Using g_spawn_async_with_pipes() is more complicated than running the
sync version. The async version returns a file descriptor for stdout, which may
not be fully read. Sometime "--tpm2" will failed to be read, and will
cause the related test to be silently skipped.
Use g_spawn_sync() instead, simplifying the code and fixing the race.

bdrv_img_create() takes an Error ** argument and uses it in the
conventional way, except for one place: when qemu_opts_do_parse()
fails, it first reports its error to stderr or the HMP monitor with
error_report_err(), then error_setg()'s a generic error.
When the caller reports that second error similarly, this produces two
consecutive error messages on stderr or the HMP monitor.
When the caller does something else with it, such as send it via QMP,
the first error still goes to stderr or the HMP monitor. Fortunately,
no such caller exists.
Simply use the first error as is. Update expected output of
qemu-iotest 049 accordingly.

GNU make is perfectly happy to use 'check-FOO-y += bar' to
initialize check-FOO-y. (GNU Automake strictly insists that
you cannot use += until after an initial = per variable, but
thankfully we aren't using automake).
As we have had more than one instance where copy-and-paste of
'check-FOO-y = bar' from a first test under category FOO into
an additional test, which ends up disabling the first (see
commits 992159c7 and 4429532b), it's better to just always use
the form that survives copy-and-paste, even for categories that
don't currently add more than one test.

Several changes:
- We only allow generate header "inside" the tree. Why? Because we
need to connit the result, so it makes no sense to generate them on
the build dir.
- We only generate a single target each time. Getting all the
cross-compilers correctly is an impossible task. So know you do:
make -C tests/migration $target (native)
make CROSS_PREFIX=foo- -C tests/migratiion $target (cross)
And you are done.
- If we are building out of tree, we have no data about if we are
cross-compile or whatever. So instead of guess what is happening,
just do what I pointed on previous point.

Fixed up Makefile since the aarch patch sneaked in first
This patch adds migration test support for aarch64. The test code, which
implements the same functionality as x86, is booted as a kernel in qemu.
Here are the design choices we make for aarch64:
* We choose this -kernel approach because aarch64 QEMU doesn't provide a
built-in fw like x86 does. So instead of relying on a boot loader, we
use -kernel approach for aarch64.
* The serial output is sent to PL011 directly.
* The physical memory base for mach-virt machine is 0x40000000. We change
the start_address and end_address for aarch64.
In addition to providing the binary, this patch also includes the source
code and the build script in tests/migration/aarch64. So users can change
the source and/or re-compile the binary as they wish.

It is yet unclear whether this should really be considered a bug in the

taken the AioContext lock, but in order to fix the build tests quickly,
just take the AioContext lock around blk_unref().

Currently, the default values for werror and rerror have to be set
explicitly with blk_set_on_error() by the callers of blk_new(). The only
caller actually doing this is blockdev_init(), which is called for
BlockBackends created using -drive.
In particular, anonymous BlockBackends created with
-device ...,drive=<node-name> didn't get the correct default set and
instead defaulted to the integer value 0 (= BLOCKDEV_ON_ERROR_REPORT).
This is the intended default for rerror anyway, but the default for
werror should be BLOCKDEV_ON_ERROR_ENOSPC.
Set the defaults in blk_new() instead so that they apply no matter what
way the BlockBackend was created.

Sufficient L2 cache can noticeably improve the performance when using
large images with frequent I/O.
Previously, unless 'cache-size' was specified and was large enough, the
L2 cache was set to a certain size without taking the virtual image size
into account.
Now, the L2 cache assignment is aware of the virtual size of the image,
and will cover the entire image, unless the cache size needed for that is
larger than a certain maximum. This maximum is set to 1 MB by default
(enough to cover an 8 GB image with the default cluster size) but can
be increased or decreased using the 'l2-cache-size' option. This option
was previously documented as the *maximum* L2 cache size, and this patch
makes it behave as such, instead of as a constant size. Also, the
existing option 'cache-size' can limit the sum of both L2 and refcount
caches, as previously.

Precomputing the hash values allows us to perform more frequent
accesses to the hash table, thereby reaching higher throughputs.
We keep the old behaviour by default, since (1) we might confuse
users if they measured a speedup without changing anything in
the QHT implementation, and (2) benchmarking the hash function
"on line" is also valuable.
Before:
$ taskset -c 0 tests/qht-bench -n 1
Throughput: 38.18 MT/s

$ taskset -c 0 tests/qht-bench -n 1

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.

Recently a new configure option, CROSS_CC_GUEST, was added to
$(TARGET)-softmmu/config-target.mak to support TCG-related tests. This
patch tries to leverage this option to support cross compilation when the
migration boot block file is being re-generated:
* The x86 related files are moved to a new sub-dir (named ./i386).
* A new top-layer Makefile is created in tests/migration/ directory.
This Makefile searches and parses CROSS_CC_GUEST to generate CROSS_PREFIX.
The CROSS_PREFIX, if available, is then passed to migration/$ARCH/Makefile.

The x86 boot block header currently is generated with a shell script.
To better support other CPUs (e.g. aarch64), we convert the script
into Makefile. This allows us to 1) support cross-compilation easily,
and 2) avoid creating a script file for every architecture.
Note that, in the new design, the cross compiler prefix can be specified by
setting the CROSS_PREFIX in "make" command. Also to allow gcc pre-processor
to include the C-style file correctly, it also renames the
x86-a-b-bootblock.s file extension from .s to .S.

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.

Here are the accumulated ppc target patches for the last several
weeks. Highlights are:
* A number of 40p / PReP cleanups
* Preliminary irq rework on the pseries machine towards the new
XIVE interrupt controller
There are a few patches which make small changes to generic device and
arm code as prerequisites to the 40p interrupt routing cleanup. They
have acks from the relevant maintainers.

This is a small test that will check for the ability to parse
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
qemu-img complaining about mandatory options (e.g. 'pool') not being
provided.

Here's another pull request for qemu-3.1. No real theme here, just an
assortment of various fixes. Probably the most notable thing is the
removal of the ppcemb target which has been deprecated for some time
now.

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.
