5325cc34a2 qom: Put name parameter before value / visitor parameter
The object_property_set_FOO() setters take property name and value in
an unusual order:

    void object_property_set_FOO(Object *obj, FOO_TYPE value,
                                 const char *name, Error **errp)

object_property_parse().

1c94a35164 qom: Use return values to check for error where that's simpler
When using the Error object to check for error, we need to receive it
into a local variable, then propagate() it to @errp.

Using the return value permits allows receiving it straight to @errp.

3882578bb5 block: Avoid error accumulation in bdrv_img_create()
When creating an image fails because the format doesn't support option
"backing_file" or "backing_fmt", bdrv_img_create() first has
qemu_opt_set() put a generic error into @local_err, then puts the real
error into @errp with error_setg(), and then propagates the former to
the latter, which throws away the generic error.  A bit complicated,
but works.

Now that qemu_opt_set() returns a useful value, we can simply ignore
the generic error instead.

64af7a8bad qemu-option: Replace opt_set() by cleaner opt_validate()
opt_set() frees its argument @value on failure.  Slightly unclean;
functions ideally do nothing on failure.

To tidy this up, move opt_create() from opt_set() into its callers,
along with the cleanup.  Rename opt_set() to opt_validate(), noting
its similarity to qemu_opts_validate().  Drop redundant parameter
@opts; use opt->opts instead.

Eliminate error_propagate() that are now unnecessary.  Delete @err

Note that we can't drop parallels_open()'s error_propagate() here.  We
continue to execute it even in the converted case.  It's a no-op then:
local_err is null.

Chokes on hw/arm/musicpal.c's lcd_refresh() with the unhelpful error
message "no position information".  Nothing to convert there; skipped.

Fails to convert hw/arm/armsse.c, because Coccinelle gets confused by
ARMSSE being used both as typedef and function-like macro there.
Converted manually.

A few line breaks tidied up manually.

e3fe3988d7 error: Document Error API usage rules
This merely codifies existing practice, with one exception: the rule
advising against returning void, where existing practice is mixed.

When the Error API was created, we adopted the (unwritten) rule to
return void when the function returns no useful value on success,
unlike GError, which recommends to return true on success and false on
error then.

When a function returns a distinct error value, say false, a checked
call that passes the error up looks like

    if (!frobnicate(..., errp)) {
        handle the error...
    }

When it returns void, we need

    Error *err = NULL;

    frobnicate(..., &err);
    if (err) {
        handle the error...
        error_propagate(errp, err);
    }

Not only is this more verbose, it also creates an Error object even
when @errp is null, &error_abort or &error_fatal.

People got tired of the additional boilerplate, and started to ignore
the unwritten rule.  The result is confusion among developers about
the preferred usage.

Make the rule advising against returning void official by putting it
in writing.  This will hopefully reduce confusion.

Update the examples accordingly.

The remainder of this series will update a substantial amount of code
to honor the rule.

   (+ patches to make the iotests pass on non-Linux systems, and to keep
      the tests passing for qcow v1, and to skip LUKS tests (including
      qcow2 LUKS) when the built qemu does not support it)
 - Refactoring in the block layer: Drop the basically unnecessary
   unallocated_blocks_are_zero field from BlockDriverInfo
 - Fix qcow2 preallocation when the image size is not a multiple of the
   cluster size
 - Fix in block-copy code

27e08bab94 tracetool: work around ust <sys/sdt.h> include conflict
Both the dtrace and ust backends may include <sys/sdt.h> but LTTng
Userspace Tracer 2.11 and later requires SDT_USE_VARIADIC to be defined
before including the header file.

This is a classic problem with C header files included from different
parts of a program. If the same header is included twice within the same
compilation unit then the first inclusion determines the macro
environment.

Work around this by defining SDT_USE_VARIADIC in the dtrace backend too.
It doesn't hurt and fixes a missing STAP_PROBEV() compiler error when
the ust backend is enabled together with the dtrace backend.
