new lightweight open_query/close_query IB extension for fast attribute query
Consumers that need provider attributes must do a full device open
in order to get any provider/device information. With so many static device
entries in /etc/dat.conf consumers are building classification
mechanisms to identify provider type, locality, name, device
mode, and decide which device is appropriate. The existing DAT interface
doesn't provide a lightweight mechanism for queries.
The following fast query functions have been added to dat_ib_extensions.h:
In addition, DAT extension interface, dat_extension_op, has been
expanded to include new internal calls to handle quick provider load
and function linkage via udat_extension_open, and udat_extension_close
functions. Extended operations needing DAT open/close services need
to be defined from a DAT_OPEN_EXTENSION_BASE or DAT_CLOSE_EXTENSION_BASE
respectively.
NOTE: The ia_handle returned with open query must be closed with subsequent
close_query and not used with any other dat_ia_ operations. Attribute
storage from query_open is not valid after close_query call.
The IB extensions have been rolled to version 2.0.8 with this new API.
The changes are backward compatible.

cma: long delays when opening cma provider with no IPoIB configured
The rdma_cm provider (ofa-v2-ib0) can take netdev, ip address, or hostname
for local address bindings. When trying to open a non-existent netdev (ib0)
the provider will fall through and use the getaddrinfo sys call assuming
dat.conf parameter is either an IP address or hostname and not a netdev.
This patch changes getipaddr() error handling when opening the cma provider
on a non-existant netdev. It will only call getaddrinfo with AI_CANONNAME
hints after checking for a valid hostname.

dapltest: Add final send/recv "sync" for transaction tests.
The transaction tests need both sides to send a sync message after running the test. This ensures that all remote operations are complete before dapltest deregeisters memory and disconnects the endpoints.
Without this logic, we see intermittent async errors on iwarp devices because a read response or write arrives after the rmr has been destroyed.
I believe this is more likely to happen with iWARP than IB because iWARP completions only indicate the local buffer can be reused. It doesn't imply that the message has even arrived at the peer, let alone been placed in the peer application's memory.
Changes from V1:
- allocate new send/recv buffers for the Final Sync message.
- post the Final Sync recv buffer at the beginning of the final iteration of a test.
- tests ok on cxgb4 and mlx4 devices.
