f62e418c86 virsh: Allow display of the physical volume size
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.

0c234889c4 storage: Introduce virStorageVolInfoFlags
https://bugzilla.redhat.com/show_bug.cgi?id=1332019

This function will essentially be a wrapper to virStorageVolInfo in order
to provide a mechanism to have the "physical" size of the volume returned
instead of the "allocation" size. This will provide similar capabilities to
the virDomainBlockInfo which can return both allocation and physical of a
domain storage volume.

NB: Since we're reusing the _virStorageVolInfo and not creating a new
_virStorageVolInfoFlags structure, we'll need to generate the rpc APIs
remoteStorageVolGetInfoFlags and remoteDispatchStorageVolGetInfoFlags
(although both were originally created from gendispatch.pl and then
just copied into daemon/remote.c and src/remote/remote_driver.c).

The new API will allow the usage of a VIR_STORAGE_VOL_GET_PHYSICAL flag
and will make the decision to return the physical or allocation value
into the allocation field.

In order to get that physical value, virStorageBackendUpdateVolTargetInfoFD
adds logic to fill in physical value matching logic in qemuStorageLimitsRefresh
used by virDomainBlockInfo when the domain is inactive.

78661cb1f4 conf: Display <physical> in output of voldef
Although the virStorageBackendUpdateVolTargetInfo will update the
target.physical value, there is no way to provide that information
via the virStorageGetVolInfo API since it only returns the capacity
and allocation of a volume. So as described in commit id '0282ca45',
it should be possible to generate an output only <physical> value
for that purpose.

This patch generates the <physical> value in the volume XML output
for the sole purpose of being able to view/see the value to allow
someone to parse the XML in order to obtain the value.

Update the documentation to describe the output only nature.

b9b1aa6392 qemu: Adjust qemuDomainGetBlockInfo data for sparse backed files
According to commit id '0282ca45a' the 'physical' value should
essentially be the last offset of the image or the host physical
size in bytes of the image container. However, commit id '15fa84ac'
refactored the GetBlockInfo to use the same returned data as the
GetStatsBlock API for an active domain. For the 'entry->physical'
that would end up being the "actual-size" as set through the
qemuMonitorJSONBlockStatsUpdateCapacityOne (commit '7b11f5e5').
Digging deeper into QEMU code one finds that actual_size is
filled in using the same algorithm as GetBlockInfo has used for
setting the 'allocation' field when the domain is inactive.

The difference in values is seen primarily in sparse raw files
and other container type files (such as qcow2), which will return
a smaller value via the stat API for 'st_blocks'. Additionally
for container files, the 'capacity' field (populated via the
QEMU "virtual-size" value) may be slightly different (smaller)
in order to accomodate the overhead for the container. For
sparse files, the state 'st_size' field is returned.

This patch thus alters the allocation and physical values for
sparse backed storage files to be more appropriate to the API
contract. The result for GetBlockInfo is the following:

 capacity: logical size in bytes of the image (how much storage
           the guest will see)
 allocation: host storage in bytes occupied by the image (such
             as highest allocated extent if there are no holes,
             similar to 'du')
 physical: host physical size in bytes of the image container
           (last offset, similar to 'ls')

NB: The GetStatsBlock API allows a different contract for the
values:

 "block.<num>.allocation" - offset of the highest written sector
                            as unsigned long long.
 "block.<num>.capacity" - logical size in bytes of the block device
                          backing image as unsigned long long.
 "block.<num>.physical" - physical size in bytes of the container
                          of the backing image as unsigned long long.

dbeaa7e666 cgroup: reduce complexity of controller disabling
This patch reduces the complexity of the filtering algorithm in
virCgroupDetect by first correcting the controller mask and then
checking for potential co-mounts without any correlating
controller mask modifications.

If you agree that this patch removes complexity and improves
readability it could simply be squashed into the first patch
of this series.

dfcfe0bb9c cgroup: unavailable controller prevents controller disabling
The cgroup controller filtering in virCgroupDetect does not work
properly if the following conditions are met:
1) the host system does not have a cgroup controller which
libvirt requests (unavailable controller) and
2) libvirt is configured to disable a controller (disabled controller) and
3) the disabled controller is located before the unavailable controller
in virCgroupController.

As an example: The memory controller is unavailable and the cpuset
controller is configured to be disabled.
In this scenario trying to start a domain results in the error
error: Controller 'cpuset' is not wanted, but 'memory' is co-mounted: Invalid argument

This error occurs when virCgroupDetect is called with a valid parent group.
The resulting group created by virCgroupCopyMounts holds for cpuset and
memory controller empty mount points. The filtering of disabled controllers
checks for co-mounts by comparing the mount points. The cpuset controller
causes the filtering to occur before the memory controller is marked as to be
ignored by modifying the controller mask since it is unavailable.
Therefore the co-mount detection logic compares the cpuset and memory controller
mount points and since both are empty the memory controller is regarded
erroneously as being co-mounted.

5a26d1ce12 Point to the new libvirt-go bindings
The github.com/rgbkrk/libvirt-go bindings were the most complete
bindings historically, but their API coverage stops at 1.2.4,
with exception of a couple of newer APIs.

The new bindings at http://libvirt.org/git/?p=libvirt-go.git;a=log
how have (almost[1]) 100% API coverage all the way to 2.5.0. They also
expose the APIs in a way that allows for much stronger go type
checking by the compiler, and expose typed parameters as explicit
structs. Finally the bindings are able to conditionally compile against
any libvirt version 1.2.0 -> 2.5.0 without use of go build tags.

Change the docs to point to these new bindings, since they'll be
a better bet for users long term.

[1] virEvent & virStream callbacks are still TODO to be fixed
    real soon.
