s390x: Prepare cpu.h for emulation

We need to add some more logic to the CPU description to leverage emulation
of an s390x CPU. This patch adds all the required helpers, fields in CPUState
and constant definitions required for user and system emulation.

s390x: fix KVM target

During Jan's rework of the generic KVM layer, he added some more error checks
and actually aborted if something went wrong. Unfortunately, one of the s390
internal error codes slipped through, aborting the VM without needing to.

This patch fixes booting of S390x virtual machines in KVM....

kvm: Align kvm_arch_handle_exit to kvm_cpu_exec changes

Make the return code of kvm_arch_handle_exit directly usable for
kvm_cpu_exec. This is straightforward for x86 and ppc, just s390
would require more work. Avoid this for now by pushing the return code...

inline cpu_halted into sole caller

All implementations are now the same, and there is only one caller,
so inline the function there.

always qemu_cpu_kick after unhalting a cpu

This ensures env->halt_cond is broadcast, and the loop in
qemu_tcg_wait_io_event and qemu_kvm_wait_io_event is exited
naturally rather than through a timeout.

kvm: Drop return values from kvm_arch_pre/post_run

We do not check them, and the only arch with non-empty implementations
always returns 0 (this is also true for qemu-kvm).

kvm: Provide sigbus services arch-independently

Provide arch-independent kvm_on_sigbus* stubs to remove the #ifdef'ery
from cpus.c. This patch also fixes --disable-kvm build by providing the
missing kvm_on_sigbus_vcpu kvm-stub.

Delete useless 'extern' qualifiers for functions

them.
