+5992. [func] Introduce the new isc_mem_*x() APIs that takes extra
+ flags as the last argument. Currently ISC_MEM_ZERO
+ and ISC_MEM_ALIGN(n) flags have been implemented that
+ clears the memory to avoid the isc_mem_get()/memset()
+ pattern and make aligned allocation which replaces the
+ previous isc_mem_*_aligned() calls. [GL !6398]
