John Snow 4cf661f2c0 iotests: remove remaining calls to qemu_img_pipe()
As part of moving all python iotest invocations of qemu-img onto a
single qemu_img() implementation, remove a few lingering uses of
qemu_img_pipe() from outside of iotests.py itself.

Several cases here rely on the knowledge that qemu_img_pipe() suppresses
*all* output on a successful case when the command being issued is
'create'.

065: This call's output is inspected, but it appears as if it's expected
     to succeed. Replace this call with the checked qemu_img() variant
     instead to get better diagnostics if/when qemu-img itself fails.

237: "create" call output isn't actually logged. Use qemu_img_create()
     instead, which checks the return code. Remove the empty lines from
     the test output.

296: Two calls;
     -create: Expected to succeed. Like other create calls, the output
              isn't actually logged.  Switch to a checked variant
              (qemu_img_create) instead. The output for this test is
              a mixture of both test styles, so actually replace the
              blank line for readability.
     -amend:  This is expected to fail. Log the output.

After this patch, the only uses of qemu_img_pipe are internal to
iotests.py and will be removed in subsequent patches.

Emanuele Giuseppe Esposito c1019d1687 crypto: perform permission checks under BQL
Move the permission API calls into driver-specific callbacks
that always run under BQL. In this case, bdrv_crypto_luks
needs to perform permission checks before and after
qcrypto_block_amend_options(). The problem is that the caller,
block_crypto_amend_options_generic_luks(), can also run in I/O
from .bdrv_co_amend(). This does not comply with Global State-I/O API split,
as permissions API must always run under BQL.

Firstly, introduce .bdrv_amend_pre_run() and .bdrv_amend_clean()
callbacks. These two callbacks are guaranteed to be invoked under
BQL, respectively before and after .bdrv_co_amend().
They take care of performing the permission checks
in the same way as they are currently done before and after
qcrypto_block_amend_options().
These callbacks are in preparation for next patch, where we
delete the original permission check. Right now they just add redundant
control.

Then, call .bdrv_amend_pre_run() before job_start in
qmp_x_blockdev_amend(), so that it will be run before the job coroutine
is created and stay in the main loop.
As a cleanup, use JobDriver's .clean() callback to call
.bdrv_amend_clean(), and run amend-specific cleanup callbacks under BQL.

After this patch, permission failures occur early in the blockdev-amend
job to update a LUKS volume's keys.  iotest 296 must now expect them in
x-blockdev-amend's QMP reply instead of waiting for the actual job to
fail later.

Vladimir Sementsov-Ogievskiy 9dd003a998 iotests: define group in each iotest
We are going to drop group file. Define group in tests as a preparatory
step.

The patch is generated by

    cd tests/qemu-iotests

    grep '^[0-9]\{3\} ' group | while read line; do
        file=$(awk '{print $1}' <<< "$line");
        groups=$(sed -e 's/^... //' <<< "$line");
        awk "NR==2{print \"# group: $groups\"}1" $file > tmp;
        cat tmp > $file;
