eebf199c09 tests/tcg: invoke Makefile.target directly from QEMU's makefile
Build the "docker.py cc" invocation directly in tests/tcg/configure.sh, and
remove the Makefile.qemu wrapper around Makefile.target.  The config-*.mak
files now include the actual variables used when building the tests, rather
than the CROSS_* variables that Makefile.qemu used to "translate".

This is a first step towards generalizing the cross-compilation infrastructure
so that it can be used for firmware as well.

11593544df tests/avocado: update aarch64_virt test to exercise -cpu max
The Fedora 29 kernel is quite old and importantly fails when running
in LPA2 scenarios. As it's not really exercising much of the CPU space
replace it with a custom 5.16.12 kernel with all the architecture
options turned on. There is a minimal buildroot initramfs included in
the kernel which has a few tools for stress testing the memory
subsystem. The userspace also targets the Neoverse N1 processor so
would fail with a v8.0 cpu like cortex-a53.

While we are at it move the test into its own file so it can have an
assigned maintainer.

8e3b0cbb72 Replace qemu_real_host_page variables with inlined functions
Replace the global variables with inlined helper functions. getpagesize() is very
likely annotated with a "const" function attribute (at least with glibc), and thus
optimization should apply even better.

This avoids the need for a constructor initialization too.

e03b56863d Replace config-time define HOST_WORDS_BIGENDIAN
Replace a config-time define with a compile time condition
define (compatible with clang and gcc) that must be declared prior to
its usage. This avoids having a global configure time define, but also
prevents from bad usage, if the config header wasn't included before.

This can help to make some code independent from qemu too.

gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.

04cca669b2 tests/lcitool: Do not use a hard-coded /usr/bin/python3 as python interpreter
When running "make lcitool-refresh", this currently uses the hard-coded
/usr/bin/python3 from the script's shebang line for running Python.
That's bad, since neither /usr/bin/python3 is guaranteed to exist, nor
does it honor the python interpreter that the user might have chosen
while running the "configure" script. Thus let's rather use $(PYTHON)
in the Makefile, and improve the shebang line in the script in case
someone runs this directly.

d5699c0d4b iotests: Fix status checks
An iotest's 'paused' condition is fickle; it will be reported as true
whenever the job is drained, for example, or when it is in the process
of completing.

030 and 041 contain such checks, we should replace them by checking the
job status instead.  (As was done for 129 in commit f9a6256b48
for the 'busy' condition.)

Additionally, when we want to test that a job is paused on error, we
might want to give it some time to actually switch to the paused state.
Do that by waiting on the corresponding JOB_STATUS_CHANGE event.  (But
only if they are not already paused; the loops these places are in fetch
all VM events, so they may have already fetched that event from the
queue.)

b1e1af394d block/stream: Drain subtree around graph change
When the stream block job cuts out the nodes between top and base in
stream_prepare(), it does not drain the subtree manually; it fetches the
base node, and tries to insert it as the top node's backing node with
bdrv_set_backing_hd().  bdrv_set_backing_hd() however will drain, and so
the actual base node might change (because the base node is actually not
part of the stream job) before the old base node passed to
bdrv_set_backing_hd() is installed.

This has two implications:

First, the stream job does not keep a strong reference to the base node.
Therefore, if it is deleted in bdrv_set_backing_hd()'s drain (e.g.
because some other block job is drained to finish), we will get a
use-after-free.  We should keep a strong reference to that node.

Second, even with such a strong reference, the problem remains that the
base node might change before bdrv_set_backing_hd() actually runs and as
a result the wrong base node is installed.

Both effects can be seen in 030's TestParallelOps.test_overlapping_5()
case, which has five nodes, and simultaneously streams from the middle
node to the top node, and commits the middle node down to the base node.
As it is, this will sometimes crash, namely when we encounter the
above-described use-after-free.

Taking a strong reference to the base node, we no longer get a crash,
but the resuling block graph is less than ideal: The expected result is
obviously that all middle nodes are cut out and the base node is the
immediate backing child of the top node.  However, if stream_prepare()
takes a strong reference to its base node (the middle node), and then
the commit job finishes in bdrv_set_backing_hd(), supposedly dropping
that middle node, the stream job will just reinstall it again.

Therefore, we need to keep the whole subtree drained in
stream_prepare(), so that the graph modification it performs is
effectively atomic, i.e. that the base node it fetches is still the base
node when bdrv_set_backing_hd() sets it as the top node's backing node.

Verify this by asserting in said 030's test case that the base node is
always the top node's immediate backing child when both jobs are done.

48f1fcd5c8 iotests/207: Filter host fingerprint
Commit e3296cc796 made the ssh block
driver's error message for fingerprint mismatches more verbose, so it
now prints the actual host key fingerprint and the key type.

iotest 207 tests such errors, but was not amended to filter that
fingerprint (which is host-specific), so do it now.  Filter the key
type, too, because I guess this too can differ depending on the host
configuration.

da9d88d8e6 iotests.py: Filters for VM.run_job()
Allow filters for VM.run_job(), and pass the filters given to

(Use this opportunity to annotate VM.run_job()'s parameter types;
unfortunately, for the filter, I could not come up with anything better

At one point, a plain string is logged, so the filters passed to it must
work fine with plain strings.  The only filters passed to it at this
point are the ones from VM.blockdev_create(), which are
filter_qmp_test_files() (by default) and 207's filter_hash().  Both
cannot handle plain strings yet, but we can make them by amending
filter_qmp() to treat them as plain values with a None key.

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.

1670ae7af6 iotests: add qemu_img_map() function
Add a qemu_img_map() function by analogy with qemu_img_measure(),
qemu_img_check(), and qemu_img_info() that all return JSON information.

Replace calls to qemu_img_pipe('map', '--output=json', ...) with this
new function, which provides better diagnostic information on failure.

Note: The output for iotest 211 changes, because logging JSON after it
was deserialized by Python behaves a little differently than logging the
raw JSON document string itself.
(iotests.log() sorts the keys for Python 3.6 support.)
