Adds CPU selection infrastructure
Each driver supporting CPU selection must fill in host CPU capabilities.
When filling them, drivers for hypervisors running on the same node as
libvirtd can use cpuNodeData() to obtain raw CPU data. Other drivers,
such as VMware, need to implement their own way of getting such data.
Raw data can be decoded into virCPUDefPtr using cpuDecode() function.
When implementing virConnectCompareCPU(), a hypervisor driver can just
call cpuCompareXML() function with host CPU capabilities.
For each guest for which a driver supports selecting CPU models, it must
set the appropriate feature in guest's capabilities:
Actions needed when a domain is being created depend on whether the
hypervisor understands raw CPU data (currently CPUID for i686, x86_64
architectures) or symbolic names has to be used.
Typical use by hypervisors which prefer CPUID (such as VMware and Xen):
- convert guest CPU configuration from domain's XML into a set of raw
data structures each representing one of the feature policies:

'force' and 'disable' policies turn on/off the feature regardless of its
availability on host. 'force' is unlikely to be used but its there for

the feature but a guest may still try to access it anyway and you don't want
it to succeed.
'optional' policy sets the feature according to its availability on host.
When a guest is booted on a host that has the feature and then migrated to
another host, the policy changes to 'require' as we can't take the feature
away from a running guest.
Default policy for features provided by host CPU but not specified in domain
configuration is set using match attribute of cpu tag. If 'minimum' match is
requested, additional features will be treated as if they were specified
with 'optional' policy. 'exact' match implies 'disable' policy and 'strict'

config can now move out of domain_conf.c and into the
qemu_driver.c where they belong.
* src/conf/capabilities.h: Add callbacks for serializing private
state to/from XML
* src/conf/domain_conf.c, src/conf/domain_conf.h: Remove the
monitor, monitor_chr, monitorWatch, nvcpupids and vcpupids
fields from virDomainObjPtr. Remove code that serialized
those fields
* src/libvirt_private.syms: Export virXPathBoolean
* src/qemu/qemu_driver.c: Add callbacks for serializing monitor
and vcpupid data to/from XML
* src/qemu/qemu_monitor.h, src/qemu/qemu_monitor.c: Pass monitor
char device config into qemuMonitorOpen directly.
Pull code to start CPUs executing out of qemudInitCpuAffinity()
The code to start CPUs executing has nothing todo with CPU
affinity masks, so pull it out of the qemudInitCpuAffinity()
method and up into qemudStartVMDaemon()
* src/qemu/qemu_driver.c: Pull code to start CPUs executing out
of qemudInitCpuAffinity()
Add a 'format' arg to qemuMonitorChangeMedia() since JSON will support it
The current QEMU disk media change does not support setting the
disk format. The new JSON monitor will support this, so add an
extra parameter to pass this info in
* src/qemu/qemu_driver.c: Pass in disk format when changing media
* src/qemu/qemu_monitor.h, src/qemu/qemu_monitor.c,
src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h:
Add a 'format' arg to qemuMonitorChangeMedia()
