Adds common code for collecting basic statistics used by many
SW based PMD's such as af_packet, af_xdp, null, tap and ring.
This version uses std atomic on all platforms. The memory order
is chosen to be the best performance but still providing the
guarantees expected of PMD counters.
By using common code, it also fixes missing counts in several drivers.
And fixes several bugs.
v7 - use stdatomic even on 64 bit. Does cause extra locked operation
for increment on x86 64 but will be safe.
- rebase
