c752998b5e pci: introduce library and driver
The PCI lib defines the types and methods allowing to use PCI elements.

The PCI bus implements a bus driver for PCI devices by constructing
rte_bus elements using the PCI lib.

Move the relevant code out of the EAL to its expected place.

Libraries, drivers, unit tests and applications are updated to use the
new rte_bus_pci.h header when necessary.

00a3d8104a ethdev: remove detachable device flag
This flag is not necessary at the ether layer anymore.
Buses are able to advertise their hotplug support. The ether layer can
rely upon this capability instead of a special flag.

d5b0924ba6 ethdev: add return value to stats get dev op
The stats_get dev op API doesn't include return value, so PMD cannot
return an error in case of failure at stats getting process time.

Since PCI devices can be removed and there is a time between the
physical removal to the RMV interrupt, the user may get invalid stats
without any indication.

This patch changes the stats_get API return value to be int instead of
void.

All the net PMDs stats_get dev ops are adjusted by this patch.
