  chardev: add pty chardev support to chardev-add (qmp)
  chardev: add socket chardev support to chardev-add (qmp)
  chardev: add parallel chardev support to chardev-add (qmp)
  chardev: add serial chardev support to chardev-add (qmp)
  chardev: add file chardev support to chardev-add (qmp)
  chardev: add hmp hotplug commands
  chardev: add qmp hotplug commands, with null chardev support
  chardev: reduce chardev ifdef mess a bit
  chardev: fix QemuOpts lifecycle
  chardev: add error reporting for qemu_chr_new_from_opts

The version.o file did not appear explicitly as a dependency, and
this caused clean builds to fail.  Force its build by making the
Makefile depend on version.o.

(We cannot add it to libqemuutil.a, because it doesn't export any
symbol and thus would not be pulled by the linker).

Exercise all four commands of the TMP105, testing for an issue in the

An early length postincrement in the TMP105's I2C TX path led to
transfers of more than one byte to place the second byte in the third
byte's place within the buffer and the third byte to get discarded.

Fix this by explictly incrementing the length after the checks but
before the callback is called, which again checks the length.

Adjust the Coding Style while at it.

qemu_chr_open_socket is split into two functions.  All initialization
after creating the socket file handler is split away into the new
qemu_chr_open_socket_fd function.

chr->filename doesn't get filled from QemuOpts any more.  Qemu gathers
the information using getsockname and getnameinfo instead.  This way it
will also work correctly for file handles passed via file descriptor
passing.

Finally qmp_chardev_open_socket() is the actual qmp hotplug
implementation which basically just calls socket_listen or
socket_connect and the new qemu_chr_open_socket_fd function.

Introduce the QOM realizefn suggested by Anthony.
Detailed documentation is supplied in the qdev header.

For now this implements a default DeviceClass::realize callback that
just wraps DeviceClass::init, which it deprecates.

DeviceClass::init is to be removed.

Whether the device was initialized or not is QOM-level information and
currently unused. Drop it from device. This leaves the boolean state of
whether or not DeviceClass::init was called or not, a.k.a. "realized".

This patch removes the default boot order for pseries machine. This allows
the machine to handle a NULL boot order in case no -boot option is provided.
Thus it helps SLOF firmware to verify if boot order is specified in command
line or not. If no boot order is provided SLOF tries to boot from the
device set in the nvram.

This patch makes default boot order machine specific instead of
set globally. The default boot order can be set per machine in
QEMUMachine boot_order. This also allows a machine to receive a
NULL boot order when -boot isn't used and take an appropriate action
accordingly. This helps machine boots from the devices as set in
guest's non-volatile memory location in case no boot order is
provided by the user.
