General:
--------
- Add API to register external threads

Vhost-user library:
-------------------
- Advertise REPLY_ACK protocol feature unconditionally
 * Previously depending on RTE_VHOST_USER_IOMMU_SUPPORT registration
   flag
 * REPLY_ACK is necessary to ensure proper Vhost-user master/slave
   synchronization
 * Compatibility with old Qemu versions (v2.7 to v2.9.0) will be broken
   when multi-queue enabled. These old Qemu versions have not been
   maintained for years both upstream and in major distributions

- Add support for SET_STATUS protocol feature

- Rework vDPA API for better integration in DPDK class model
 * Target is to remove experimental tag in v20.11

Virtio PMD:
-----------

- Add support for GET/SET_PROTOCOL_FEATURES protocol requests to
  Virtio-user PMD

- Add support for REPLY_ACK protocol feature to Virtio-user PMD

- Add support for SET_STATUS protocol request to Virtio-user PMD
