Marc-André Lureau cb3e7f08ae qobject: Replace qobject_incref/QINCREF qobject_decref/QDECREF
Now that we can safely call QOBJECT() on QObject * as well as its
subtypes, we can have macros qobject_ref() / qobject_unref() that work
everywhere instead of having to use QINCREF() / QDECREF() for QObject
and qobject_incref() / qobject_decref() for its subtypes.

The replacement is mechanical, except I broke a long line, and added a
cast in monitor_qmp_cleanup_req_queue_locked().  Unlike
qobject_decref(), qobject_unref() doesn't accept void *.

Note that the new macros evaluate their argument exactly once, thus no
need to shout them.

Eric Blake 3d95fb9770 libqos: Use explicit QTestState for remaining libqos operations
Drop one more client of global_qtest by teaching all remaining
libqos stragglers to pass in an explicit QTestState.  Change the
setting of global_qtest from being implicit in libqos' call to
qtest_start() to instead be explicit in all clients that are
still relying on global_qtest.

Note that qmp_execute() can be greatly simplified in the process,
and that we also get rid of interpolation of a JSON string into a
temporary variable when qtest_qmp() can do it more reliably.

Markus Armbruster 452fcdbc49 Include qapi/qmp/qdict.h exactly where needed
This cleanup makes the number of objects depending on qapi/qmp/qdict.h
drop from 4550 (out of 4743) to 368 in my "build everything" tree.
For qapi/qmp/qobject.h, the number drops from 4552 to 390.

While there, separate #include from file comment with a blank line.

Greg Kurz be3a678160 libqos/virtio: return length written into used descriptor
When a 9p request is flushed (ie, cancelled) by the guest, the device
is expected to simply mark the request as used, without sending a 9p
reply (ie, without writing anything into the used buffer).

To be able to test this, we need access to the length written by the
device into the used descriptor. This patch adds a uint32_t * argument
to qvirtqueue_get_buf() and qvirtio_wait_used_elem() for this purpose.

All existing users are updated accordingly.

Laurent Vivier a980f7f2c2 tests: use qtest_pc_boot()/qtest_shutdown() in virtio tests
This patch replaces calls to qtest_start() and qtest_end() by
calls to qtest_pc_boot() and qtest_shutdown().

This allows to initialize memory allocator and PCI interface
functions. This will ease to enable virtio tests on other
architectures by only adding a specific qtest_XXX_boot() (like
qtest_spapr_boot()).

Eduardo Habkost 9be385980d coccinelle: Remove unnecessary variables for function return value
Use Coccinelle script to replace 'ret = E; return ret' with
'return E'. The script will do the substitution only when the
function return type and variable type are the same.

Manual fixups:

* audio/audio.c: coding style of "read (...)" and "write (...)"
* block/qcow2-cluster.c: wrap line to make it shorter
* block/qcow2-refcount.c: change indentation of wrapped line
* target-tricore/op_helper.c: fix coding style of
  "remainder|quotient"
* target-mips/dsp_helper.c: reverted changes because I don't

Stefan Hajnoczi ee3b850a70 libqos: drop duplicated virtio_ring.h bit definitions
Note that virtio_ring.h defines feature bits using their bit number:

  #define VIRTIO_RING_F_INDIRECT_DESC     28

On the other hand libqos virtio.h uses the bit mask:

  #define QVIRTIO_F_RING_INDIRECT_DESC    0x10000000

The patch makes the necessary adjustments.

I have used "1u << BITMASK" instead of "1ULL << BITMASK" because the
64-bit feature fields are not implemented in libqos virtio.
