dev: hide driver object

Make rte_driver opaque for non internal users.
This will make extending this object possible without breaking the ABI.

Introduce a new driver header and move rte_driver definition.
Update drivers and library to use the internal header.

Some applications may have been dereferencing rte_driver objects, mark
this object's accessors as stable.

Add support for grouping SW stats together. When stats are
grouped the corresponding stats values for each queue
are obtained during calling one read callback. This is useful
to group per-queue stats 'packets' and 'bytes' to keep stats
consistent, i.e. a number of bytes corresponds to a number of
packets. These stats will be added in the following patches.
