Let's move some variables from an inside loop to global function
declaration header block. It's going to be easier for next
patches. At the same time, order the cleanup calls at the

There's no reason why debug initialization could not be made completely
hidden, just like readline initialization is. The point of the global
initializer vshInit is to make initialization of smaller features transparent
to the user/caller.
Currently, we set interactive mode as default possibly reverting the
setting after we parse the command line arguments. There's nothing
particulary wrong with that, but a call to vshReadlineInit is performed
always in the global initializer just because the default mode is interactive.
Rather than moving vshReadlineInit call somewhere else (because another client
might want to implement interactive mode only), we could make the decision
if we're about to run in interactive mode once the command line is parsed.
Commit a0b6a36f separated vshInitDebug from the original vshInit
(before virsh got split and vshInit became virshInit - commit 834c5720)
in order to be able to debug command line parsing.
After the parsing is finished, debugging is reinitialized to work properly.
There might as well be other features that require re-initialization as
the command line could specify parameters that override our defaults which
had been set prior to calling vshArgvParse.
As part of the effort to stay consistent, change the vshInit signature
from returning int to returning bool. Moreover, remove the
unnecessary error label as there is no cleanup that would make use of
it.
Caller is responsible for freeing the result of virStringJoin()
when no longer needed:

Adds a new interface type using UDP sockets, this seems only applicable
to QEMU but have edited tree-wide to support the new interface type.
The interface type required the addition of a "localaddr" (local
address), this then maps into the following xml and qemu call.
<interface type='udp'>
<mac address='52:54:00:5c:67:56'/>
<source address='127.0.0.1' port='11112'>
<local address='127.0.0.1' port='22222'/>
</source>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
</interface>
QEMU call:
-net socket,udp=127.0.0.1:11112,localaddr=127.0.0.1:22222
Notice the xml "local" entry becomes the "localaddr" for the qemu call.

When looking up a domain, we try to look up by ID, UUID and NAME
consequently while not really caring which of those lookups succeeds.
The problem is that if any of them fails, we dispatch the error from the
driver and that means setting both threadlocal and global error. Let's
say the last lookup (by NAME) succeeds and resets the threadlocal error as any
other API does, however leaving the global error unchanged. If the underlying
virsh command does not succeed afterwards, our cleanup routine in
vshCommandRun ensures that no libvirt error will be forgotten and that's
exactly where this global error comes in incorrectly.
# virsh domif-setlink 123 vnet1 up
error: interface (target: vnet1) not found
error: Domain not found: no domain with matching id 123
This patch also resets the global error which would otherwise cause some
minor confusion in reported error messages.

This patch removes the static keyword from the vshReadline which was
introduced in commit 834c5720e4. With
readline the vshReadline function is not static but when compiling
without readline it was defined as static which caused compilation
error.
In order to share as much virsh' logic as possible with upcomming
virt-admin client we need to split virsh logic into virsh specific and
client generic features.
Since majority of virsh methods should be generic enough to be used by
other clients, it's much easier to rename virsh specific data to virshX
than doing this vice versa. It moved generic virsh commands (including info
and opts structures) to generic module vsh.c.
Besides renaming methods and structures, this patch also involves introduction
of a client specific control structure being referenced as private data in the
original control structure, introduction of a new global vsh Initializer,
which currently doesn't do much, but there is a potential for added
functionality in the future.
Lastly it introduced client hooks which are especially necessary during
client connecting phase.
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 #

Commit 6983d6d2 tried to improve parseRateStr but broke the build

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);

if (virStrToLong_ullp(token, NULL, 10, tmp) < 0) {

Rather than trying to fix the code, refactor the function again by
reusing virStringSplit.
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]]]

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.

Reuse the vshBlockJobWait infrastructure to refactor cmdBlockCommit to
use the common code. This additionally fixes a bug when working with
new qemus, where when doing an active commit with --pivot the pivoting
would fail, since qemu reaches 100% completion but the job doesn't
switch to synchronized phase right away.
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.
Use the VSH_EXCLUSIVE_OPTIONS to exclude combinations of --pivot and
--keep-overlay and refactor the enforcing of the --wait option and other
flags that imply --wait.
Use the VSH_EXCLUSIVE_OPTIONS_VAR to interlock incompatible options.
Since a variable named 'abort' would conflict with older compilers use
VSH_EXCLUSIVE_OPTIONS for the --abort option.

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.

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.
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.
