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:

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 :)

Signed-off-by: Luyao Huang <lhuang@redhat.com>
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.
Since cmdDetachDisk() calls into vshPrepareDiskXML() with
type == VSH_PREPARE_DISK_XML_NONE && source == NULL this would result
into skipping all the checks and effectively turn the function into a
XML formatter.
This patch changes the code to use the formatter directly so that the
function can be refactored in a easier way.
Commit f182da20 (v1.2.6) caused a slight regression in virsh

virsh's domdisplay command looks in /domain/devices/graphics/@listen
of the domain's XML for the listen address, however for listen
type='network' (added in libvirt 0.9.4), the <graphics> element
doesn't have a listen attribute, but has a <listen> subelement,
*still* with no address (this is the inactive XML):
<graphics type='spice' autoport='yes' keymap='en-us'>
<listen type='network' network='default'/>
</graphics>
However, at domain start time the <listen> subelement gets its address
attribute filled in once libvirt figures out the IP address associated
with the named network (this is the status XML):
<graphics type='spice' port='5901' autoport='yes' keymap='en-us'>
<listen type='network' address='192.168.122.1' network='default'/>
</graphics>
So in these cases, we need to look at
/domain/devices/graphics/listen/@address instead.
Even though another patch is being pushed that will backfill
listen/@address into @listen, this patch is still useful, as it fixes
domdisplay for cases of a new virsh (with this patch) connecting to a
libvirtd that is newer than 0.9.4 but doesn't have the followup patch.

The 'virsh edit' command gets XML validation enabled by default,
with a --skip-validate option to disable it. The 'virsh define'
and 'virsh create' commands get a --validate option to enable
it, to avoid regressions for existing scripts.
The quality of error reporting from libxml2 varies depending
on the type of XML error made. Sometimes it is quite clear
and useful, other times it is obscure & inaccurate. At least
the user will see an error now, rather than having their
XML modification silently disappear.

When a block{pull, copy, commit} is aborted via keyboard interrupt,
the job is properly canceled followed by proper error message.
However, when the job receives an abort from another client connected
to the same domain, the error message incorrectly indicates that
a blockjob has been finished successfully, though the abort request
took effect. This patch introduces a new blockjob abort handler, which
is registered when the client calls block{copy,commit,pull} routine,
providing its caller the status of the finished blockjob.
