This checks that the discard on mirror source that effectively zeroes
data is also reflected by the data of target.

This patch adds tests for sync modes top and none.  Test for 'TOP'
is separated out as it requires a backing file.  Also added a test
for invalid format.

Add a test for each of report/ignore/stop.  The tests use blkdebug
to generate an error in the middle of a script.  The error is
recoverable (once = "on") so that we can test resuming a job after
stopping for an error.

These check that a paused streaming job does not advance its offset.

Sometimes the new test fails; the map is different between the source
and the destination of the streaming because qemu-io does not always
pack adjacent clusters that have the same allocated/unallocated state.
However, this also happens with the existing test_stream testcase, and
is better fixed in qemu-io.

This new test case checks that streaming completes successfully when the
backing file is smaller than the image file.

Add tests to exercise the InvalidParameter 'speed' error code path, as
well as the regular success case for setting the speed.  The
block-stream 'speed' parameter allows the speed limit of the job to be
applied immediately when the job starts instead of issuing a separate
block-job-set-speed command later.  If the parameter has an invalid
value we expect to get an error and the job is not created.

It turns out that cancelling a block job is a common operation in these
test cases, let's extract a cancel_and_wait() function instead of
duplicating the QMP commands.

This patch adds a test suite for the image streaming feature.  It
exercises the 'block_stream', 'block_job_cancel', 'block_job_set_speed',
and 'query-block-jobs' QMP commands.
