Perform first the tests that exercise code paths that are
easier to hit at small table sizes, and then resize the table
to speed up subsequent tests. If this resize is not too large,
we can make the test faster with no code coverage loss.
- With gcov enabled:
Before: 20.568s, 90.28% qht.c coverage
After: 5.168s, 93.06% qht.c coverage
The coverage increase is entirely due to calling qht_resize,
which we weren't calling before. Note that the code paths
that remain to be tested are either error handling or
can only occur when several threads are accessing the
hash table concurrently (e.g. seqlock retry, trylock fail).
- Without gcov:
Before: 1.987s
After: 0.528s
The speedup is almost the same as with gcov, although the
"before" run is a lot faster.

For the block job drain test, don't only test draining the source and
the target node, but create a backing chain for the source
(source_backing <- source <- source_overlay) and test draining each of
the nodes in it.
When using iothreads, the source node (and therefore the job) is in a
different AioContext than the drain, which happens from the main
thread. This way, the main thread waits in AIO_WAIT_WHILE() for the
iothread to make process and aio_wait_kick() is required to notify it.
The test validates that calling bdrv_wakeup() for a child or a parent
node will actually notify AIO_WAIT_WHILE() instead of letting it hang.
Increase the sleep time a bit (to 1 ms) because the test case is racy
and with the shorter sleep, it didn't reproduce the bug it is supposed
to test for me under 'rr record -n'.
This was because bdrv_drain_invoke_entry() (in the main thread) was only
called after the job had already reached the pause point, so we got a
bdrv_dec_in_flight() from the main thread and the additional
aio_wait_kick() when the job becomes idle (that we really wanted to test
here) wasn't even necessary any more to make progress.

This is a regression test for a deadlock that could occur in callbacks

both legacy and modern options for rbd.
The way the test is set up is for failure to occur, but without
having to wait to timeout on a non-existent rbd server. The error
messages in the success path show that the arguments were parsed.
The failure behavior prior to the patch series that has this test, is

When the lexer chokes on an input character, it consumes the
character, emits a JSON error token, and enters its start state. This
can lead to suboptimal error recovery. For instance, input
0123 ,
produces the tokens
JSON_ERROR 01
JSON_INTEGER 23
JSON_COMMA ,
Make the lexer skip characters after a lexical error until a
structural character ('[', ']', '{', '}', ':', ','), an ASCII control
character, or '\xFE', or '\xFF'.
Note that we must not skip ASCII control characters, '\xFE', '\xFF',
because those are documented to force the JSON parser into known-good
state, by docs/interop/qmp-spec.txt.
The lexer now produces
JSON_ERROR 01
JSON_COMMA ,
Update qmp-test for the nicer error recovery: QMP now reports just one
error for input %p instead of two. Also drop the newline after %p; it
was needed to tease out the second error.

Utilize the job_exit shim by not calling job_defer_to_main_loop, and
where applicable, converting the deferred callback into the job_exit
callback.
This converts backup, stream, create, and the unit tests all at once.
Most of these jobs do not see any changes to the order in which they
clean up their resources, except the test-blockjob-txn test, which
now puts down its bs before job_completed is called.
This is safe for the same reason the reordering in the mirror job is
safe, because job_completed no longer runs under two locks, making
the unref safe even if it causes a flush.

Verify the usage of this schema feature and the API behaviour. This
should be the only case where qmp_dispatch() returns NULL.

test_qom_set_without_value() is about a bug in infrastructure used by
the QMP core, fixed in commit c489780203. We covered the bug in
infrastructure unit tests (commit bce3035a44). I wrote that test
earlier, to cover QMP level as well, the test could go into qmp-test.

test_object_add_without_props() tests a bug in qmp_object_add() we
fixed in commit e64c75a975. Sadly, we don't have systematic
object-add tests. This lone test can go into qmp-cmd-test for want of
a better home.

This helper will simplify a bunch of code checking for QMP errors and
can be shared by various tests. Note that test-qga does check for
error description as well, so don't replace the code there for now.

During development, I got a 'make check' failure that claimed:
qemu-img returned status code 32512
**
ERROR:tests/libqos/libqos.c:202:mkimg: assertion failed: (!rc)
But 32512 is too big for a normal exit status value, which means we
failed to use WEXITSTATUS() to shift the bits to the desired value
for printing. However, instead of worrying about how to portably
parse g_spawn()'s rc in the proper platform-dependent manner, it's
better to just rely on the fact that we now require glib 2.40 (since
commit e7b3af815) and can therefore use glib's portable checker
instead, where the message under my same condition improves to:
Child process exited with code 127
**
ERROR:tests/libqos/libqos.c:192:mkimg: assertion failed: (ret && !err)
