Sometimes, the behaviour of QEMU changes without a change in the QMP
syntax (usually by allowing values or operations that previously
resulted in an error). QMP clients may still need to know whether
they can rely on the changed behavior.
Let's add feature flags to the QAPI schema language, so that we can make
such changes visible with schema introspection.
An example for a schema definition using feature flags looks like this:
{ 'struct': 'TestType',
'data': { 'number': 'int' },
'features': [ 'allow-negative-numbers' ] }
Introspection information then looks like this:
{ "name": "TestType", "meta-type": "object",
"members": [
{ "name": "number", "type": "int" } ],
"features": [ "allow-negative-numbers" ] }
This patch implements feature flags only for struct types. We'll
implement them more widely as needed.

This is the common header guard idiom:
/*

*/
#ifndef GUARD_SYMBOL_H
#define GUARD_SYMBOL_H
... actual contents ...
#endif
A few of our headers have some #include before the guard.
target/tilegx/spr_def_64.h has #ifndef __DOXYGEN__ outside the guard.
A few more have the #define elsewhere.
Change them to match the common idiom. For spr_def_64.h, that means
dropping #ifndef __DOXYGEN__. While there, rename guard symbols to

This patch adds a test where we cancel a throttled mirror job and

invoke bdrv_drain_all() while the mirror job tries to drain the
throttled node. When bdrv_drain_all_end() tries to lift its drain on
the throttle node, the job will exit and replace the current root node
of the BB drive0 (which is the job's filter node) by the throttle node.
Before the previous patch, this replacement did not increase drive0's
quiesce_counter by a sufficient amount, so when
bdrv_parent_drained_end() (invoked by bdrv_do_drained_end(), invoked by
bdrv_drain_all_end()) tried to end the drain on all of the throttle
node's parents, it decreased drive0's quiesce_counter below 0 -- which

drv_co_block_status digs bs->file for additional, more accurate search
for hole inside region, reported as DATA by bs since 5daa74a6eb.
This accuracy is not free: assume we have qcow2 disk. Actually, qcow2
knows, where are holes and where is data. But every block_status
request calls lseek additionally. Assume a big disk, full of
data, in any iterative copying block job (or img convert) we'll call
lseek(HOLE) on every iteration, and each of these lseeks will have to
iterate through all metadata up to the end of file. It's obviously
ineffective behavior. And for many scenarios we don't need this lseek
at all.
However, lseek is needed when we have metadata-preallocated image.
So, let's detect metadata-preallocation case and don't dig qcow2's
protocol file in other cases.
The idea is to compare allocation size in POV of filesystem with
allocations size in POV of Qcow2 (by refcounts). If allocation in fs is
significantly lower, consider it as metadata-preallocation case.
102 iotest changed, as our detector can't detect shrinked file as
metadata-preallocation, which don't seem to be wrong, as with metadata
preallocation we always have valid file length.
Two other iotests have a slight change in their QMP output sequence:
Active 'block-commit' returns earlier because the job coroutine yields
earlier on a blocking operation. This operation is loading the refcount
blocks in qcow2_detect_metadata_preallocation().
