Until now, with auto-read-only=on we tried to open the file read-write
first and if that failed, read-only was tried. This is actually not good
enough for libvirt, which gives QEMU SELinux permissions for read-write
only as soon as it actually intends to write to the image. So we need to
be able to switch between read-only and read-write at runtime.
This patch makes auto-read-only dynamic, i.e. the file is opened
read-only as long as no user of the node has requested write
permissions, but it is automatically reopened read-write as soon as the
first writer is attached. Conversely, if the last writer goes away, the
file is reopened read-only again.
bs->read_only is no longer set for auto-read-only=on files even if the
file descriptor is opened read-only because it will be transparently
upgraded as soon as a writer is attached. This changes the output of
qemu-iotests 232.

Using a different read-only setting for bs->open_flags than for the
flags to the driver's open function is just inconsistent and a bad idea.
After this patch, the temporary snapshot keeps being opened read-only if
read-only=on,snapshot=on is passed.
If we wanted to change this behaviour to make only the orginal image
file read-only, but the temporary overlay read-write (as the comment in
the removed code suggests), that change would have to be made in
bdrv_temp_snapshot_options() (where the comment suggests otherwise).
Addressing this inconsistency before introducing dynamic auto-read-only
is important because otherwise we would immediately try to reopen the
temporary overlay even though the file is already unlinked.

tests/virtio-blk-test uses a temporary image file that it deletes while
QEMU is still running, so it can't be reopened when writers are
attached or detached. Disable auto-read-only to keep it always writable.

Pointer authentication isn't guaranteed to always detect a clash

This introduces the build framework for simple i386 system tests. The
first test is the eponymous "Hello World" which simply outputs the
text on the serial port and then exits.
I've included the framework for x86_64 but it is not in this series as
it is a work in progress.

This converts the existing Makefile into a Makefile.target and updates
it so it can be called by the tcg build system. The original Makefile
didn't set -cpu except for the v17 tests however that has broken (I
assume because linux-user is a "max" cpu) so here I force it to be
crisv17.
I've also replicated the GNU simulator targets (run-FOO-on-sim).

Bare tests are standalone assembly tests that don't require linking to
any libc and hence can be built with kernel only compilers. The libc
tests need a compiler capable of building properly linked userspace
binaries. As we don't have such a cross compiler at the moment we
won't be building those tests.

This is a mini library which provides helper functions to the tests
which are all currently written in assembly. A bunch of minor changes:
- removed libc related headers (fedora-cris-cross is a system compiler)
- re-organised the functions to avoid forward declarations
- cleaned up brace usage
- restored exit for _fail case
- removed tabs and fixed indentation

We can't rely on shell redirect magic to get things right so lets
setup a common output chardev that is expecting to write to files. As
we have split run-test up we might as well move the default monitor
bits into the call.
Finally a little make sophistry is required to correctly quote
$(COMMA) and as we don't inherit common rules we have our own little
copy here.

The current API allows us to report a single status, which we've defined as:
Frozen: has a successor, treated as qmp_locked, may or may not be enabled.
Locked: no successor, qmp_locked. may or may not be enabled.
Disabled: Not frozen or locked, disabled.
Active: Not frozen, locked, or disabled.
The problem is that both "Frozen" and "Locked" mean nearly the same thing,
and that both of them do not intuit whether they are recording guest writes
or not.
This patch deprecates that status field and introduces two orthogonal
properties instead to replace it.

Managing parallel connections to two different monitors via
the implicit global_qtest makes it hard to copy-and-paste code
to tests that are not aware of the implicit state; the
management of global_qtest is even harder to follow because
it was masked behind set_context().
Instead, explicitly pass QTestState* around (generally, by
reusing the member already present in ahci->parent QOSState),
and call explicit qtest_* functions on all places that
interact with a monitor.
We can assert that the conversion is correct by checking that
global_qtest remains NULL throughout the test (a later patch
that changes global_qtest to not be a public global variable
will drop the assertions).

The new pseries-4.0 machine type defaults to enabling Spectre/Meltdown
mitigations. Unfortunately those mitigations aren't implemented for TCG
because we're not yet sure if they're necessary or how to implement them.
We don't fail fatally, but we do warn in this case, because it is quite
plausible that Spectre/Meltdown can be exploited through TCG (at least for
the guest to get access to the qemu address space).
This create noise in our testcases though. So, modify the affected tests
to explicitly disable the mitigations to suppress these warnings.

If seals are not supported, memfd_create() will fail.
Furthermore, there is no way to disable it in this case because
'.seal' property is not registered.

failed to create memfd: Invalid argument
and actually breaks the feature on such systems.
