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 patchset changes the API for
xstats to use integer identifiers instead of strings and implements
this new API for the ixgbe, i40e, e1000, fm10k, and virtio drivers.

v3 changes:
* Corrected ixgbe vf xstats fetching
* Added xstats changes to e1000, f10k, and virtio drivers
* Added cleanup patch that removes now-redundant name field
* Removed ethtool xstats command 
* Removed unused .xstats_count from eth-dev_ops
* Changed test-pmd & proc_info to use new API
* Added documentation update
* Added missing changes to .map file (affected shared lib builds)

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
