David Marchand a04322f616 bus: hide bus object 
Make rte_bus opaque for non internal users.
This will make extending this object possible without breaking the ABI.

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

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