If block job is completed with error qemu additionally
provides error message. This patch introduces new event
VIR_DOMAIN_EVENT_ID_BLOCK_JOB_ERROR to pass error message to client.
This error message has no semantics and should not be interpreted.
API and RPC layer also have reserved 'code' field to pass semantics
loaded error code value in the future.
---
The patch is applied on top of [1] patch series (not yet pushed though).
Diff from v1 [2]:
1. Replace block job event version 3 with block job error event.
2. Add code field to API/RPC to pass error code in the future.
Peter, I decided not to use enum/union as this looks like to much effort to extend
code generation for this simple case. Using typed params looks unsuitable too.
