Qemu creates a default parallel port for you in case you didn't specify
one on the command line.  Right now this is tied to the '-parallel
<chardev>' command line switch, which in turn causes trouble if you are
creating your parallel port via '-device isa-parallel,<props>'.

This patch adds a variable default_parallel which says whenever a default
parallel port should be added.  It is enabled by default.  It is cleared
when qemu finds '-parallel' or '-device isa-parallel' on the command line.

Qemu creates a default serial line for you in case you didn't specify
one on the command line.  Right now this is tied to the '-serial
<chardev>' command line switch, which in turn causes trouble if you are
creating your serial line via '-device isa-serial,<props>'.

This patch adds a variable default_serial which says whenever a default
serial line should be added.  It is enabled by default.  It is cleared
when qemu finds '-serial' or '-device isa-serial' on the command line.

Part of the patch is some infrastructure for the '-device $driver'
checking (default_driver_check function) which will also be used by the
other patches of this series.

Make the 'vc' chardev backend print a title line with the chardev name
after initialization, using CharDriverState->label.

This patch adds infrastructure and command line option for setting
global defaults for device properties, i.e. you can for example use

  -global virtio-blk-pci.vectors=0

to turn off msi by default for all virtio block devices.  The config
file syntax is:

[global]
  driver = "virtio-blk-pci"
  property = "vectors"
  value = "0"

This can also be used to set properties for devices which are not
created via -device but implicitly via machine init, i.e.

  -global isa-fdc,driveA=<name>

This patch uses the mechanism which configures properties for the
compatibility machine types (pc-0.10 & friends).  The command line
takes precedence over the machine type values.

As KVM now makes use of exception_index to keep pending exceptions, we
have to save&restore this field as well.

NOTE: We have to nail the arch-independent exception_index down to a
certain bit width for proper vmstate processing, namely to 32 bit.

Device names with whitespace require quoting in the shell and in the
monitor.  Some of the offenders are also overly long.  Some have a
more convenient alias, some don't.

The place for verbose device names is DeviceInfo member desc.  The
name should be short & sweet.

On hosts without high-res timers it is impossible to inject rtc interrupt
faster then 1kHz. Windows sometimes configures RTC to generate 1kHz
interrupts, so we can't inject missed interrupts when running on such
hosts. Always injecting an interrupt on REG_C read is also not an option
since Windows wait for REG_C to become zero with interrupt disabled
during boot. This patch uses mixed approach: accelerate timer + inject
up to 1000 interrupts on REG_C read.

migrating between hosts which have different features
might break silently, if the migration destination
does not support some features supported by source.

Prevent this from happening by comparing acked feature

qemu_malloc() does not allow size=0 to be passed in and aborts on this behavior.

Unfortunately, there is good reason to believe that within qemu, there are a
number of, so far, undetected places that assume size=0 can be safely passed.
Since we do not want to abort unnecessarily in production builds, return
qemu_malloc(1) whenever the version file indicates that this is a production
build.
