add support for Arm MTE memory tagging
...
- tag slab allocations with [1..14] tags
- tag freed slab allocations with the "15" tag value to detect accesses to freed slab memory
- when generating tag value for a slab slot, always exclude most recent tag value for that slot
(to make use-after-free detection more reliable) and most recent tag values of its immediate
neighbors (to detect linear overflows and underflows)

clean up includes and remove non-portable includes
...
This marginally increases the portability of hardened_malloc,
eg. on OSX.
