This patch fixes a number of vcpu related issues.
1. xm vcpu-list now shows info for all vcpus by using
info['max_vcpu_id']+1 as end of the range to query
vcpu_info.
2. Add new vcpu fields, online_vcpus, max_vcpu_id to
XendDomainInfo.sxpr()
3. Remove filter_cpump() which isn't needed now that
the per vcpu cpumap field is correct.
4. Update xm/main.py to use online_vcpus as the number
vcpus to display in list.
