7eb13c9daa qemu-iotests: Test the 'base-node' parameter of 'block-stream'
The block-stream command has traditionally used the 'base' parameter
to indicate the image to copy the data from. This test checks that the
'base-node' parameter can also be used for the same purpose.

48361afba9 qemu-iotests: Test streaming to a Quorum child
Quorum children are special in the sense that they're not directly
attached to a block backend but they're not used as backing images
either. However the intermediate block streaming code supports
streaming to them. This is a test case for that scenario.

704d59f13d qemu-iotests: Test block-stream and block-commit in parallel
As with test_stream_parallel(), we allow mixing block-stream and
block-commit operations in the same backing chain as long as there's
no overlap among the involved nodes.

eb290b78ff qemu-iotests: Test overlapping stream and commit operations
These test cases check that it's not possible to perform two
block-stream or block-commit operations if there are nodes involved in
both.

c1a34322d8 qemu-iotests: Test block-stream operations in parallel
This test case checks that it's possible to launch several stream
operations in parallel in the same snapshot chain, each one involving
a different set of nodes.

This adds test_stream_intermediate(), similar to test_stream() but
streams to the intermediate image instead.

409d54986d qemu-iotests: add no-op streaming test
This patch tests that in a partial block-stream operation, no data is
ever copied from the base image.

90f0b71153 qemu-iotests: add tests for streaming error handling
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.

0c81734765 qemu-iotests: add test for pausing a streaming operation
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.

e425306a27 qemu-iotests: add block-stream speed value test case
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.
