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.

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.
There's this condition:
flags & VIR_DOMAIN_AFFECT_CURRENT && virDomainIsActive(dom)
which can never be true since VIR_DOMAIN_AFFECT_CURRENT has hardcoded
value of zero. Therefore virDomainIsActive() is a dead code. However,
the condition could make sense if it is rewritten as the following:
!(flags & VIR_DOMAIN_AFFECT_CONFIG) && virDomainIsActive(dom)

Commit id '81dd81e' caused a regression when attempting to print a
specific vcpuid that is out of the range of the maximum vcpus for
the guest, such as:
$ virsh vcpupin $dom 1000
VCPU: CPU Affinity
----------------------------------
$
Rather than just recover the old message, let's adjust the message based
on what would be displayed for a similar failure in the set path, such as:
$ virsh vcpupin $dom 1000
error: vcpu 1000 is out of range of persistent cpu count 2
$ virsh vcpupin $dom 1000 --live
error: vcpu 1000 is out of range of live cpu count 2

When the block job would fail while watching it using the "--wait"
option for blockcopy, virsh would rather unhelpfully report:
$ virsh blockcopy vm hdc /tmp/raw.img --granularity 4096 --verbose --wait
Now in mirroring phase
Add a special case when the block job vanishes while waiting for it to
finish to improve the message:

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.

This will allow us to use vshError() to report errors from inside
vshCommandOpt*(), instead of replicating the same logic and error
messages all over the place.
We also have more context inside the vshCommandOpt*() functions,
for example the actual value used on the command line, which means
we can produce more detailed error messages.
vshCommandOptBool() is the exception here, because it's explicitly
designed not to report any error.
Replace more than 30 ad-hoc error messages with a single, generic one
that contains the name of the option being processed and some hints
to help the user understand what could have gone wrong.

When parsing a cpulist, the virBitmapParse is used. On an invalid
bitmap an error is reported, but the error gets cleared
immediately by subsequent public APIs call, e.g. virDomainFree().
Moreover, we don't check whether bitmap fits into maximal CPU ID
on the host. Therefore the following examples failed without any
error:
# virsh vcpupin test3 1 aaa
# virsh vcpupin test3 1 1000

The --maximum option wasn't properly parsed and the equivalent flag
wasn't set. Fix this bug and also rewrite the way we check this option
by using new macro. The new approach is that --maximum requires
--config, no other combination is allowed, because they don't make sense.
The new error will be:
# virsh setvcpus test --maximum 10
error: Option --config is required by option --maximum

virDomainGetJobStats is able to report statistics of a completed
migration, however to get usable downtime and total time statistics both
hosts have to keep synchronized time. To provide at least some
estimation of the times even when NTP daemons are not running on both
hosts we can just ignore the time needed to transfer a migration cookie
to the destination host. The result will be also inaccurate but a bit
more predictable. The total/down time will just be at least what we
report.

Commit a0670ae caused a regression in 'virsh event' and
'virsh qemu-monitor-event' - if a user tries to filter the
command to a specific domain, an error message is printed:
$ virsh event dom --loop
error: internal error: virsh qemu-monitor-event: no domain VSH_OT_DATA option
and then the command continues as though no domain had been
supplied (giving events for ALL domains, instead of the
requested one). This is because the code was incorrectly
assuming that all "domain" options would be supplied via a
mandatory VSH_OT_DATA, even though "domain" is optional for
these two commands, so we had changed them to VSH_OT_STRING
to quit failing for other reasons (ever since it was decided
that VSH_OT_DATA and VSH_OT_STRING should no longer be
synonyms).
In looking at the situation, though, the code for looking up
a domain was making a pointless check for whether the option
exists prior to finding the option's string value, as
vshCommandOptStringReq does just fine at reporting any errors
when looking up a string whether or not the option was present.
So this is a case of regression fixing by pure code deletion :)

The command did not modify the disk type and thus didn't allow to change
media from a file image to a block backed image or vice versa. In
addition when operating on a network backed removable devices the
command would replace the while <source> subelement with an invalid one.
This patch adds the --block option that allows to specify that the new
image is block backed and assumes that without that option all images
are file backed. Since network backends were always mangled it should
not cause problems.
