57868d121b virsh: support single quote
Some users may type command like this at the virsh shell:
virsh # somecmd 'some arg'

because they often use single quote in linux shell.

a2943243c4 virsh: rework command parsing
Old virsh command parsing mashes all the args back into a string and
miss the quotes, this patches fix it. It is also needed for introducing
qemu-monitor-command which is very useful.

This patches uses the new vshCommandParser abstraction and adds
vshCommandArgvParse() for arguments vector, so we don't need
to mash arguments vector into a command sting.

And the usage was changed:
old:
virsh [options] [commands]

new:
virsh [options]... [<command_string>]
virsh [options]... <command> [args...]

So we still support commands like:
"define D.xml; dumpxml D" was parsed as a commands-string.

and support commands like:
we will not mash them into a string, we use new argv parser for it.

But we don't support the command like:
"define D.xml; dumpxml" was parsed as a command-name, but we have no such command-name.

4417f08de4 virsh: better handling the boolean option
in old code the following commands are equivalent:
     virsh # dumpxml --update-cpu=vm1
     virsh # dumpxml --update-cpu vm1
because the old code split the option argument into 2 parts:
--update-cpu=vm1 is split into update-cpu and vm1,
and update-cpu is a boolean option, so the parser takes vm1 as another
argument, very strange.

after this patch applied, the first one will become illegal.

To achieve this, we don't parse/check options when parsing command sting,
but check options when parsing a command argument. And the argument is
not split when parsing command sting.

ad2f1b6093 virsh: better support double quote
In origin code, double quote is only allowed at the begin or end
"complicated argument"
--some_opt="complicated string"  (we split this argument into 2 parts,
option and data, the data is "complicated string").

This patch makes it allow double quote at any position of
an argument:
complicated" argument"
complicated" "argument
--"some opt=complicated string"

This patch is also needed for the following patches,
the following patches will not split option argument into 2 parts,
so we have to allow double quote at any position of an argument.

a5c646a770 Implement support for virtio plan9fs filesystem passthrough in QEMU
Make use of the existing <filesystem> element to support plan9fs
filesystem passthrough in the QEMU driver

    <filesystem type='mount'>
      <source dir='/export/to/guest'/>
      <target dir='/import/from/host'/>
    </filesystem>

NB, the target is not actually a directory, it is merely a arbitrary
string tag that is exported to the guest as a hint for where to mount
it.

093973aabe xen: Fix virDomain{At,De}tachDevice
According to API documentation virDomain{At,De}tachDevice calls are
supposed to only work on active guests for device hotplug. For anything
beyond that, their *Flags variants have to be used.

Despite the variant which was acked on libvirt mailing list
(https://www.redhat.com/archives/libvir-list/2010-January/msg00385.html)
commit ed9c14a7ef (by Jim Fehlig)
introduced automagic behavior of these API calls for xen driver. Since
January, these calls always change persistent configuration of a guest
and if the guest is currently active, they also hot(un)plug the device.

That change didn't follow API documentation and also broke device
hot(un)plug for older xend implementations which do not support changing
persistent configuration of a guest and hot(un)plugging in one step.

This patch should not break anything for active guests. On the other
hand, changing inactive guests is not supported any more.

which is pretty confusing since no-one requested to modify persistent
config.
