tools: cpupools: Support arbitrary numbers of physical cpus

To be able to support arbitrary numbers of physical cpus it was necessary to
include the size of cpumaps in the xc-interfaces for cpu pools.
These were:
  definition of xc_cpupoolinfo_t
  xc_cpupool_getinfo()
  xc_cpupool_freeinfo()
xc_cpupool_getinfo() and xc_cpupool_freeinfo() are changed to allocate the
needed buffer and return it.
