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.
