df89d11227 qemu-iotests: Allow caller to disable underscore convertion for qmp
QMP command "block_set_io_throttle" expects underscores in parameters
instead of dashes: {iops,bps}_{rd,wr,max}.

Add optional argument conv_keys (defaults to True, backward compatible),
it will be used in IO throttling test case.

79e7a01954 qemu-iotests: Fix supported_oses check
There is a bug in the recently added sys.platform test, and we no longer
run python tests, because "linux2" is the value to compare here. So do a
prefix match. According to python doc [1], the way to use sys.platform
is "unless you want to test for a specific system version, it is
therefore recommended to use the following idiom":

if sys.platform.startswith('freebsd'):
    # FreeBSD-specific code here...
elif sys.platform.startswith('linux'):
    # Linux-specific code here...

bc52169660 qemu-iotests: Add supported os parameter for python tests
If I understand correctly, qemu-iotests never meant to be portable. We
only support Linux for all the shell cases, but didn't specify it for
python tests. Now add this and default all the python tests as Linux
only. If we cares enough later, we can override the parameter in
individual cases.

1d3ba15acc iotests: Omit length/offset test in 040 and 041
As of a follow-up patch to this one, the length of a mirror block job
will no longer directly depend on the size of the block device;
therefore, drop these checks from this test. Instead, just check whether
the final offset equals the block job length.

As 041 uses the wait_until_completed function from iotests.py, the same
applies there as well which in turn affects tests 030, 055 and 056. On
the other hand, a block job's length does not have to be related to the
length of the image file in the first place, so that check was
questionable anyway.

e8f8624d3b iotests: Allow out-of-tree run
As out-of-tree builds are preferred for qemu, running the qemu-iotests
in that out-of-tree build should be supported as well. To do so, a
symbolic link has to be created pointing to the check script in the
source directory. That script will check whether it has been run through
a symlink, and if so, will assume it is run in the build tree. All
output and temporary operations performed by iotests are then redirected
here and, unless specified otherwise by the user, QEMU_PROG etc. will be
set to paths appropriate for the build tree.

Also, drop making every test case executable if it is not yet, as this
would modify the source tree which is not desired for out-of-tree runs
and should be fixed in the repository anyway.

0dbe8a1b04 qemu-iotests: extract wait_until_completed() into iotests.py
The 'drive-mirror' tests often issue 'block-job-complete' and wait for
the QMP completion event.  Other types of block jobs also want to wait
for completion but they may not need to issue 'block-job-complete'.

Extract wait_until_completed() from 041 and put it into iotests.py.
Return the QMP event object so the caller can make additional
assertions, if necessary.

The iotests.compare_images() function returns True if two image files
have the identical data.  Previously this was implemented by converting
images to raw and then comparing their contents using Python.  Since
"qemu-img compare" is now available and is more efficient, switch to it.

This function will be reused by the 'drive-backup' test case.

4f45056841 qemu-iotests: map underscore to dash in QMP argument names
iotests.py provides a convenience function that uses Python keyword
arguments to represent QMP command arguments.  However, almost all
QMP commands use dashes for argument names (the sole exception is
block_set_io_throttle), and dashes are not allowed in a keyword
argument name.  Hence provide automatic conversion of underscores
to dashes.

f345cfd019 qemu-iotests: add iotests Python module
Block layer tests that involve QMP commands rather than qemu-img or
qemu-io are not well-suited for shell scripting.  This patch adds a
Python module which allows tests to be written in Python instead.

The basic API is:

  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
  main()      - entry point for running tests
