dd21074972 tests/libqtest: Use libqtest-single.h in tests that require global_qtest
Tests that require global_qtest or the related wrapper functions now
use the libqtest-single.h header that is dedicated for everything
related to global_qtest. The core libqtest.c and libqtest.h files are
now completely indepedent from global_qtest, so that the core library
is now not depending on a global state anymore.

0ba67974af tests/libqtest: Move global_test wrapper function into a separate header
We want libqtest.h to become completely independent from global_qtest
(so that the wrapper functions are not used by accident anymore). As
a first step, move the wrapper functions into a separate header file.

The new header is only included from libqtest.h for now, so that there
is no difference to the users of libqtest.h yet. In the next patch, we
will switch this, so that the users of the global_qtest-related
functions will be using libqtest-single.h directly and libqtest.h
becomes completely independent of this.

6fc9f3d347 tests/libqtest: Make qmp_assert_success() independent from global_qtest
The normal libqtest library functions should never depend on global_qtest.
Pass in the test state via parameter instead. And while we're at it,
also rename this function to qtest_qmp_assert_success() to make it clear
that it is part of libqtest.

e2f64a688b test-qga: Clean up how we test QGA synchronization
To permit recovering from arbitrary JSON parse errors, the JSON parser
resets itself on lexical errors.  We recommend sending a 0xff byte for
that purpose, and test-qga covers this usage since commit 5229564b83.
That commit had to add an ugly hack to qmp_fd_vsend() to make capable
of sending this byte (it's designed to send only valid JSON).

The previous commit added a way to send arbitrary text.  Put that to
use for this purpose, and drop the hack from qmp_fd_vsend().

1f4a0d81af tests: Skip old versioned machine types in quick testing mode
The tests that check something for all machine types currently spend
a lot of time checking old machine types (like "pc-i440fx-2.0" for
example). The chances that we find something new there in addition
to checking the latest version of a machine type are pretty low, so
we should not waste the time of the developers by testing this again
and again in the "quick" testing mode.
Thus let's add some code to determine whether we are testing a current
machine type or an old one, and only test the old types if we are
running in "SPEED=slow" mode.
This decreases the testing time quite a bit now, e.g. the qom-test
now finishes within 4 seconds for qemu-system-x86_64 instead of 30
seconds when testing all machines.

82cab70bd8 tests: Clean up string interpolation around qtest_qmp_device_add()
Leaving interpolation into JSON to qmp() is more robust than building
QMP input manually, as explained in the commit before previous.

qtest_qmp_device_add() and its wrappers interpolate into JSON as
follows:

* qtest_qmp_device_add() interpolates members into a JSON object.

* So do its wrappers qpci_plug_device_test() and usb_test_hotplug().

* usb_test_hotplug() additionally interpolates strings and numbers
  into JSON strings.

Clean them up:

* Have qtest_qmp_device_add() take its extra device properties as
  arguments for qdict_from_jsonf_nofail() instead of a string
  containing JSON members.

* Drop qpci_plug_device_test(), use qtest_qmp_device_add()
  directly.

* Change usb_test_hotplug() parameter @port to string, to avoid
  interpolation.  Interpolate @hcd_id separately.

Bonus: gets rid of a non-literal format string.  A step towards
compile-time format string checking without triggering
-Wformat-nonliteral.

6ce80fd803 qobject: Replace qobject_from_jsonf() by qobject_from_jsonf_nofail()
Commit ab45015a96 "qobject: Let qobject_from_jsonf() fail instead of
abort" fails to accomplish its stated aim: the function can still
abort due to its use of &error_abort.

Its rationale for letting it fail is that all remaining users cope
fine with failure.  Well, they're just fine with aborting, too; it's
what they do on failure.

Simply reverting the broken commit would bring back the unfortunate
asymmetry between qobject_from_jsonf() and qobject_from_jsonv(): one
aborts, the other returns null.  So also rename it to
qobject_from_jsonf_nofail().

Also add GCC_FMT_ATTR() to qtest_hmp() etc. so that the compiler can

We have some cleanup work to do before we can do the same for
qtest_qmp() etc.  This would get us the same better-than-nothing
checking we already have for qobject_from_jsonf(): common incorrect
uses of supported conversion specifications will be flagged

We have several callers that were formatting the argument strings
themselves; consolidate this effort by adding new convenience
functions directly in libqtest, and update some call-sites that
can benefit from it.

Note that the new functions qtest_startf() and qtest_vstartf()
behave more like qtest_init() (the caller must assign global_qtest
after the fact, rather than getting it implicitly set).  This helps
us prepare for future patches that get rid of the global variable,

7b899f4dd5 qtest: Avoid passing raw strings through hmp()
hmp() passes its string argument through the sprintf() family;
with a proper attribute, gcc -Wformat warns us when we do something
dangerous like passing a non-constant format string.  Fortunately,
all our strings were safe, but checking whether the string can
contain an unintended % is easy to avoid and therefore worth doing.

acd80015fb tests: Introduce generic device hot-plug/hot-unplug functions
A lot of tests provide code for adding and removing a device via the
device_add and device_del QMP commands. Maintaining this code in so many
places is cumbersome and error-prone (some of the code parts check the
responses for device deletion in an incorrect way, for example, we've got
to deal with both, error code and DEVICE_DEL event here). So let's provide
some proper generic functions for adding and removing a device instead.

The code for correctly unplugging a device has been taken from a patch
from Peter Xu.

6bb87be893 libqtest: Ignore QMP events when parsing the response for HMP commands
When running certain HMP commands (like "device_del") via QMP, we
can sometimes get a QMP event in the response first, so that the
"g_assert(ret)" statement in qtest_hmp() triggers and the test
fails. Fix this by ignoring such QMP events while looking for the
real return value from QMP.

The target endianness is not deduced anymore from
the architecture name but asked directly to the guest,
using a new qtest command: "endianness". As it can't
change (this is the value of TARGET_WORDS_BIGENDIAN),
we store it to not have to ask every time we want to
know if we have to byte-swap a value.

041088c719 tests: Use proper functions types instead of void (*fn)
We have several function parameters declared as void (*fn).  This is
just a stupid way to write void *, and the only purpose writing it
like that could serve is obscuring the sin of bypassing the type
system without need.

The original sin is commit 49ee359: its qtest_add_func() is a wrapper
for g_test_add_func().  Fix the parameter type to match
g_test_add_func()'s.  This uncovers type errors in ide-test.c; fix
them.

Commit 7949c0e faithfully repeated the sin for qtest_add_data_func().
Fix it the same way, along with a harmless type error uncovered in
vhost-user-test.c.

Commit 063c23d repeated it for qtest_add_abrt_handler().  The screwy
parameter gets assigned to GHook member func, so change its type to
match.  Requires wrapping kill_qemu() to keep the type checker happy.

7a6a740d8d qtest: Add base64 encoded read/write
For larger pieces of data that won't need to be debugged and
viewing the hex nibbles is unlikely to be useful, we can encode
data using base64 instead of encoding each byte as %02x, which
leads to some space savings and faster reads/writes.

For now, the default is left as hex nibbles in memwrite() and memread().
For the purposes of making qtest io easier to read and debug, some
callers may want to specify using the old encoding format for small
patches of data where the savings from base64 wouldn't be that profound.

memwrite/memread use a data encoding that takes 2x the size of the original
buffer, but base64 uses "only" (4/3)x, so for larger buffers we can save a
decent amount of time and space.
