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.

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.

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.

Merge remote-tracking branch 'remotes/huth-gitlab/tags/pull-request-2018-09-25' into staging
- Deprecate the usage of a network backend via "name" instead of "id"
- Deprecate the "enforce-config-section" machine parameter
- Re-enable the wdt_ib700, endianness and vmxnet3 qtests
- Some trivial fixes and doc update patches that crossed my way

The SLOF boot process is always quite slow ... but we can speed it up
a little bit by specifying "-nodefaults" and by using the "nvramrc"
variable instead of "boot-command" (since "nvramrc" is evaluated earlier
in the SLOF boot process than "boot-command").

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.

Commit 89bd030533 changed the test case from using job_sleep_ns() to
using qemu_co_sleep_ns() instead. Also, block_job_sleep_ns() became
job_sleep_ns() in commit 5d43e86e11.
In both cases, some comments in the test case were not updated. Do that
now.

This adds tests for calling AIO_WAIT_WHILE() in the .commit and .abort
callbacks. Both reasons why .abort could be called for a single job are
tested: Either .run or .prepare could return an error.

This is a regression test for a deadlock that could occur in callbacks
called from the aio_poll() in bdrv_drain_poll_top_level(). The
AioContext lock wasn't released and therefore would be taken a second
time in the callback. This would cause a possible AIO_WAIT_WHILE() in
the callback to hang.

This is a regression test for a deadlock that occurred in block job
completion callbacks (via job_defer_to_main_loop) because the AioContext
lock was taken twice: once in job_finish_sync() and then again in
job_defer_to_main_loop_bh(). This would cause AIO_WAIT_WHILE() to hang.

All callers in QEMU proper hold the AioContext lock when calling
job_finish_sync(). test-blockjob should do the same when it calls the
function indirectly through job_cancel_sync().
