Dennis Dalessandro 38ce2c6f3a IB/rdmavt: Add pkey support
Add pkey table in rdi per port data structure. Also bring in related pkey
functions. Drivers will still be responsible for allocating and
maintaining the pkey table. However they need to tell rdmavt where to find
the pkey table. We can not move the pkey table up into rdmavt because
drivers need to manipulate this long before registering with it.

Add table init as well as teardown for handling qpn maps. Drivers can still

Dennis Dalessandro b4e64397da IB/rdmavt: Break rdma_vt main include header file up
Until all functionality is moved over to rdmavt drivers still need to
access a number of fields in data structures that are predominantly
meant to be used by rdmavt. Once these rdmavt_<ibta_object>.h header
files are no longer being touched by drivers their content should be
moved to rdmavt/<ibta_object>.h. While here move a couple #defines
over to more general IB verbs header files because they fit better.

Dennis Dalessandro f3d01bbcdc IB/rdmavt: Add an ibport data structure to rdmavt
Converge the ibport data structures of qib and hfi1 into a common ib
port structure. Also provides a place to keep track of these ports
in case rdmavt needs it. Along with this goes an attach and detach
function for drivers to use to notify rdmavt of the ports.

Dennis Dalessandro 0194621b22 IB/rdmavt: Create module framework and handle driver registration
This patch introduces the basics for a new module called rdma_vt. This new
driver is a software implementation of the InfiniBand verbs and aims to
replace the multiple implementations that exist and duplicate each others'
code.

While the call to actually register the device with the IB core happens in
rdma_vt, most of the work is still done in the drivers themselves. This
will be changing in a follow on patch this is just laying the groundwork
for this infrastructure.
