Commit 934659c switched the iotests to run qemu-io from a bash subshell,
in order to catch segfaults. This method is incompatible with the
current valgrind_qemu_io() bash function.
Move the valgrind usage into the exec subshell in _qemu_io_wrapper(),
while making sure the original return value is passed back to the
caller.
Update test output for tests 039, 061, and 137 as it looks for the
specific subshell command when the process is terminated.

Commit 934659c460 disabled the supression of segmentation faults in
bash tests. The new output of test 061, however, assumes that a core
dump will be produced if a program aborts. This is not necessarily the
case because core dumps can be disabled using ulimit.
Since we cannot guarantee that abort() will produce a core dump, we
should use SIGKILL instead (that does not produce any) and update the
test output accordingly.

This will let us print options in a format that the user would actually
write it on the command line (foo=bar,baz=asd,etc=def), without
prepending a spurious comma at the beginning of the list, or quoting
values unnecessarily. This patch provides the following changes:
* write and id=, if the option has an id
* do not print separator before the first element
* do not quote string arguments
* properly escape commas (,) for QEMU

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.

039, 060 and 061 all create images with referenced clusters having a
refcount of 0. Because previous commits changed handling of such errors,
these tests now have a different output. Fix it.
Furthermore, 060 created a refblock with a refcount greater than one
which now results in having to rebuild the refcount structure as well.

Change block layer to support both QemuOpts and QEMUOptionParameter.
After this patch, it will change backend drivers one by one. At the end,
QEMUOptionParameter will be removed and only QemuOpts is kept.
