sort: new --human-numeric-sort option to sort KiB MB etc.
* NEWS: Document the new option * doc/coreutils.texi (sort invocation): ditto * src/sort.c (main): handle the new --human-numeric-sort option (-h). (human_numcompare): A new function to compare SI and IEC suffixes before falling back to the standard --numeric comparison. (find_unit_order): A new helper function to find the order of magnitude of a number string as determined by its suffix. (check_mixed_SI_IEC): A new helper function to exit with error if both SI and IEC suffixes are presented. * tests/misc/sort: Add 8 tests to test the new functionality. * THANKS: Update
