qmp: add block_stream command
Add the block_stream command, which starts copy backing file contents into the image file. Also add the BLOCK_JOB_COMPLETED QMP event which is emitted when image streaming completes. Later patches add control over the background copy speed, cancelation, and querying running streaming operations.
