> The allocation functions take a alignment argument that can be useful to hint
> the compiler optimizer. This is supported by GCC and Clang but only useful with
> GCC because Clang gives warning if alignment is 0.
> 
> Newer versions of GCC have a malloc attribute that can be used to find
> mismatches between allocation and free; the typical problem caught is a
> pointer allocated with rte_malloc() that is then incorrectly freed using free().
> The name of the DPDK wrapper macros for these attributes are chosen to be
> similar to what GLIBC is using in cdefs.h.
> Note: The rte_free function prototype was moved ahead of the allocation
> functions since the dealloc attribute now refers to it.
