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.

db58f9c060 qmp: make block job command naming consistent
The block streaming and job commands used '_' instead of '-' for reasons
of compatibility with libvirt, which already included support for the
'_' naming.  However, the semantics of block_job_cancel have changed and
libvirt now needs to handle the new semantics.

Since the old semantics were never in a QEMU release we can still rename
the commands to use '-' instead of '_'.  Libvirt is also happy because
the new name can be used to distinguish QEMU binaries that support the
latest block-job-cancel semantics from those that include a downstream
block_job_cancel command.

Therefore, let's apply the QAPI/QMP naming rules to the block streaming
and job commands.  QEMU 1.1 will be the first release with these
commands so no upstream users can break.

Note that HMP commands are left with '_' because that is the convention
there.

1042ec94b1 qemu-iotests: Fix test 031 for qcow2 v3 support
qcow2.py must be updated to work with version 3 images at all, the

qemu-io are not well-suited for shell scripting.  This patch adds a

  VM          - class for launching and interacting with a VM
  QMPTestCase - abstract base class for tests that use QMP
  qemu_img()  - wrapper function for invoking qemu-img
  qemu_io()   - wrapper function for invoking qemu-io
  imgfmt      - the image format under test (e.g. qcow2, qed)
  test_dir    - scratch directory path for temporary files

bfe8524862 qemu-iotests: Update filter for default cluster size
Until recently, qemu-img create displayed cluster_size=0 for the default
cluster size. It is changed to display the real cluster size now, which results
in the cluster size not being filtered out any more.

and if using the default, filter it out. This mostly restores the old behaviour
of the test cases; test 015 must be fixed to use CLUSTER_SIZE instead of using
extra_img_options for it.

dd0c35d69b qemu-iotests: Use zero-based offsets for IO patterns
The io_pattern style functions have the following loop:

  for i in `seq 1 $count`; do
      echo ... $(( start + i * step )) ...
  done

Offsets are 1-based so start=1024, step=512, count=4 yields:
1536, 2048, 2560, 3072

Normally we expect:
1024, 1536, 2048, 2560

Most tests ignore this detail, which means that they perform I/O to a
slightly different range than expected by the test author.

Later on things got less innocent and tests started trying to compensate
for the 1-based indexing.  This included negative start values in test
024 and my own attempt with count-1 in test 028!

The end result is that tests that use io_pattern are hard to reason
about and don't work the way you'd expect.  It's time to clean this mess
up.

This patch switches io_pattern to 0-based offsets.  This requires
adjusting the golden outputs since I/O ranges are now shifted and output
differs.

Verifying these output diffs is easy, however.  Each diff hunk moves one
I/O from beyond the end of the pattern range to the beginning.
