John Baldwin 774a662063 OFED: Various changes from Linux 4.12 
Most of the changes involve renaming InfiBand address handles (AH) to
RDMA address handles including renaming various types and functions.
Address handles now also include type-specific fields and a set of
wrapper accessor functions for getting and setting fields.  For some
of the type and function renames, drivers in sys/dev had to be updated
directly (typically via sed).

This contains changes from the following Linux commits:

f039f44fc331 IB/core: Add support for draining IB_POLL_DIRECT completion queues
fedd9e1f7582 IB/cq: Don't process more than the given budget

0008b84ea9af IB/umem: Add support to huge ODP
3e7e1193e28a IB: Replace ib_umem page_size by page_shift
cb8637660ae8 IB/SA: Move functions update_sm_ah() and ib_sa_event()

cfd519358f50 IB/IPoIB: Remove 'else' when the 'if' has a return.
82ffc226483c IB/CM: Add braces when using sizeof
dfa834e1d97e IB/SA: Introduce path record specific types
c2f8fc4ec440 IB/SA: Rename ib_sa_path_rec to sa_path_rec
9fdca4da4d8c IB/SA: Split struct sa_path_rec based on IB and ROCE specific fields
4c33bd1926cc IB/SA: Add support to query OPA path records
57520751445b IB/SA: Add OPA path record type
87f0faadc685 IB/SA: Add OPA addr header
eed7624552ca RDMA/mlx4: Fix MAD tunneling when SRIOV is enabled
f937d93a9122 RDMA/uverbs: Declare local function static and add brackets to sizeof

The IPoIB portions of ee1c60b1bff8 were already present in FreeBSD
from an earlier sync with OFED.  Likewise, the ib_uverbs_cmd.c
changes from 4ba66093bdc6 were also already present.
