5870f95a7a qemu: Add dump completed event to the capabilities
Add the DUMP_COMPLETED check to the capabilities. This is the
mechanism used to determine whether the dump-guest-memory command
can support the "-detach" option and thus be able to wait on the
event and allow for a query of the progress of the dump.

9c27e464e3 vbox: fix SEGV during dumpxml of a serial port
commit 77a12987a4 changed the "virDomainChrSourceDef source" inside
virDomainChrDef to "virDomainChrSourceDefPtr source", and started
allocating source inside virDomainChrDefNew(), but vboxDumpSerial()
was allocating a virDomainChrDef with a simple VIR_ALLOC() (i.e. never
calling virDomainChrDefNew()), so source was never initialized,
leading to a SEGV any time a serial port was present. The same problem
was created in vboxDumpParallel().

This patch changes vboxDumpSerial() and vboxDumpParallel() to use
virDomainChrDefNew() instead of VIR_ALLOC(), and changes both of those
functions to return an error if virDomainChrDef() (or any other
allocation) fails.

This resolves: https://bugzilla.redhat.com/1536649

5866f48673 nwfilter: Remove unnecessary UUID comparison bypass
Remove the unnecessary check as since commit id '46a811db07' it is
not possible to add or alter a filter using the same name, but with
a different UUID.

NB: It's not required to provide a UUID for a filter by name, but
if one is provided, then it must match the existing. If not provided,
then one is generated during ParseXML processing.

4d83a6722f qemuDomainRemoveMemoryDevice: unlink() memory backing file
https://bugzilla.redhat.com/show_bug.cgi?id=1461214

Since fec8f9c49a we try to use predictable file names for
'memory-backend-file' objects. But that made us provide full path
to qemu when hot plugging the object while previously we provided
merely a directory. But this makes qemu behave differently. If
qemu sees a path terminated with a directory it calls mkstemp()
and unlinks the file immediately. But if it sees full path it
just calls open(path, O_CREAT ..); and never unlinks the file.
Therefore it's up to libvirt to unlink the file and not leave it
behind.

93db7eea1b qemu: migration: Refresh device information after transferring state
In my first approach in 4b480d1076 I overlooked the comment in
qemuMigrationRunIncoming stating that during actual migration the
qemuMigrationRunIncoming does not wait until the migration is complete
but rather offloads that to the Finish phase of migration.

This means that during actual migration qemuProcessRefreshState was
called prior to qemu actually transferring the full state and thus the
queries did not get the correct information. The approach worked only
for restore, where we wait for the migration to finish during qemu
startup.

Fix the issue by calling qemuProcessRefreshState both from
qemuProcessStart if there's no incomming migration and from
qemuMigrationFinish so that the code actually works as expected.

038eb472a0 qemu: Expose rx/tx_queue_size in qemu.conf too
In 2074ef6cd4 and c56cdf259 (and friends) we've added two
attributes to virtio NICs: rx_queue_size and tx_queue_size.
However, sysadmins might want to set these on per-host basis but
don't necessarily have an access to domain XML (e.g. because they
are generated by some other app). So let's expose them under
qemu.conf (the settings from domain XML still take precedence as
they are more specific ones).
