cbbbe7b448 datatypes: Rename @parent to @parentName in virNodeDevice
In next patches this name will be needed for a different memeber.
Also, it makes sense to rename the variable because it does not
contain reference to parent device, just its name.

7aa0e8c0cb storage: export virStoragePoolLookupByTargetPath as a public API
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.

085e794a86 lib: Introduce event for tracking disk backing file write threshold
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.

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.

0330848207 Promote storage pool refresh lifecycle event to top level event
The VIR_STORAGE_POOL_EVENT_REFRESHED constant does not
reflect any change in the lifecycle of the storage pool.

It should thus not be part of the storage pool lifecycle
event set, but rather be a top level event in its own
right. Thus we introduce VIR_STORAGE_POOL_EVENT_ID_REFRESH
to replace it.

fa5c5580d6 Introduce virNodeAllocPages
A long time ago in a galaxy far, far away it has been decided
that libvirt will manage not only domains but host as well. And
with my latest work on qemu driver supporting huge pages, we miss
the cherry on top: an API to allocate huge pages on the run.
Currently users are forced to log into the host and adjust the
huge pages pool themselves.  However, with this API the problem
is gone - they can both size up and size down the pool.
