Add a new field to the rte_ring structure to store the memzone pointer which
contains the ring. For rings created using rte_ring_create(), the field will
be set automatically.
This new field will allow users of the ring to query the numa node a ring is
allocated on, or to get the physical address of the ring, if so needed.
The rte_ring structure will also maintain ABI compatibility, as the
structure members, after the new one, are set to be cache line aligned,

Due to eal_alarm_callback() and rte_eal_alarm_set() use gettimeofday()
to get the current time, and gettimeofday() is affected by jumps.
For example, set up a rte_alarm which will be triggerd next second (
current time + 1 second) by rte_eal_alarm_set(). And the callback
function of this rte_alarm sets up another rte_alarm which will be
triggered next second (current time + 2 second).
Once we change the system time when the callback function is triggered,
it is possible that rte alarm functionalities work out of expectation.
Replace gettimeofday() with clock_gettime(CLOCK_MONOTONIC_RAW, &now)
could avoid this phenomenon.

eventfd_t is defined for the second arg(value), but not for fd.
