This series adds support for the QEMU iothread poll-weight property,
which controls the weight of the most recent event interval in the
adaptive polling duration calculation. The valid range is [0, 63];
a value of 0 lets QEMU use its default weight.
The series is split by layer:
1) conf/schema support
2) qemu capability detection
3) qemu backend support + public API constants + xmlconf tests
4) virsh support + test driver + virshtest
5) docs: fix pre-existing typos in iothread poll element description
6) docs: formatdomain documentation for poll-weight
The series was validated with:
meson test -C build virschematest
meson test -C build qemucapabilitiestest
meson test -C build qemuxmlconftest
meson test -C build virshtest
meson test -C build genericxml2xmltest
