Until now, when we connect gdb to the QEMU gdb-server, the single-step mode is not managed. This patch adds this, only for kvm-pr: If KVM_GUESTDBG_SINGLESTEP is set, we enable single-step trace bit in the MSR (MSR_SE) just before the __kvmppc_vcpu_run(), and disable it just after. In kvmppc_handle_exit_pr, instead of routing the interrupt to the guest, we return to host, with KVM_EXIT_DEBUG reason.
