This update for qemu fixes the following issues:

qemu was updated to v3.1.1.1, a stable, bug-fix-only release, which
includes 2 fixes we already carry, as well as one additional use-
after-free fix in slirp. (CVE-2018-20126 bsc#1119991,
CVE-2019-14378 bsc#1143794, and CVE-2019-15890 bsc#1149811
respectively)

Security issues fixed:

- CVE-2019-12068: Fixed potential DOS in lsi scsi controller emulation (bsc#1146873)
- CVE-2019-11135: Expose taa-no "feature", indicating CPU does not have the TSX Async Abort vulnerability. (bsc#1152506)
- CVE-2018-12207: Expose pschange-mc-no "feature", indicating CPU does not have the page size change machine check vulnerability (bsc#1117665)

Other issues fixed:

- Change how this bug gets fixed (bsc#1144087)

issues with PV domUs during migration. The issues triggered by
the locking can not be properly handled in libxl. The locking
introduced in qemu-2.10 was removed again in qemu-4.0.
