ff486e0d29 virsh: Implement "domrename" command
This patch implements new virsh command, domrename.

Using domrename, it will be possible to rename domain from the virsh shell by
calling virRenameDomain API.

It takes two arguments, current domain name and new domain name.

Example:

virsh # list --all
 Id    Name                           State
 ----------------------------------------------------
  -     bar                            shut off

virsh # domrename bar foo
Domain successfully renamed

virsh # list --all
 Id    Name                           State
 ----------------------------------------------------
  -     foo                            shut off

virsh #

73ca6f98a3 virsh: Refactor parseRateStr to avoid false-positive uninitialized variable
Commit 6983d6d2 tried to improve parseRateStr but broke the build
instead for compilers that were not able to properly introspect the for
loop indexed by the enum resulting into the following error:

virsh-domain.c: In function 'parseRateStr':
virsh-domain.c:916:13: error: 'field_name' may be used uninitialized in this function [-Werror=maybe-uninitialized]
             vshError(ctl, _("malformed %s field"), field_name);

virsh-domain.c:915:13: error: 'tmp' may be used uninitialized in this function [-Werror=maybe-uninitialized]
         if (virStrToLong_ullp(token, NULL, 10, tmp) < 0) {
             ^
Rather than trying to fix the code, refactor the function again by
reusing virStringSplit.

d7f5c88961 virsh: Implement VIR_DOMAIN_BANDWIDTH_IN_FLOOR
We have a function parseRateStr() that parses --inbound and
--outbound arguments to both attach-interface and domiftune.
Now that we have all virTypedParams macros needed for QoS,
lets parse even floor attribute. The extended format for the
arguments looks like this then:

  --inbound average[,peak[,burst[,floor]]]

6983d6d2c3 virsh: Rework parseRateStr
The function is used to parse a tuple delimited by commas into
virNetDevBandwidth structure. So far only three out of fore
fields are supported: average, peak and burst. The single missing
field is floor. Well, the parsing works, but I think we can do
better. Especially when we will need to parse floor too in very
close future.

2e78276364 virsh: Refactor block job waiting in cmdBlockPull
Introduce helper function that will provide logic for waiting for block
job completion so the 3 open coded places can be unified and improved.

This patch introduces the whole logic and uses it to fix
cmdBlockJobPull. The vshBlockJobWait function provides common logic for
block job waiting that should be robust enough to work across all
previous versions of libvirt. Since virsh allows passing user-provided
strings as paths of block devices we can't reliably use block job events
for detection of block job states so the function contains a great deal
of fallback logic.

f69ece073e virsh: Teach cmdFreepages to work with lxc driver
Some drivers don't expose available huge page sizes in the
capabilities XML. For instance, LXC driver is one of those.
This has a downside that when virsh is trying to get
aggregated info on free pages per all NUMA nodes, it fails.
The problem is that the virNodeGetFreePages() API expects
caller to pass an array of page sizes he is interested in.
In virsh, this array is filled from the capabilities from
'/capabilities/host/cpu/pages' XPath. As said, in LXC
there's no such XPath and therefore virsh fails currently.
But hey, we can fallback: the page sizes are exposed under
'/capabilities/host/topology/cells/cell/pages'. The page
size can be collected from there, and voilà the command
works again. But now we must make sure that there are no
duplicates in the array passed to the public API. Otherwise
we won't get as beautiful output as we are getting now.

a02a161bb8 qemu: libxl: vcpupin: Don't reset pinning when pinning to all pcpus
In the pre-NUMA ages pinning a vCPU to all pCPUs was eaqual to deleting
the pinning info. Now it does not entirely work that way. Pinning a vCPU
to all pCPUs might be a desired operation. Additionally removal of the
pinning will result into using the default pinning information at the
next boot which might be different from all vcpus.

This patch removes the false assumption that we should remove the
pinning after pinning to all vCPUs and tweaks the documentation for
virsh.

A later patch will implement a new flag for the virDomainPinVcpuFlags
API that will allow to remove the pinning in a sane way.

e9507fd41c virsh: Fix Ctrl-C behavior when watching a job
When watching a job (save, managedsave, dump, migrate) virsh spawns a
thread to call the appropriate API and waits for the result while
watching for interruption signals (SIGINT, Ctrl-C on the terminal).
Whenever such signal is caught, virsh calls virDomainAbortJob, stops
waiting for the job, and returns the result of virDomainAbortJob.

This is wrong because the job might have finished in the meantime or it
might have been cancelled by someone else and virsh would just report
the failure to abort the job. However, we are not interested in the
virDomainAbortJob's result at all, we need to keep waiting for the main
job to finish and report its result instead.

A negative value only makes sense as a delta. Imply the
