This patch adds a "struct numa_guest_info" to libxc, which allows to 
specify a guest's NUMA topology along with the appropriate host binding.
Here the information will be filled out by the Python wrapper (I left 
out the libxl part for now), it will fill up the struct with sensible 
default values (equal distribution), only the number of guest nodes 
should be specified by the caller. The information is passed on to the 
hvm_info_table. The respective memory allocation is in another patch.
