David Marchand 1acb7f5474 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.
