allow hypervisor CPUID bit to be overriden

KVM defaults to the hypervisor CPUID bit to be set, whereas pure
QEMU clears it. On some occasions one wants to set or clear it the
other way round (for instance to get HyperV running inside a guest).

Move the bit-set to be done before the command line parsing and...

introduce -cpu host target

Although the guest's CPUID bits can be controlled in a fine grained way
in QEMU, a simple way to inject the host CPU is missing. This is handy
for KVM desktop virtualization, where one wants the guest to support the
full host feature set....

Handle init/sipi in a main cpu exec loop. (v2)

This should fix compilation problem in case of CONFIG_USER_ONLY.

Currently INIT/SIPI is handled in the context of CPU that sends IPI.
This patch changes this to handle them like all other events in a main
cpu exec loop. When KVM will gain thread per vcpu capability it will...

allow CPUID vendor override

KVM-enabled QEMU will always report the vendor ID of the physical CPU it is
running on. Allow to override this if explicitly requested on the
command line. It will not suffice to name a CPU type (like -cpu phenom),
but you have to explicitly set the vendor: -cpu phenom,vendor=AuthenticAMD...

QEMU KVM: i386: Fix the cpu reset state

As per the IA32 processor manual, the accessed bit is set to 1 in the
processor state after reset. qemu pc cpu_reset code was missing this
accessed bit setting.

kvm: x86: Save/restore KVM-specific CPU states

Save and restore all so far neglected KVM-specific CPU states. Handling
the TSC stabilizes migration in KVM mode. The interrupt_bitmap and
mp_state are currently unused, but will become relevant for in-kernel...

kvm: Add missing bits to support live migration

This patch adds the missing hooks to allow live migration in KVM mode.
It adds proper synchronization before/after saving/restoring the VCPU
states (note: PPC is untested), hooks into
cpu_physical_memory_set_dirty_tracking() to enable dirty memory logging...

Convert machine registration to use module init functions

This cleans up quite a lot of #ifdefs, extern variables, and other ugliness.
