Add QEMUD_CMD_FLAG_NET_NAME to indicate that '-net ...,name=foo' is
supported and QEMUD_CMD_FLAG_HOST_NET_ADD to indicate that the
'host_net_add' monitor command is available.

Set both these flags if the qemu version is greater than 0.10.0.
Checking via the '-help' output would not work for the monitor command
and even for the command line arg, it would be quite fragile.

* src/qemu_conf.h: add new flags as aliases of QEMUD_CMD_FLAG_0_10

* src/qemu_conf.c: set QEMUD_CMD_FLAG_0_10 for versions >= 0.10.0

* tests/qemuhelptest.c: set QEMUD_CMD_FLAG_0_10 for the appropriate
  qemu versions

Re-factor this code so that it can be used for NIC hotplug
too. The awkward prefix and type_sep arguments are needed to
allow us to do "host_net_add tap vlan=..."

* src/qemu_conf.c: factor the net backend string formatting
  code into its own function

Re-factor this code so that it can be used for NIC hotplug
too. The awkward arguments are needed to allow use to do
"pci_add auto nic macaddr=..."

This is in preparation for a more strict make syntax-check
rule that will detect trailing blank lines.

There are no functional changes in this patch apart from adding the
monitor type to the state XML.

The patch mostly consists of switching to use virDomainChrDef every
where to describe the monitor.

* src/domain_conf.h: replace monitorpath with monitor_chr

* src/domain_conf.c: handle parsing the monitor type and initializing
  monitor chr

* src/qemu_conf.[ch]: make qemudBuildCommandLine take a
  virDomainChrDefPtr and use that to build the -monitor parameter

* src/qemu_driver.c: split pty specific and common code from
  qemudOpenMonitor, have qemudStartVMDaemon() initialize monitor_chr

* tests/qemuxml2argvtest.c: update for qemudBuildCommandLine() change

	* src/qemu_conf.c, src/qemu_conf.h: Use -vga or -std-vga
	when starting guests if video card is present
	* tests/qemuhelptest.c: Change to use constants instead
	of hardcoded hex numbers, and add VGA support
	* tests/qemuxml2argvdata/qemuxml2argv-graphics-sdl-fullscreen.xml,
	tests/qemuxml2argvdata/qemuxml2argv-graphics-sdl.args,

	* tests/qemuxml2argvtest.c: Add QEMUD_CMD_FLAG_VGA flag
	* tests/qemuxml2xmltest.c: Add missing graphics-vnc-sasl/tls tests

* src/qemu_conf.c: when connecting an interface if it reference
  an undefined network, then we used to raise an internal error.

* src/qemu_conf.c: patch from C.J. Adams-Collier adding support
  for arm emulation if qemu-system-arm is present

Rather than numerous instances of:

emulator = vm->def->emulator;
if (!emulator)
    emulator = virDomainDefDefaultEmulator(conn, vm->def, driver->caps);
if (!emulator)
    return -1;

Set this value at XML parse time in the domain config, so we can depend on
it for all future emulator accesses. There were unchecked accesses in the
qemu driver that were tripping up on this if no emulator was specified in
the XML, see:

http://www.redhat.com/archives/libvir-list/2008-October/msg00602.html

Certain drivers always need an 'emulator' specified in the XML (qemu and lxc
at least). Store this info in capabilities.

We will eventually use this to move default emulator handling out of
drivers and into domain_conf.*

Qemu < 0.10.0 did not support it, and virt-* tools now try to add this by
default, so it's extra important we ensure the option exists.

New function qemudParseHelpStr was being called with arguments in the
wrong order, so command flags == kvm_version :/

The KVM version string can be one of the following:

  - qemu-kvm-x.y.z in stable releases
  - kvm-XX for kvm versions up to kvm-85
  - qemu-kvm-devel-XX for kvm version kvm-86 and later

There are only a few of places where we need to detect
differences between KVM versions based on 0.9.1:

  1) VNET_HDR introduced in kvm-74

  2) -incoming tcp introduced in kvm-79

  3) -incoming exec introduced in kvm-80

  4) -incoming stdio in all earlier kvm versions

With qemu-kvm-0.10.x, we can now assume that (1) is available
if it's a KVM release, (2) and (3) is always available and
(4) is never available.

So, from now on we should only need to check the qemu version
number and the "is_kvm" flag for detecting feature availability.
We only need the KVM version number for older releases.

This patch is purely re-factoring without any functional changes
to make way for the next patch.

The main thing achieved by the refactoring is that we now have
easier access to the parenthesised string that KVM folks seem
to delight in changing.

virExec will write out the pid of the daemonized process only. Use this
in the QEMU driver, rather than QEMU's pidfile, so we can catch errors we
might miss if the emulator bails early.

Seems like a simple typo - it has been "format=" since the flag
was introduced, but we added it as "fmt=".
