renamed the 'rfb' keycode to 'qnum' and we need to accept the new

The storagePoolLookupByTargetPath() method in the storage driver is used
by the QEMU driver during block migration. If there's a valid use case
for this in the QEMU driver, then external apps likely have similar
needs. Exposing it in the public API removes the direct dependancy from
the QEMU driver to the storage driver.

So we have a syntax-check rule to catch all tab indents but it naturally
can't catch tab spacing, i.e. as a delimiter. This patch is a result of
running 'vim -en +retab +wq'
(using tabstop=8 softtabstop=4 shiftwidth=4 expandtab) on each file from
a list generated by the following:

The command "info migrate" of qemu outputs the dirty-pages-rate during
migration, but page size is different in different architectures. So
page size should be output to calculate dirty pages in bytes.
Page size is already implemented with commit

There are only two acceptable places for describing enum values.
It's either:
typedef enum {
/* Some long description. Therefore it's placed before
* the value. */
VIR_ENUM_A_VAL = 1,
} virEnumA;
or:
typedef enum {
VIR_ENUM_B_VAL = 1, /* Some short description */
} virEnumB;
However, during review of a patch sent upstream I realized that
is not always the case. I went through all the public header
files and identified all the offenders. Luckily there were just
two of them.
Yes, this makes our HTML generated documentation broken, but
that's bug of the generator. Our header files shouldn't be forced
to use something we don't want to.

All of these four functions (virStreamRecvAll, virStreamSendAll,
virStreamSparseRecvAll, virStreamSparseSendAll) take one or more
callback functions that handle various aspects of streams.
However, if any of them fails no error is reported therefore
caller does not know what went wrong.
At the same time, we silently presumed callbacks to set errno on
failure. With this change we should document it explicitly as the
error is not properly reported.

Allow starting the block-copy job for a persistent domain if a user
declares by using a flag that the job will not be recovered if the VM is
switched off while the job is active.
This allows to use the block-copy job with persistent VMs under the same
conditions as would apply to transient domains.
Now that the node_device driver is aware of CCW devices, let's hook up

QEMU will likely report the details of it shutting down, particularly
whether the shutdown was initiated by the guest or host. We should
forward that information along, at least for shutdown events. Reset
has that as well, however that is not a lifecycle event and would add
extra constants that might not be used. It can be added later on.

The reason for introducing two capabilities, one for the device itself
(cap 'mdev') and one for the parent device listing the available types
('mdev_types'), is that we should be able to do
'virsh nodedev-list --cap' not only for existing mdev devices but also
for devices that support creation of mdev devices, since one day libvirt
might be actually able to create the mdev devices in an automated way
(just like we do for NPIV/vHBA).

These flags to APIs will tell if caller wants to use sparse
stream for storage transfer. At the same time, it's safe to
enable them in storage driver frontend and rely on our backends
checking the flags. This way we can enable specific flags only on
some specific backends, e.g. enable
VIR_STORAGE_VOL_DOWNLOAD_SPARSE_STREAM for filesystem backend but
not iSCSI backend.

Add a new flag to virStreamRecvFlags in order to handle being able to
stop reading from the stream so that the consumer can generate a "hole"
in stream target. Generation of a hole replaces the need to receive and
handle a sequence of zero bytes for sparse stream targets.

This function is basically a counterpart for virStreamSendHole().
If one side of a stream called virStreamSendHole() the other
should call virStreamRecvHole() to get the size of the hole.

This API is used to tell the other side of the stream to skip
some bytes in the stream. This can be used to create a sparse
file on the receiving side of a stream.
It takes @length argument, which says how big the hole is. This
skipping is done from the current point of stream. Since our
streams are not rewindable like regular files, we don't need
@whence argument like seek(2) has.

When using thin provisioning, management tools need to resize the disk
in certain cases. To avoid having them to poll disk usage introduce an
event which will be fired when a given offset of the storage is written
by the hypervisor. Together with the API which will be added later, it
will allow registering thresholds for given storage backing volumes and
this event will then notify management if the threshold is exceeded.
Similarly to domainSetGuestVcpus this commit adds API which allows to
modify state of individual vcpus rather than just setting the count.
This allows to enable CPUs in specific guest NUMA nodes to achieve any
necessary configuration.
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.

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.
