This patch adds an errp parameter to bdrv_new() and updates all its
callers. The next patches will make use of this in order to check for
duplicate IDs. Most of the callers know that their ID is fine, so they
can simply assert that there is no error.
Behaviour doesn't change with this patch yet as bdrv_new() doesn't
actually assign errors to errp.

Near total rewrite of this device model. It is stylistically
obsolete, has numerous coverity fails and is not up to date with latest
Xilinx documentation. Fix.
The registers are flattened into a single array. This greatly simplifies
the MMIO accessor functions.
We take the oppurtunity to update the register Macro definitions to
match the latest TRM. Xilinx has de-documented some regs hence there are
some straight deletions. We only do this however in the case or a stock
read-as-written reset-zero register. Non-zero resets are always
preserved. New register definitions are added as needed.
This all comes with a VMSD version break as the union layout from before
was a bit strange and we are better off without it.

When VM guest programs multicast addresses for
a virtio net card, it supplies a 32 bit
entries counter for the number of addresses.
These addresses are read into tail portion of
a fixed macs array which has size MAC_TABLE_ENTRIES,
at offset equal to in_use.
To avoid overflow of this array by guest, qemu attempts
to test the size as follows:
- if (in_use + mac_data.entries <= MAC_TABLE_ENTRIES) {
however, as mac_data.entries is uint32_t, this sum
can overflow, e.g. if in_use is 1 and mac_data.entries
is 0xffffffff then in_use + mac_data.entries will be 0.
Qemu will then read guest supplied buffer into this
memory, overflowing buffer on heap.

The raven_io_read() and raven_io_write() functions pass and
return values in little-endian format (since the IO op struct
is marked DEVICE_LITTLE_ENDIAN); however they were storing the
values in the buffer to pass to address_space_read/write()
in host-endian order, which meant that on big-endian hosts
the values were inadvertently reversed. Use the *_le_p()
accessors instead so that we are consistent regardless of
host endianness.
Strictly speaking the byte order of the buffer for
address_space_rw() is target byte order (which for PPC
will be BE) but it doesn't actually matter as long as we
are consistent about the marking on the IO op struct and
which stl_*_p().
This bug was probably introduced due to confusion caused by
the two different versions of ldl_p() and friends:
bswap.h defines versions meaning "host endianness access"
cpu-all.h defines versions meaning "target endianness access"
As a target-independent source file prep.c gets the bswap.h
versions; the very similar looking code in ioport.c is
compiled per-target and gets the cpu-all.h versions.

There are 3 different variants of the decrementor for BookE and BookS.
The BookE variant sets TSR[DIS] to 1 when the DEC value becomes 1 or 0. TSR[DIS]
is then the indicator whether the decrementor interrupt line is asserted or not.
The old BookS variant treats DEC as an edge interrupt that gets triggered when
the DEC value's top bit turns 1 from 0.
The new BookS variant maintains the assertion bit inside DEC itself. Whenever
the DEC value becomes negative (top bit set) the DEC interrupt line is asserted.
So far we implemented mostly the old BookS variant. Let's do them all properly.

Before IOThread was its own object, each virtio-blk device would create
its own internal thread. We need to preserve this behavior for
backwards compatibility when users do not specify -device
virtio-blk-pci,iothread=<id>.
This patch changes how the internal IOThread object is created.
Previously we used the monitor object_add() function, which is really a
layering violation. The problem is that this needs to assign a name but
we don't have a name for this internal object.
Generating names for internal objects is a pain but even worse is that
they may collide with user-defined names.
Paolo Bonzini <pbonzini@redhat.com> suggested that the internal IOThread
object should not be named. This way the conflict cannot happen and we
no longer need object_add().
One gotcha is that internal IOThread objects will not be listed by the
query-iothreads command since they are not named. This is okay though
because query-iothreads is new and the internal IOThread is just for
backwards compatibility. New users should explicitly define IOThread
objects.

Right now, the temperature property must be written in milli-celsius,
but it reads back the value in 8.8 fixed point. Fix this by letting the
property read back the original value (possibly rounded). Also simplify
the code that does the conversion.
Before:
(QEMU) qom-set path=/machine/peripheral/sensor property=temperature value=20000
{u'return': {}}
(QEMU) qom-get path=sensor property=temperature
{u'return': 5120}
After:
(QEMU) qom-set path=/machine/peripheral/sensor property=temperature value=20000
{u'return': {}}
(QEMU) qom-get path=sensor property=temperature
{u'return': 20000}

It may not be sensible for normal use cases, but it allows to use
/dev/null in QTest.
