Implmented a method for detecting the current netmap driver version.
Once detected, tcpreplay will just deal with it and attempt to satisfy the drivers needs. The behavior of netmap has changed somewhat. It is now possible to simply specify the interface as (for example) "netmap:eth6"
Fix invalid ioctl call - #106
Reverted some changes in main netmap loop to increase performance. - #106
Added 'netmap:foo!' for all queues
By default only write to first queue - other queues are slow
General fixes to interface names.

Note: Should review with Luigi. Under Linux, slots are not seen as available
unless NIOCTXSYNC is run after poll. Also, running NIOCTXSYNC seems to make
things faster. We can just TX as fast as possible, but a rediculously high
number of packets are reported sent (e.g. reports of 500Gbps). To get
accuracy, need to use NIOCTXSYNC.

Also, only queue 0 is fast on Linux. This is the default when using interface
'netmap:foo'. If using all queuse with 'netmap:foo!' we slow down. Sending to
'netmap:foo-0' is faster but not as fast as default. 'netmap:foo-7' is very
slow.
Improved wording on a warning message
