d1a7102389 virStringListLength: Ensure const correctness
The virStringListLength function does not ever modify the passed
string list. It merely counts the items in it. Make sure that we
reflect this bit in the function header.

e9394d699c tests: qemuxml2argv: remove some QEMU_CAPS_DEVICE problem cases
When we unconditionally enable QEMU_CAPS_DEVICE, these tests need
some massaging, so do it ahead of time to not mix it in with the
big test refresh.

- minimal-s390 is not a real world working config, so drop it
- disk-usb was testing for an old code path that will be removed.
  instead use it to test lack of USB disk support, and rename it
  to disk-usb-nosupport. Switch xml2xml to use disk-usb-device for
  input.
- cputune-numatune was needlessly using q35, switch it to an older
  machine type

73b70b403d virDomainFormatSchedDef: Initialize @priority
Older gcc fails to see that the variable is set iff @hasPriority
== true in which case the former is set a value. Initialize the
value while declaring it to make the compiler shut up.

d093d623e3 tests: qemuxml2xml: Always use different output file
Most qemuxml2xml tests expect that the input XML is unchanged after
parsing. This is unlike 99% of new qemu configs in the wild, which after
initial parsing end up with stable PCI device addresses. The xml2xml bit
doesn't currently hit that code path though, so most XML testing indeed
does not change.

Future patches will add that PCI address bits, which means most test cases
will have different output. So let's do away with the hardcoded same vs
different test split, and always track a separate output file. Tests can
still have same input and output, it just necessitates 2 separate XML files.

d498a89950 Fix '-pie' build with clang
Commit 97e70a5935 added the option -pie to
CFLAGS and LDFLAGS, however '-pie' is just a linker option.  That
wouldn't be a problem.  However, clang is checking for that and outputs
an error or unused argument:

error: argument unused during compilation: '-pie'

Since majority of the steps is shared, the function can be reused to

Additionally this resolves
https://bugzilla.redhat.com/show_bug.cgi?id=1244128 since the cpu
bandwidth limiting with cgroups would not be set on the hotplug path.

Additionally the code now sets the thread affinity and honors autoCpuset
as in the regular startup code path.

d9c57ca9f9 remote: enforce VIR_TYPED_PARAM_STRING_OKAY flag on client side serialization
Commit 8cd1d54 consolidates both daemon and remote driver typed param
serialization functions. The consolidation now enforces client to use
VIR_TYPED_PARAM_STRING_OKAY flag to properly serialize string parameters, which
server has used for quite some time now. And this caused an issue, since the
commit had not adjusted client remote calls appropriately, thus causing a
failure in blkiotune, numatune and migration APIs (as per Xen CI tests). This
patch adjusts both remote_driver.c and gendispatch.pl to properly address this
issue.

99c5fe0e7c conf: Don't store vcpusched orthogonally to other vcpu info
Due to bad design the vcpu sched element is orthogonal to the way how
the data belongs to the corresponding objects. Now that vcpus are a
struct that allow to store other info too, let's convert the data to the
sane structure.

The helpers for the conversion are made universal so that they can be
reused for iothreads too.

This patch also resolves https://bugzilla.redhat.com/show_bug.cgi?id=1235180
since with the correct storage approach you can't have dangling data.

d0d341a30b qemu: Reuse qemuDomainDetectVcpuPids in cpu hot(un)plug
Now that qemuDomainDetectVcpuPids is able to refresh the vCPU pid
information it can be reused in the hotplug and hotunplug code paths
rather than open-coding a very similar algorithm.

A slight algorithm change is necessary for unplug since the vCPU needs
to be marked offline prior to calling the thread detector function and
eventually rolled back if something fails.

e84ab7938d conf: Move and optimize disk target duplicity checking
Move the logic from virDomainDiskDefDstDuplicates into
virDomainDiskDefCheckDuplicateInfo so that we don't have to loop
multiple times through the array of disks. Since the original function
was called in qemuBuildDriveDevStr, it was actually called for every
single disk which was quite wasteful.

Additionally the target uniqueness check needed to be duplicated in
the disk hotplug case, since the disk was inserted into the domain
definition after the device string was formatted and thus
virDomainDiskDefDstDuplicates didn't do anything in that case.
