The function is actually in virutil.c, but prototyped in virfile.h.
This patch fixes that by renaming the function to virWaitForDevices,
adding the prototype in virutil.h and libvirt_private.syms, and then
changing the callers to use the new name.

cpuNodeData has always been followed by cpuDecode as no hypervisor
driver is really interested in raw CPUID data for a host CPU. Let's
create a new CPU driver API which returns virCPUDefPtr directly.

Move all the NWFilterObj API's into their own module virnwfilterobj
from the nwfilter_conf
Purely code motion at this point, plus adjustments to cleanly build.
Whole implementations along with helper totalling screens of code were
conditionally compiled. That made the code totally unreadable and
untestable. Rename functions to have the architecture in the name so
that all can be compiled at the same time and introduce header to allow
testing them all.
After the system has been booted, it should not change.
Cache the return value of virSystemdHasMachined.
Allow starting and terminating machines with just one
DBus call, instead of three, reducing the chance of
the call timing out.
Also introduce a small function for resetting the cache

Rework the code to perform the various searches by parent, parent_wwnn/
parent_wwpn, parent_fabric_wwn, or vport capable in order to return the
'parent_host' number that is vHBA capable.
The former virNodeDeviceGetParentHost is renamed to add the ByParent
on it fixes an issue where if no parent was supplied in the XML to
create the vHBA, then virNodeDeviceFindByName was called with a NULL
second parameter which had bad results.
The reworked code will make the various calls to fetch the NPIV host
by the passed parameter options or if none are provided find a vport
capable NPIV HBA to perform the create. If the call is from the delete
path, then this option won't be allowed.
Each of virNodeDeviceGetParentHostBy* functions is now static, so
remove them external definitions.
A secondary benefit of this is the test_driver now can make use of
the new API to add some new tests to test the various creation options.
Create a virscsihost.c and place the functions there. That removes the
last #ifdef __linux__ from virutil.c.
Take the opporunity to also change the function names and in one case
the parameters slightly
Use the new virNodeDeviceGetParentName instead. Modify the callers to
build the node device scsi_host# name string in order to call the new
function so that proper lookup occurs.
Rather than have them mixed in with the virutil apis, create a separate
virvhba.c module and move the vHBA related calls into there. Soon there
will be more added.
Also modify the names of the functions and some arguments to be more
indicative of what is really happening. Adjust the callers respectively.
While I was changing fchosttest, rather than the non-descriptive names
test1...test6, rename them to match what the test is doing.
So rather than comparing 2 paths (strings) as they are, which can very
easily lead to unnecessary errors (e.g. in storage driver) that the paths
are not the same when in fact they'd be e.g. just symlinks to the same
location, we should put our best effort into resolving any symlinks and
canonicalizing the path and only then compare the 2 paths for equality.

Based on work of Mehdi Abaakouk <sileht@sileht.net>.
When parsing vhost-user interface XML and no ifname is found we
can try to fill it in in post parse callback. The way this works
is we try to make up interface name from given socket path and
then ask openvswitch whether it knows the interface.

This is a simple wrapper over mount(). However, not every system
out there is capable of moving a mount point. Therefore, instead
of having to deal with this fact in all the places of our code we
can have a simple wrapper and deal with this fact at just one
place.

Other drivers (like qemu) would like to know if the namespaces
are available therefore it makes sense to move this function to
a shared module.
At the same time, this function had some default namespaces that
are checked with every call. It is not necessary - let callers
pass just those namespaces they are interested in.
With the move the function is renamed to
virProcessNamespaceAvailable.

Surprisingly there was a virDomainPCIAddressReleaseAddr() function
already, but it was completely unused. Since we don't reserve entire
slots at once any more, there is no need to release entire slots
either, so we just replace the single call to
virDomainPCIAddressReleaseSlot() with a call to
virDomainPCIAddressReleaseAddr() and remove the now unused function.
The keen observer may be concerned that ...Addr() doesn't call
virDomainPCIAddressValidate(), as ...Slot() did. But really the
validation was pointless anyway - if the device hadn't been suitable
to be connected at that address, it would have failed validation
before every being reserved in the first place, so by definition it
will pass validation when it is being unplugged. (And anyway, even if
something "bad" happened and we managed to have a device incorrectly
at the given address, we would still want to be able to free it up for
use by a device that *did* validate properly).
Since we don't actually reserve an entire slot at a time anymore, the
name of this function is just confusing, and it's almost identical in
operation to virDomainPCIAddressReserveNextAddr() anyway, so remove
the *Slot() function and replace calls to it with calls to *Addr(...,
-1).
This utility function iterates through all devices looking for any
with a PCI address that has function != 0 (which implies that multiple
functions are in use on that slot), then uses an inner iterator to
find the device that's on function 0 of that same slot and sets the
"multi" in its virDomainDeviceInfo (as long as it hasn't already been
set explicitly by someone who presumably has better information than
we do).
It isn't yet called from anywhere, so will have no functional effect.

With our new qemu namespace code in place, the relabelling of
devices is done not as good is it could: a child process is
spawned, it enters the mount namespace of the qemu process and
then runs desired API of the security driver.
Problem with this approach is that internal state transition of
the security driver done in the child process is not reflected in
the parent process. While currently it wouldn't matter that much,
it is fairly easy to forget about that. We should take the extra
step now while this limitation is still fresh in our minds.
Three new APIs are introduced here:
virSecurityManagerTransactionStart()
virSecurityManagerTransactionCommit()
virSecurityManagerTransactionAbort()
The Start() is going to be used to let security driver know that
we are starting a new transaction. During a transaction no
security labels are actually touched, but rather recorded and
only at Commit() phase they are actually updated. Should
something go wrong Abort() aborts the transaction freeing up all
memory allocated by transaction.

The public virSecret object has a single "usage_id" field
but the virSecretDef object has a different 'char *' field
for each usage type, but the code all assumes every usage
type has a corresponding single string. Get rid of the
pointless union in virSecretDef and just use "usage_id"
everywhere. This doesn't impact public XML format, only
