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.

1f37cb2bb4 bus/pci: make driver-only headers private
The pci bus interface is for drivers only.
Mark as internal and move the header in the driver headers list.

While at it, cleanup the code:
- fix indentation,
- remove unneeded reference to bus specific singleton object,
- remove unneeded list head structure type,
- reorder the definitions and macro manipulating the bus singleton object,
- remove inclusion of rte_bus.h and fix the code that relied on implicit
  inclusion,

5729407fa4 net/virtio: unmap PCI device in secondary process
In multi-process, the secondary process will remap PCI during
initialization, but the mapping is not removed in the uninit path,
the device is not closed, and the device busy error will be reported
when the device is hotplugged.

This patch unmaps PCI device at secondary process uninitialization
based on virtio_rempa_pci.

aa0d4b8a01 net/virtio: fix secondary process crash with PCI devices
The Virtio rework series mistakenly moved the rte_pci_device
pointer to struct virtio_hw, which is shared between the two
processes. But this structure is per-process, so this change
made secondary process to try accessing primary process-only
memory, leading to a crash.

This patch reverts to proper behavior, by storing the
rte_pci_device pointer into the per-process
virtio_pci_internal struct. It also provides helper to get
the pointer from the virtio_hw struct pointer.

b93c3530c1 net/virtio: fix PCI ops assignment
VIRTIO_OPS() macro relies on the port ID stored in the
virtio_hw struct. Issue is that it is used before being
assigned at init time. It results in all devices setting
ops on port ID 0, causing crash later when calling ops
for port IDs other than 0.

This patch ensures port ID assignment is done at early
primary process probe time, before it is being used.
