Commit abfff210 changed the order of vshParseArgv() and vshInit() in
order to make fix debugging of parameter parsing. However, vshInit()
did a vshReconnect() even though ctl->name wasn't set according to the
'-c' parameter yet. In order to keep both issues fixed, I've split
the vshInit() into vshInitDebug() and vshInit().
One simple memleak of ctl->name is fixed as a part of this patch,
since it is related to the issue it's fixing.

Use the new semantics of vshStringToArray to avoid leaking the array of
volumes to be deleted. The array would be leaked in case the first
volume was found in the domain definition. Also refactor the code a bit
to sanitize naming of variables hoding arrays and dimensions of the
arrays.

At a slightly larger memory expense allow stealing of items from the
string array returned from vshStringToArray and turn the result into a
string list compatible with virStringSplit. This will allow to use the
common dealloc function.
This patch also fixes a few forgotten checks of return from
vshStringToArray and one memory leak.

Currently the virConnectBaselineCPU API does not expose the CPU features
that are part of the CPU's model. This patch adds a new flag,
VIR_CONNECT_BASELINE_CPU_EXPAND_FEATURES, that causes the API to explicitly
list all features that are part of that model.

The virLoginShellAllowedUser method must not free the 'groups'
parameter it is given, as that is owned by the caller.
The virLoginShellAllowedUser method should be checking
'!*ptr' (ie empty string) rather than '!ptr' (NULL string)
since the latter cannot be true.

The VIR_DOMAIN_PAUSED_GUEST_PANICKED constant is badly named,
leaking the QEMU event name. Elsewhere in the API we use
'CRASHED' rather than 'PANICKED', and the addition of 'GUEST'
is redundant since all events are guest related.
Thus rename it to VIR_DOMAIN_PAUSED_CRASHED, which matches
with VIR_DOMAIN_RUNNING_CRASHED and VIR_DOMAIN_EVENT_CRASHED.
It was added in commit 14e7e0ae8d
which post-dates v1.1.0, so is safe to rename before 1.1.1

The VIR_DOMAIN_SHUTDOWN_CRASHED state constant does not appear
to be used in the QEMU code anyway. It also doesn't make much
(any) sense, since the 'shutdown' state is a transient state
between 'running' and 'shutoff' and when a guest crashes, it
does not end up in a 'shutdown' state, only 'shutoff'.
It was added in commit 14e7e0ae8d
which post-dates v1.1.0, so is safe to remove before 1.1.1

Noticed that the expected "not supported" error is dropped when
invoking 'virsh snapshot-list dom' on a Xen installation running
the libxl driver
virsh snapshot-list test
error: Invalid snapshot: virDomainSnapshotFree
The error is overwritten by a call to virDomainSnapshotFree
in cleanup code within cmdSnapshotList. Prevent overwritting
the real error by not calling virDomainSnapshotFree with a NULL
virDomainSnapshotPtr.

When cdrom is block type, the virsh change-media failed to insert
source info because virsh uses "<source block='/dev/sdb'/>" while
the correct name of the attribute for block disks is "dev".
Add a "--pass-fds N,M,..." arg to the virsh start/create
methods. This allows pre-opened file descriptors from the

Paolo Bonzini pointed out that it's actually possible to migrate a qemu
instance that was paused due to I/O error and it will be able to work on
the destination if the storage is accessible.
This patch introduces flag VIR_MIGRATE_ABORT_ON_ERROR that cancels the
migration in case an I/O error happens while it's being performed and
allows migration without this flag. This flag can be possibly used for
other error reasons that may be introduced in the future.
This patch fixes changes done in commit 29c1e913e4
that was pushed without implementing review feedback.
The flag introduced by the patch is changed to VIR_DOMAIN_VCPU_GUEST and
documentation makes the difference between regular hotplug and this new
functionality more explicit.
The virsh options that enable the use of the new flag are changed to
"--guest" and the documentation is fixed too.
This flag will allow to use qemu guest agent commands to disable
(offline) and enable (online) processors in a live guest that has the
guest agent running.
