cc9c62fef9 Require spaces around equality comparisons
Commit a1cbe4b5 added a check for spaces around assignments and this
patch extends it to checks for spaces around '=='.  One exception is
virAssertCmpInt where comma after '==' is acceptable (since it is a
macro and '==' is its argument).

e53b06246c virsh: Honour -q in domblklist, vcpupin and emulatorpin
If user wants to grep some info from domain, e.g. disk paths:

    # virsh -q domblklist win7 | awk '{print $2}'
    Source

    /var/lib/libvirt/images/windows.qcow2
    /home/zippy/work/tmp/en_windows_7_professional_x64_dvd_X15-65805.iso

while with my change:

    # virsh -q domblklist win7 | awk '{print $2}'
    /var/lib/libvirt/images/windows.qcow2
    /home/zippy/work/tmp/en_windows_7_professional_x64_dvd_X15-65805.iso

We don't print table header in other commands, like list.

466b12ab79 virsh: use more compact VIR_ENUM_IMPL
Dan Berrange suggested that using VIR_ENUM_IMPL is more compact
than open-coding switch statements, and still just as forceful
at making us remember to update lists if we add enum values
in the future.  Make this change throughout virsh.

Sure enough, doing this change caught that we missed at least
VIR_STORAGE_VOL_NETDIR.

* tools/virsh-domain-monitor.c (vshDomainIOErrorToString)
(vshDomainControlStateToString, vshDomainStateToString)
(vshDomainStateReasonToString): Change switch to enum lookup.
(cmdDomControl, cmdDominfo): Update caller.
* tools/virsh-domain.c (vshDomainVcpuStateToString)
(vshDomainEventToString, vshDomainEventDetailToString): Change
switch to enum lookup.
(vshDomainBlockJobToString, vshDomainJobToString): New functions.

callers.
* tools/virsh-network.c (vshNetworkEventToString): Change switch
to enum lookup.

0bd2ccdecc Widening API change - accept empty path for virDomainBlockStats
And provide domain summary stat in that case, for lxc backend.
Use case is a container inheriting all devices from the host,
e.g. when doing application containerization.

bb22de2e3e Fix possible memory leak in virsh-domain-monitor.c in cmdDomblklist
In a "for" loop there are created two new strings and they may not
be freed if a "target" string cannot be obtained. We have to free
the two created strings to prevent the memory leak.

This has been found by coverity.

John also pointed out that we should somehow care about the "type"
and "device" and Osier agreed to exit with error message if one of
them is set to NULL.

63d261f395 Rename VIR_DOMAIN_PAUSED_GUEST_PANICKED to VIR_DOMAIN_PAUSED_CRASHED
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

8c20d3f8e7 Remove VIR_DOMAIN_SHUTDOWN_CRASHED from public API
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

places where the specification of .flags parameter differed.  After
going through many options and deciding whether to unify the
initialization to be '.flags = 0' or '.flags = VSH_OFLAG_NONE', I
realized both can be removed and it makes the code easier to go
through.

5f75bd4bbe snapshot: Add flag to enable creating checkpoints in live state
The default behavior while creating external checkpoints is to pause the

space saving for creating the memory save image while the guest is live
to minimize downtime.

This patch adds a flag that causes the guest not to be paused before
taking the snapshot.
