Currently, if a qemu/qemu-io/qemu-img/qemu-nbd invocation receives a
segmentation fault, that message is invisible in most cases since the
output is generally filtered and bash suppresses the segmentation fault
notice for any but the last element of a pipe.
Most of the time, the test will then fail anyway because of missing
output, but not necessarily (as happened with test 82 recently).
Fix this by making the corresponding environment variables point to
wrapper functions which execute the respective command in a subshell.
Giving options to qemu/qemu-io/qemu-img and path names with spaces were
broken for the Python tests; this patch "accidentally" fixes that.

This patch adds qemu machine type support to the io test suite.
Based on the qemu default machine type and alias of the default machine
type the reference output file can now vary from the default to a
machine specific output file if necessary. When using a machine specific
reference file if the default machine has an alias then use the alias as the output
file name otherwise use the default machine name as the output file name.

Adding "-d" option. The output goes to "tee" so it appears in your
console. Also, raise the verbosity of unnitest runner.
When testing a topic branch, it's possible that a bug introduced by a
code change makes the python test case hang, with debug output, it is
much easier to locate the problem.
This can also be helpful if you want to watch the progress of a python
test, it offers you a way to sense the speed of each test case method
you're writing.
Note: because there is no easy way to get *both* the verbose output and
the output expected by ./check comparison, the case would always fail
with an "output mismatch". The sole purpose of using this option is
giving developers a quick way to debug when things go wrong.

Using /tmp, which is usually mounted as tmpfs, the quick group can be
quicker.
On my laptop (Lenovo T430s with Fedora 20), this reduces the time from
50s to 30s.

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.

This reverts commit f915db07ef9c368ea6db6430256de064fdd1525f.
This commit is broken because it does not account for the
build tree and the source tree being different, and can cause
build failures for out-of-tree builds. Revert it until we can
identify a better solution to the problem.

Currently, QEMU's iotests rely on /usr/bin/env to start the correct
Python (that is, at least Python 2.4, but not 3). On systems where
Python 3 is the default, the user has no clean way of making the iotests
use the correct binary.
This commit makes the iotests use the Python selected by configure.

This case can't run when IMGPROTO=nbd, since it needs to create some
internal snapshot which would fail for EOF write request, even when
TEST_IMG is exported with "-f raw" in common.rc, so set _supported_proto
to file.
_require_command() is changed to tip what util is missing, instead
of printing a blank.

The reference output for test case 026 hasn't been updated in a long
time and it's one of the "known failing" cases. This patch updates the
reference output so that unintentional changes can be reliably detected
again.
The problem with this test case is that it produces different output
depending on whether -nocache is used or not. The solution of this patch
is to actually have two different reference outputs. If nnn.out.nocache
exists, it is used as the reference output for -nocache; otherwise,
nnn.out stays valid for both cases.

glibc wipes malloc(3) memory when the MALLOC_PERTURB_ environment
variable is set. The value of the environment variable determines the
bit pattern used to wipe memory. For more information, see
http://udrepper.livejournal.com/11429.html.
Set MALLOC_PERTURB_ for gtester and qemu-iotests. Note we pick a random
value from 1 to 255 to expose more bugs. If you need to reproduce a
crash use 'show environment' in gdb to extract the MALLOC_PERTURB_
value from a core dump.
Both make check and qemu-iotests pass with MALLOC_PERTURB_ enabled.

This adds an -o option to qemu-iotests, which is an option string that
is passed through to qemu-img create -o... This allows testing different
subformat with a command like './check -qcow2 -o compat=0.10'.
For qcow2, if no compat option is specified, compat=1.1 is the new
default.

qemu-iotests supports the -nocache option which makes the tests run with
cache=none. For blkdebug tests with qcow2 this means that we may see
test results that differ from cache=writethrough. This patch makes the
diff a bit smaller and therefore easier to review.
