In qmp_transaction(), we can't just drop parameter @has_props, since
it's used to track whether @props needs to be freed.  Replace it by a
local variable.

Additionally, helper bdrv_latency_histogram_stats() loses its output
parameters and returns a value instead.

Tweak the semantic patch to drop redundant parenthesis around the
return expression.

Coccinelle drops a comment in hw/rdma/vmw/pvrdma_cmd.c; restored
manually.

Coccinelle messes up vmdk_co_create(), not sure why.  Change dropped,
will be done manually in the next commit.

Line breaks in target/avr/cpu.h and hw/rdma/vmw/pvrdma_cmd.c tidied up
manually.

Whitespace in tools/virtiofsd/fuse_lowlevel.c tidied up manually.

checkpatch.pl complains "return of an errno should typically be -ve"
two times for hw/9pfs/9p-synth.c.  Preexisting, the patch merely makes
it visible to checkpatch.pl.

d1c81c3496 qapi: Use returned bool to check for failure (again)
Commit 012d4c96e2 changed the visitor functions taking Error ** to
return bool instead of void, and the commits following it used the new
return value to simplify error checking.  Since then a few more uses
in need of the same treatment crept in.  Do that.  All pretty
mechanical except for

* balloon_stats_get_all()

  This is basically the same transformation commit 012d4c96e2 applied
  to the virtual walk example in include/qapi/visitor.h.

* set_max_queue_size()

  Additionally replace "goto end of function" by return.

6c37ebf330 error: Drop some obviously superfluous error_propagate()
When error_propagate(errp, local_err) is the only reader of
@local_err, we can just as well change its writers to write @errp
directly, and drop the error_propagate() along with @local_err.

8461b4d601 nbd/server: Clean up abuse of BlockExportOptionsNbd member @arg
block-export-add argument @name defaults to the value of argument
@node-name.

nbd_export_create() implements this by copying @node_name to @name.
It leaves @has_node_name false, violating the "has_node_name ==
!!node_name" invariant.  Unclean.  Falls apart when we elide
@has_node_name (next commit): then QAPI frees the same value twice,
once for @node_name and once @name.  iotest 307 duly explodes.

Goes back to commit c62d24e906 "blockdev-nbd: Boxed argument type for
nbd-server-add" (v5.0.0).  Got moved from qmp_nbd_server_add() to
nbd_export_create() (commit 56ee86261e), then copied back (commit
b6076afcab).  Commit 8675cbd68b "nbd: Utilize QAPI_CLONE for type
conversion" (v5.2.0) cleaned up the copy in qmp_nbd_server_add()
noting

    Second, our assignment to arg->name is fishy: the generated QAPI code
    for qapi_free_NbdServerAddOptions does not visit arg->name if
    arg->has_name is false, but if it DID visit it, we would have
    introduced a double-free situation when arg is finally freed.

Exactly.  However, the copy in nbd_export_create() remained dirty.

Clean it up.  Since the value stored in member @name is not actually
used outside this function, use a local variable instead of modifying
the QAPI object.

04658a5b90 blockdev: Clean up abuse of DriveBackup member format
drive-backup argument @format defaults to the format of the source
unless @mode is "existing".

drive_backup_prepare() implements this by copying the source's
@format_name to DriveBackup member @format.  It leaves @has_format
false, violating the "has_format == !!format" invariant.  Unclean.
Falls apart when we elide @has_format (commit after next): then QAPI
passes @format, which is a string constant, to g_free().  iotest 056
duly explodes.

ceb19c8f68 qapi audio: Elide redundant has_FOO in generated C
The has_FOO for pointer-valued FOO are redundant, except for arrays.
They are also a nuisance to work with.  Recent commit "qapi: Start to
elide redundant has_FOO in generated C" provided the means to elide
them step by step.  This is the step for qapi/audio.json.

Said commit explains the transformation in more detail.  The invariant
violations mentioned there do not occur here.

Additionally, helper get_str() loses its @has_dst parameter.

44ea9d9be3 qapi: Start to elide redundant has_FOO in generated C
In QAPI, absent optional members are distinct from any present value.
We thus represent an optional schema member FOO as two C members: a
FOO with the member's type, and a bool has_FOO.  Likewise for function
arguments.

However, has_FOO is actually redundant for a pointer-valued FOO, which
can be null only when has_FOO is false, i.e. has_FOO == !!FOO.  Except
for arrays, where we a null FOO can also be a present empty array.

The redundant has_FOO are a nuisance to work with.  Improve the
generator to elide them.  Uses of has_FOO need to be replaced as
follows.

Tests of has_FOO become the equivalent comparison of FOO with null.
For brevity, this is commonly done by implicit conversion to bool.

Assignments to has_FOO get dropped.

Likewise for arguments to has_FOO parameters.

Beware: code may violate the invariant has_FOO == !!FOO before the
transformation, and get away with it.  The above transformation can
then break things.  Two cases:

* Absent: if code ignores FOO entirely when !has_FOO (except for
  freeing it if necessary), even non-null / uninitialized FOO works.
  Such code is known to exist.

* Present: if code ignores FOO entirely when has_FOO, even null FOO
  works.  Such code should not exist.

In both cases, replacing tests of has_FOO by FOO reverts their sense.
We have to fix the value of FOO then.

To facilitate review of the necessary updates to handwritten code, add
means to opt out of this change, and opt out for all QAPI schema
modules where the change requires updates to handwritten code.  The
next few commits will remove these opt-outs in reviewable chunks, then
drop the means to opt out.
