8fe09a5317 virsh: fixing segfault by pool autocompleter function.
The commands which requires a pool to perform any action for a volume is
throwing a segfault when you pass the volume name before a pool name or
without the argument '--pool'.

An example that works:
virsh # vol-list loops-pool
 Name                 Path
-------------------------------------------------------------------
 loop0                /mnt/loop0

virsh # vol-info --pool loops-pool lo<TAB>

An example that does not work:
virsh # vol-list loops-pool
 Name                 Path
-------------------------------------------------------------------
 loop0                /mnt/loop0

virsh # vol-info lo<TAB>
Segmentation Fault

The example 'vol-info' can be executed as 'vol-info loop0 --pool
loops-pool'. So, this commit fixes this problem when the arguments are
inverted and avoids the segfault.

1297db7414 nwfilter: save error from DHCP snoop thread to report in main thread
A problem encountered due to a bug in libpcap was reported to the
caller as:

   An error occurred, but the cause is unknown

This was because the error had been logged in the DHCPSnoop
thread. The worker thread handling the API call to start a domain
spins up the DHCPSnoop thread which watches for dhcp packets with
libpcap, then uses virCondSignal() to notify the worker thread (which
has been waiting with virCondWait()). The worker thread knows that
there was an error (because threadStatus != THREAD_STATUS_OK), but the
error info had been stored in thread-specific storage for the other
thread, so the worker thread can only report that there was a failure,
but it doesn't know why.

The solution is to save the error that was logged (with
virErrorPreserveLast() into the object the is used to share info
between the threads, then we can set the error in the worker thread
using virErrorRestore().

In the case of the error I was looking at, this changed the "unknown"
message into:

    internal error: pcap_setfilter: can't remove kernel filter:
    Bad file descriptor

e1ab81b339 storage: fix sheepdog driver / test linking to avoid duplicating source
The libvirt_storage_backend_sheepdog_priv.la library depends on symbols
provided in the libvirt_driver_storage_impl.la library. As such the
latter must be listed 2nd when passed to the linker to avoid symbol
resolution problems. This mistake is being masked by the sheepdog
driver linking in a second copy of the storage driver code. Remove
this duplicate linkage of backend source and fix the test link order.

19d3d2633c make: fix uninstall of subdirectory data
A typo in the uninstall-data-extra rule expansion meant we just called
the install rule again, instead of the uninstall rule. While fixing
this, just inline the dependancy, since the intermediate
install-data-extra rule adds no value.

9ea69808f5 qemu: Add virConnectPtr back to some migration methods
This partially reverts 82592551cb.

When migrating a domain, qemuMigrationDstPrepareAny() is called
which eventually calls qemuProcessLaunch(conn = NULL, flags =
VIR_QEMU_PROCESS_START_AUTODESTROY); But the very first thing
that qemuProcessLaunch does is check if AUTODESTROY flag is set
and @conn is not NULL. Well, it is.

ff02d1af40 tools: avoid text spilling into variables
While libvirt-guests.sh is running cases can let guest_is_on fail which
causes check_guests_shutdown to print output.
That output shall not spill into the users of function
check_guests_shutdown which is therefore now returning values in a
variable like guest_is_on already did.

edae027cfe qemu: Fix updating device with boot order
Commit v3.7.0-14-gc57f3fd2f8 prevented adding a <boot order='x'/>
element to an inactive domain with global <boot dev='...'/> element.
However, as a result of that change updating any device with boot order
would fail with 'boot order X is already used by another device', where
"another device" is in fact the device which is being updated.

To fix this we have to ignore the device which we're about to update
when checking for boot order conflicts.

b6a264e855 Pass oldDev to virDomainDefCompatibleDevice on device update
When calling virDomainDefCompatibleDevice to check a new device during
device update, we need to pass the original device which is going to be
updated in addition to the new device. Otherwise, the function can
report false conflicts.

The new argument is currently ignored by virDomainDefCompatibleDevice,
but this will change in the following patch.
