory. This
patch includes all the adjustments to remove conflicts when you do
this kind of change. "Enum-to-typedef"'s conversions were made in
"src/qemu/qemu_{capabilities, domain, migration, hotplug}.h".

When looking for a port to allocate, the port allocator didn't take in
consideration ports that are statically set by the user.  Defining
these two graphics elements in the XML would cause an error, as the
port allocator would try to use the same port for the spice graphics
element:

    <graphics type='spice' autoport='yes'/>
    <graphics type='vnc' port='5900' autoport='no'/>

The new *[pP]ortReserved variables keep track of the ports that were
successfully tracked as used by the port allocator but that weren't
bound.

Introduce 3 new APIs, virNetworkGetDHCPLeases, virNetworkGetDHCPLeasesForMAC
and virNetworkDHCPLeaseFree.

* virNetworkGetDHCPLeases: returns the dhcp leases information for a given
     virtual network.

  For DHCPv4, the information returned:
  - Network Interface Name
  - Expiry Time
  - MAC address
  - IAID (NULL)
  - IPv4 address (with type and prefix)
  - Hostname (can be NULL)
  - Client ID (can be NULL)

  For DHCPv6, the information returned:
  - Network Interface Name
  - Expiry Time
  - MAC address
  - IAID (can be NULL, only in rare cases)
  - IPv6 address (with type and prefix)
  - Hostname (can be NULL)
  - Client DUID

  Note: @mac, @iaid, @ipaddr, @clientid are in ASCII form, not raw bytes.
  Note: @expirytime can 0, in case the lease is for infinite time.

* virNetworkGetDHCPLeasesForMAC: returns the dhcp leases information for a
     given virtual network and specified MAC Address.

* virNetworkDHCPLeaseFree: allows the upper layer application to free the
     network interface object conveniently.

There is no support for flags, so user is expected to pass 0 for
both the APIs.
