In a constrained CI environment, where it is intentional that attempts
to write outside the current directory will fail, virsh-snapshot was
failing:

error: invalid argument: parent s3 for snapshot s2 not found
error: marker
+error: Failed to create '/home/travis/.cache/libvirt/virsh': Permission denied
FAIL virsh-snapshot (exit status: 1)
But we've already solved the problem in virsh-uriprecedence: tell
virsh to use XDG locations pointing to somewhere we can write rather
than its default of falling back to $HOME with the test being at risk
of breaking due to the user's environment and/or unacceptably altering
the user's normal cache. Hoist that solution into test-lib.sh, so
that all scripts can use it as needed. While at it, fix a latent typo
where XDG_RUNTIME_HOME was set to a literal relative directory name
"XDG_CACHE_HOME" (the typo did not affect virsh-uriprecedence, but
could matter to other clients).

There are a few differences, but the one we're interested in is
that PCIe Root Ports are finally available: as a result of this,

The rules are the same for all virt guests, regardless of the

Our PCIe topology depends on the availability of PCIe Root Ports,
so if none of the suitable devices (pcie-root-port, ioh3420) is
compiled into QEMU we should fall back to virtio-mmio rather than
trying to use PCI addresses only to fail immediately afterwards
when we realize we can't use the necessary controllers.
Note that this additional check is basically moot for ARM virt
guests, because PCIe Root Ports were enabled in QEMU builds for
the architecture well before guest OS support had been widely
available; however, the opposite is true for RISC-V, and tweaking
the code this way will allow us to share it between architectures.

If the console was disconnected due to a connection problem or a problem on the
server side it is convinient to provide the cause to the user. If the error
come from the API then the error is saved in a virsh global variable. However,
since success is returned from virshRunConsole after we reach the waiting stage,
then the error is never reported. Let's track the error in the event loop.
Next after failure we do a cleanup and this cleanup can overwrite
root cause. Thus let's save root cause immediately and then set it to
virsh error after all cleanup is done.
Since we'll be sending the error to the consumer, each failure path from
the event handlers needs to be augmented to provide what error generated
the failure.

On error in main thread virConsoleShutdown is called which

If there are two concurrent threads, one of which is removing an
nwfilter from the list and the other is trying to add it back they
may serialize in the following order:
1) obj->removing is set and @obj is unlocked.
2) The tread that's trying to add the nwfilter onto the list locks
the list and tries to find, if the nwfilter already exists.
3) Our lookup functions say it doesn't, so the thread proceeds to
virHashAddEntry() which fails with 'Duplicate key' error.
This is obviously not helpful error message at all.
The problem lies in our lookup function
(virNWFilterBindingObjListFindByPortDevLocked()) which return
NULL even if the object is still on the list. They do this so
that the object is not mistakenly looked up by some API. The fix
consists of moving 'removing' check one level up and thus
allowing virNWFilterBindingObjListAddLocked() to produce
meaningful error message.
