Merge remote-tracking branch 'remotes/bonzini/tags/for-upstream' into staging

Mostly bugfixes, plus a patch to mark accelerator MemoryRegions in "info
mtree" that has been lingering for too long.

* remotes/bonzini/tags/for-upstream:
  target/i386: sev: fix failed message typos
  i386: indicate that 'pconfig' feature was removed intentionally
  build-sys: do no support modules on Windows
  qmp: don't emit the RESET event on wakeup
  hmp: Print if memory section is registered with an accelerator
  test-bitmap: add test for bitmap_set
  scsi-generic: Check sense key before request snooping and patching
  vhost-user-scsi: Call virtio_scsi_common_unrealize() when device realize failed
  vhost-scsi: Call virtio_scsi_common_unrealize() when device realize failed
  virtio-scsi: remove unused argument to virtio_scsi_common_realize
  target/i386: skip KVM_GET/SET_NESTED_STATE if VMX disabled, or for SVM
  target/i386: kvm: Demand nested migration kernel capabilities only when vCPU may have enabled VMX
