148cfcf051 qemu: Pass / fill niothreads for qemuMonitorGetIOThreads
Let's pass along / fill @niothreads rather than trying to make dual
use as a return value and thread count.

This resolves a Coverity issue detected in qemuDomainGetIOThreadsMon
where if qemuDomainObjExitMonitor failed, then a -1 was returned and
overwrite @niothreads causing a memory leak.

947d2db31b Use virHashForEachSorted in tested code
The simplest way to write tests is to check the output against expected
output, but we must ensure that the output is stable. We can use
virHashForEachSorted as a hash iterator to ensure stable ordering.

This patch fixes 3 instances of hash iteration which is tested in
various parts, including test output changes in appropriate places.

1c2314b938 qemu: Update to new design of 'block-export-add'
qemu decided to modify the arguments of 'block-export-add' to include an
array of bitmaps rather than a single bitmap.

Since we've added the code prior to qemu setting the interface in stone
and thus it will be changed incompatibly and we already have tests for
the new interface we need to update the code and qemu capabilities data
at the same time.

Use a array of bitmaps as the 'bitmaps' argument instead of 'bitmap' and
bump qemu capabilities for the upcoming 5.2.0 release to
v5.1.0-2827-g2c6605389c
