[PATCH v3 0/4] handle error in feature testing

[Nikolay Shirokovskiy]

Justification is in the last patch.

Diff to v2 [1]:
- instead of RFC where fix was applied only to virMigrate3 now
  all the places where VIR_DRV_SUPPORTS_FEATURE is used patched
  to handle errors


[1] [RFC PATCH v2] fix error message in virMigrate3 if connection is broken
https://www.redhat.com/archives/libvir-list/2020-September/msg01348.html

Nikolay Shirokovskiy (4):
  src: adopt to VIR_DRV_SUPPORTS_FEATURE return -1
  libxl: adopt to VIR_DRV_SUPPORTS_FEATURE return -1
  qemu: adopt to VIR_DRV_SUPPORTS_FEATURE return -1
  src: don't hide error in VIR_DRV_SUPPORTS_FEATURE
