* Add a file containing useful macro definitions, currently a single top-level macro for obtaining the size of an array; use it to replace a sizeof(x) / sizeof(x[0]) construct in system/smbus.c . This requires switching the GCC build mode from C11 to C11 with GCC extensions. * Initial NUMA awareness (#12) support: parse the ACPI SRAT to build up new internal structures related to proximity domains and affinity; use these structures in setup_vm_map() and calculate_chunk() to skip the work on the processors which don't belong to the proximity domain currently being tested. Tested on a number of 1S single-domain, 2S multi-domain and 4S multi-domain platforms. SKIP_RANGE(iterations) trick by Martin Whitaker.
