The current extended ethernet statistics fetching involve doing several
string operations, which causes performance issues if there are lots of
statistics and/or network interfaces. This RFC patchset changes the API
for xstats to use integer identifiers instead of strings and implements
this new API for the ixgbe driver. Others drivers to follow.

v2 changes:
* Fetching xstats count now seperate API function
* Added #define constants for some magic numbers
* Fixed bug with virtual function count fetching
* For non-xstats-supporting drivers, queue stats returned
* Some refactoring/cleanups
* Removed index assumption from example
