This change include several changes as listed below all related to UAR.
UAR is a special PCI memory area where the so-called doorbell register and
blue flame register live. Blue flame is a feature for sending small packets
more efficiently via a PCI memory page, instead of using PCI DMA.
- All structures and functions named xxx_uuars were renamed into xxx_bfreg.
- Remove partially implemented Blueflame support from mlx5en(4) and mlx5ib.
- Implement blue flame register allocator.
- Use blue flame register allocator in mlx5ib.
- A common UAR page is now allocated by the core to support doorbell register
writes for all of mlx5en and mlx5ib, instead of allocating one UAR per
sendqueue.
- Add support for DEVX query UAR.
- Add support for 4K UAR for libmlx5.

Make completion event path mostly lockless using EPOCH(9).
Implement a mechanism using EPOCH(9) which allows us to make
the callback path for completion events mostly lockless.
Simplify draining callback events using epoch_wait().
While at it make sure all receive completion callbacks are
covered by the network EPOCH(9), because this is required
when calling if_input() and ether_input() after r357012.

from Mellanox Technologies. The current driver supports ethernet
speeds up to and including 100 GBit/s. Infiniband support will be
done later.
The code added is not compiled by default, which will be done by a
separate commit.
