Gleb Natapov 66fd3f7f90 KVM: Do not re-execute INTn instruction. 
Re-inject event instead. This is what Intel suggest. Also use correct
instruction length when re-injecting soft fault/interrupt.

Gleb Natapov 923c61bbc6 KVM: Remove irq_pending bitmap 
Only one interrupt vector can be injected from userspace irqchip at
any given time so no need to store it in a bitmap. Put it into interrupt
queue directly.

Avi Kivity 937a7eaef9 KVM: Add a pending interrupt queue

accepted by the virtual processor core but not yet injected.

Avi Kivity 26eef70c3e KVM: Clear exception queue before emulating an instruction 
If we're emulating an instruction, either it will succeed, in which case
any previously queued exception will be spurious, or we will requeue the
same exception.
