Either of the two cpumap can be NULL, in which case, only the affinity corresponding to the non-NULL cpumap will be affected. Getting soft affinity happens indirectly (see, e.g., `xl vcpu-list'), as it is already for hard affinity). This commit also introduces some logic to check whether the affinity which will be used by Xen to schedule the vCPU(s) does actually match with the cpumaps provided. In fact, we want to allow every possible combination of hard and soft affinity to be set, but we warn the user upon particularly weird situations (e.g., hard and soft being disjoint sets of pCPUs). This very change also update the error handling for calls to libxl_set_vcpuaffinity() in xl, as that can now be any libxl error code, not just only -1.
