examples/l3fwd-power: fix Rx descriptor size

L3fwd power app monitors the RX queues to see if the polling frequency
should be adjusted (the busier the queue, the higher the frequency).
The app uses several thresholds in the ring to determine the frequency,
being 96 the highest one, when frequency should be highest.

The problem is that the difference between this value and the ring size
is not big enough (128 - 96 = 32 descriptors), which means that
if the descriptors are not replenished quick enough, queue might
not be busy, but the app would think that it is, because 96th descriptor
is set.

Therefore, by increasing this gap (increasing the RX ring size),
we make sure that this false measurement will not happen.

examples: fix optind reset

The variable optind should be reset to one not zero.

From the man page:
"The variable optind is the index of the next element to be processed in
argv. The system initializes this value to 1.
The caller can reset it to 1 to restart scanning of the same argv, or when
scanning a new argument vector.”

The problem I saw with my application was trying to parse the wrong
option, which can happen as DPDK parses the first part of the command line
and the application parses the second part. If you call getopt() multiple
times in the same execution, the behavior is not maintained when using
zero for optind.

examples/l3fwd-power: enable one-shot Rx interrupt and polling switch

The patch demonstrates how to handle per rx queue interrupt in a NAPI-like
implementation in userspace. The working thread mainly runs in polling mode
and switch to interrupt mode only if there is no packet received in recent polls.
The working thread returns to polling mode immediately once it receives an
interrupt notification caused by the incoming packets.
The sample keeps running in polling mode if the binding PMD hasn't supported
the rx interrupt yet. Now only ixgbe(pf/vf) and igb support it.
