'writeconfig' supports output to stdout (with '-'); when that happens,
we must not close stdout, or further command line options that also use
stdout will be impacted. (Although 'writeconfig' was copied from
'readconfig', the latter does not have the problem because it does not
support reading from '-')

Using error_is_set(errp) that way can sweep programming errors under
the carpet when we get called incorrectly with an error set.
Commit 24d3bd6 added a broken error path to iscsi_do_inquiry(): it
first calls error_setg(), then jumps to the preexisting error label,
where error_setg() gets called again, triggering an assertion failure.
Commit cbee81f fixed this by guarding the second error_setg() with an
error_is_set().
Replace this fix by a simpler and safer one: jump right behind the
second error_setg().

Using error_is_set(ERRP) to find out whether a function failed is
either wrong, fragile, or unnecessarily opaque. It's wrong when ERRP
may be null, because errors go undetected when it is. It's fragile
when proving ERRP non-null involves a non-local argument. Else, it's
unnecessarily opaque (see commit 84d18f0).
The error_is_set(errp) in internal_snapshot_prepare() is merely
fragile, because the caller never passes a null errp argument.
Make the code more robust and more obviously correct: receive the
error in a local variable, then propagate it through the parameter.

error_is_set(&var) is the same as var != NULL, but it takes
whole-program analysis to figure that out. Unnecessarily hard for
optimizers, static checkers, and human readers. Commit 84d18f0 dumbed
it down to obvious, but a few more have crept in since, and
documentation was overlooked. Dumb these down, too.

In 1.7.1 qcow2_create2 reopen the file for flushing without the BDRV_O_NO_BACKING
flags.
As a consequence the code would recursively open the whole backing chain.
These three stack arrays would pile up through the recursion and lead to a coroutine
stack overflow.
Convert these array to malloced buffers in order to streamline the coroutine
footprint.
Symptoms where freezes or segfaults on production machines while taking QMP externals
snapshots. The overflow disturbed coroutine switching.

Currently it is very easy to crash QEMU by issuing an object-add command
using an abstract class or a class that doesn't support
TYPE_USER_CREATABLE as parameter.
Example: with the following QMP command:
(QEMU) object-add qom-type=cpu id=foo
QEMU aborts at:
ERROR:qom/object.c:335:object_initialize_with_type: assertion failed: (type->abstract == false)
This patch moves the check for TYPE_USER_CREATABLE before object_new(),
and adds a check to prevent the code from trying to instantiate abstract
classes.
