2ef091efcc python: Fix networkLookupByUUID
According to:

http://libvirt.org/html/libvirt-libvirt.html#virNetworkLookupByUUID

virNetworkLookupByUUID() expects a virConnectPtr as its first argument,
thus making it a method of the virConnect Python class.

Currently it's a method of libvirt.virNetwork.

0c842417ef Allow suspend during live migration
Currently no command can be sent to a qemu process while another job is
active. This patch adds support for signaling long-running jobs (such as
migration) so that other threads may request predefined operations to be
done during such jobs. Two signals are defined so far:
    - QEMU_JOB_SIGNAL_CANCEL
    - QEMU_JOB_SIGNAL_SUSPEND

The first one is used by qemuDomainAbortJob.

The second one is used by qemudDomainSuspend for suspending a domain
during migration, which allows for changing live migration into offline
migration. However, there is a small issue in the way qemudDomainSuspend
is currently implemented for migrating domains. The API calls returns
immediately after signaling migration job which means it is asynchronous
in this specific case.

be7780b035 do not require two ./autogen.sh runs to permit "make"
* autogen.sh (bootstrap_hash): New function.
Running bootstrap may update the gnulib SHA1, yet we were computing
t=$(git submodule status ...) *prior* to running bootstrap, and
then recording that sometimes-stale value in the stamp file upon
a successful bootstrap run.  That would require two (lengthy!)
bootstrap runs to update the stamp file.

83988bd43b Make nodeGetInfo report the correct number of NUMA nodes.
The nodeGetInfo code was always assuming that machine had a
single NUMA node, which is not correct.  The good news is that
libnuma gives us this information pretty easily, so let's
properly report it.

NOTE: With recent hardware starting to support CPU hot-add
and hot-remove, both this code and the nodeCapsInitNUMA()
code are quickly going to become obsolete.  We'll have to
think of a more dynamic solution for dealing with NUMA
nodes and CPUs that can come and go at will.

3ebbc241a1 Fix crash in virsh after bogus command
If you ran virsh in interactive mode and ran a command
that virsh could not parse, it would then SEGV
on subsequent commands.  The problem is that we are
freeing the vshCmd structure in the syntaxError label
at the end of vshCommandParse, but forgetting to
set ctl->cmd to NULL.  This means that on the next command,
we would try to free the same structure again, leading
to badness.

  freeing it in vshCommandParse()

d376b7d63e Fix hang in qemudDomainCoreDump.
Currently if you dump the core of a qemu guest with
qemudDomainCoreDump, subsequent commands will hang
up libvirtd.  This is because qemudDomainCoreDump
uses qemuDomainWaitForMigrationComplete, which expects
the qemuDriverLock to be held when it's called.  This
patch does the simple thing and moves the qemuDriveUnlock
to the end of the qemudDomainCoreDump so that the driver
lock is held for the entirety of the call (as it is done
in qemudDomainSave).  We will probably want to make the
lock more fine-grained than that in the future, but
we can fix both qemudDomainCoreDump and qemudDomainSave
at the same time.

2c555d87b0 Make sure qemudDomainSetVcpus doesn't hang.
The code to add job support into libvirtd caused a problem
in qemudDomainSetVcpus.  In particular, a qemuDomainObjEndJob()
call was added at the end of the function, but a
corresponding qemuDomainObjBeginJob() was not.  Additionally,
a call to qemuDomainObj{Enter,Exit}Monitor() was also missed
in qemudDomainHotplugVcpus().  These missing calls conspired to
cause a hang in the libvirtd process after the command was
finished.  Fix this by adding the missing calls.

8a7f4b8dc1 Remove qemudDomainSetMaxMemory.
As previously discussed[1], this patch removes the
qemudDomainSetMaxMemory() function, since it doesn't
work.  This means that instead of getting somewhat
cryptic errors, you will now get:

error: Unable to change MaxMemorySize
error: this function is not supported by the hypervisor: virDomainSetMaxMemory

Which describes the situation perfectly.

ed3d86c9a9 Fix a JSON CPU information bug.
When using the JSON monitor, qemuMonitorJSONExtractCPUInfo
was returning 0 on success.  Unfortunately, higher levels of
the cpuinfo code expect that it returns the number of CPUs
it found on success.  This one-line patch fixes it so that
it returns the correct number.  This makes "virsh vcpuinfo <domain>"
work when using the JSON monitor.

7be9270c24 Fix up nodeinfo parsing code.
As pointed out by eblake, I made a real hash of the
nodeinfo code with commit
aa2f6f96dd.  This patch
cleans it up:

1)  Do more work at compile time instead of runtime (minor)
2)  Properly handle the hex digits that come from
/sys/devices/system/cpu/cpu*/topology/thread_siblings
3)  Fix up some error paths that could cause SEGV
4)  Used unsigned's for the cpu numbers (cpu -1 doesn't
make any sense)

Along with the recent patch from jdenemar to zero out
the nodeinfo structure, I've re-tested this on the
machines having the problems, and it seems to be good.
