Alter the formatting of each line to not give the appearance of
one long run-on sentence and to be consistent between the various
elements of collected/displayed data. The formatting should fit
within the 80 character display. This removes the need for commas
at the end of each line.
After 7f1bdec5fa our nodedev driver is capable of
determining DRM devices (DRM stands for Direct Render Manager not
Digital rights management). There is still one bit missing
though: virConnectListAllNodeDevices() is capable of listing
either all devices or just those with specified capability. Well,
DRM capability is missing there.

All options started with underscores, but we switched them to dashes
later on, making the style consistent. The latest addition, however,
did not respect that, so let's change that as well. It is tempting to
just change the name instead of adding alias, especially since nobody
ever used it, which we know thanks to the fact that it didn't work.

Rather than have the Disk code having to use PARTED to determine if
there's something on the device, let's use the virStorageBackendDeviceProbe.
and only fallback to the PARTED probing if the BLKID code isn't built in.
This will also provide a mechanism for the other current caller (File
System Backend) to utilize a PARTED parsing algorithm in the event that
BLKID isn't built in to at least see if *something* exists on the disk
before blindly trying to use. The PARTED error checking will not find
file system types, but if there is a partition table set on the device,
it will at least cause a failure.
Move virStorageBackendDiskValidLabel and virStorageBackendDiskFindLabel
to storage_backend and rename/rework the code to fit the new model.
Update the virsh.pod description to provide a more generic description
of the process since we could now use either blkid or parted to find
data on the target device.

Commit id '27758859' introduced the "NO_OVERWRITE" flag check for
file system backends; however, the implementation, documentation,
and algorithm was inconsistent. For the "flag" description for the
API the flag was described as "Do not overwrite existing pool";
however, within the storage backend code the flag is described
as "it probes to determine if filesystem already exists on the
target device, renurning an error if exists".
The code itself was implemented using the paradigm to set up the
superblock probe by creating a filter that would cause the code
to only search for the provided format type. If that type wasn't
found, then the algorithm would return success allowing the caller
to format the device. If the format type already existed on the
device, then the code would fail indicating that the a filesystem
of the same type existed on the device.
The result is that if someone had a file system of one type on the
device, it was possible to overwrite it if a different format type
was specified in updated XML effectively trashing whatever was on
the device already.
This patch alters what NO_OVERWRITE does for a file system backend
to be more realistic and consistent with what should be expected when
the caller requests to not overwrite the data on the disk.
Rather than filter results based on the expected format type, the
code will allow success/failure be determined solely on whether the
blkid_do_probe calls finds some known format on the device. This
adjustment also allows removal of the virStoragePoolProbeResult
enum that was under utilized.
If it does find a formatted file system different errors will be
generated indicating a file system of a specific type already exists
or a file system of some other type already exists.
In the original virsh support commit id 'ddcd5674', the description
for '--no-overwrite' within the 'pool-build' command help output
has an ambiguous "of this type" included in the short description.
Compared to the longer description within the "Build a given pool."
section of the virsh.pod file it's more apparent that the meaning
of this flag would cause failure if a probe of the target already
has a filesystem.
So this patch also modifies the short description to just be the
antecedent of the 'overwrite' flag, which matches the API description.
This patch also modifies the grammar in virsh.pod for no-overwrite
as well as reworking the paragraph formats to make it easier to read.

The virsh manpage lists "shutdown" and "dying" as two of the possible
domain states that could be listed in the output of the "virsh list"
command. However, a domain that is being shutdown will be listed as
"in shutdown", and the "dying" state doesn't even exist (and never
has, as far as I can tell from looking through git history - it was
shown in the original import of the virsh.pod file in 2006; there was
no VIR_DOMAIN_DYING state then, there wasn't one when those lines of
virsh.pod were tweaked in 2008, and there still isn't one
today. Apparently it was just something that sounded like a good idea
to someone at some time, but was never implemented...)

Add a new qualifier '--physical' to the 'vol-info' command in order to
dispaly the physical size of the volume. The size can differ from the
allocation value depending on the volume file time. In particular, qcow2
volumes will have a physical value larger than allocation. This also occurs
for sparse files, although for those the capacity is the largest size;
whereas, for qcow2 capacity is the logical size.
