hw/arm/virt: fix cmdline parsing bug with CPU options and smp > 1
The recently introduced feature that allows 32 bit guests to be
executed under KVM on a 64-bit host incorrectly handles the case
where more than 1 cpu is specified using '-smp N'
For instance, this invocation of qemu
qemu-system-aarch64 -M virt -cpu cortex-a57,aarch64=off -smp 2
produces the following error
qemu-system-aarch64: Expected key=value format, found aarch64
which is caused by the destructive parsing performed by
cpu_common_parse_features(), resulting in subsequent attempts
to parse the CPU option string (for each additional CPU) to fail.
So duplicate the string before parsing it, and free it directly
afterwards.

target-i386: Clean up misuse of qdev_init() in realize method
x86_cpu_apic_realize() calls qdev_init() to realize the APIC.
qdev_init()'s error handling has unwanted side effects: it unparents
the device, and it calls qerror_report_err().
qerror_report_err() is always inappropriate in realize methods,
because it doesn't return the Error object. It either reports the
error to stderr or the human monitor, or it stores it in the QMP
monitor, where it makes the QMP command fail even though the realize
method succeeded.
Fortunately, qdev_init() can't actually fail here, because realize
can't fail for any of the three possible APIC device models.
Clean up by cutting out the qdev_init() middle-man: set property
"realized" directly.

Since commit
c25f53b06eba1575d5d0e92a0132455c97825b83 ("raw: Probe
required direct I/O alignment") QEMU has failed to launch if image files
produce I/O errors.
Previously, QEMU would launch successfully and the guest would see the
errors when attempting I/O.
This is a regression and may prevent multipath I/O inside the guest,
where QEMU must launch and let the guest figure out by itself which
disks are online.
Tweak the alignment probing code in raw-posix.c to explicitly look for
EINVAL on Linux instead of bailing. The kernel refuses misaligned
requests with this error code and other error codes can be ignored.

blkdebug: fix "once" rule
Background:
The blkdebug scripts are currently engineered so that when a debug
event occurs, a prefilter browses a master list of parsed rules for a
certain event and adds them to an "active list" of rules to be used for
the forthcoming action, provided the events and state numbers match.
Then, once the request is received, the last active rule is used to
inject an error if certain parameters match.
This active list is cleared every time the prefilter injects a new
rule for the first time during a debug event.
The "once" rule currently causes the error injection, if it is
triggered, to only clear the active list. This is insufficient for
preventing future injections of the same rule.
Remedy:
This patch /deletes/ the rule from the list that the prefilter
browses, so it is gone for good. In V2, we remove only the rule of
interest from the active list instead of allowing the "once" rule to
clear the entire list of active rules.
Impact:
This affects iotests 026. Several ENOSPC tests that used "once" can
be seen to have output that shows multiple failure messages. After
this patch, the error messages tend to be smaller and less severe, but
the injection can still be seen to be working. I have patched the
expected output to expect the smaller error messages.

qcow2: Helper function for refcount modification
Since refcounts do not always have to be a uint16_t, all refcount blocks
and arrays in memory should not have a specific type (thus they become
pointers to void) and for accessing them, two helper functions are used
(a getter and a setter). Those functions are called indirectly through
function pointers in the BDRVQcowState so they may later be exchanged
for different refcount orders.
With the check and repair functions using this function, the refcount
array they are creating will be in big endian byte order; additionally,
using realloc_refcount_array() makes the size of this refcount array
always cluster-aligned. Both combined allow rebuild_refcount_structure()
to drop the bounce buffer which was used to convert parts of the
refcount array to big endian byte order and store them on disk. Instead,
those parts can now be written directly.

qcow2: Only return status from qcow2_get_refcount
Refcounts can theoretically be of type uint64_t; in order to be able to
represent the full range, qcow2_get_refcount() cannot use a single
variable to represent both all refcount values and also keep some values
reserved for errors.
One solution would be to add an Error pointer parameter to
qcow2_get_refcount(); however, no caller could (currently) pass that
error message, so it would have to be emitted immediately and be
passed to the next caller by returning -EIO or something similar.
Therefore, an Error parameter does not offer any advantages here.
The solution applied by this patch is simpler to use. Because no caller
would be able to pass the error message, they would have to print it and
free it, whereas with this patch the caller only needs to pass the
returned integer (which is often a no-op from the code perspective,
because that integer will be stored in a variable "ret" which will be
returned by the fail path of many callers).
