tcg: Optionally sign-extend 32-bit arguments for 64-bit hosts.

Some hosts (amd64, ia64) have an ABI that ignores the high bits
of the 64-bit register when passing 32-bit arguments. Others
require the value to be properly sign-extended for the type.
I.e. "int32_t" must be sign-extended and "uint32_t" must be...

target-i386: fix decoding of negative 4-byte displacements

Negative four byte displacements need to be sign-extended after
c086b783eb7a578993d6d2ab62c4c2666800b63d. Do so.

resent: x86/cpuid: Add kvm32 CPU model

Create a kvm32 CPU model that describes a least common denominator
for KVM capable guest CPUs. Useful for migration purposes.

kvm: fix 80000001.EDX supported bit filtering

On AMD some bits from 1.EDX are reported in 80000001.EDX. The mask used
to copy bits from 1.EDX to 80000001.EDX is incorrect resulting in
unsupported features passed into a guest.

Do not stop VM if emulation failed in userspace.

Continue vcpu execution in case emulation failure happened while vcpu
was in userspace. In this case #UD will be injected into the guest
allowing guest OS to kill offending process and continue.

kvm: validate context for kvm cpu get/put operations

kvm: allow qemu to set EPT identity mapping address

If we use larger BIOS image than current 256KB, we would need move reserved
TSS and EPT identity mapping pages. Currently TSS support this, but not
EPT.
