Arm CQ early enough in pingpong examples
The example pingpong programs have a race when using events where the
client sends the first packet but the server hasn't yet armed the CQ
by calling ibv_req_notify_cq() thus waiting forever in
ibv_get_cq_event(). The fix is to move the call to
ibv_req_notify_cq() before signaling the client to "start".

Handle devices that don't support SRQ
create_srq is not a mandatory device function, therefore in
userspace/libibverbs/src/verbs.c ibv_create_srq should check
create_srq() first before calling it, otherwise the caller will cause
the segmentation fault on device which doesn't support SRQs.

Handle out-of-order completions in pingpong examples
Keep track of whether send and/or receive is pending in libibverbs
pingpong examples. This avoids failures when the remote side receives
data and posts a send very quickly, and the local side completes the
receive before the previous send. With the old code, this could
result in posting a send before the previous send completed, and
therefore overrun the send queue.

Update for new kernel ABI (stale event handling)
Update to handle new kernel ABI for avoiding stale asynchronous
events. When a CQ, QP or SRQ is destroyed, the kernel reports the
number of events it has given to userspace, and we wait until we've
handled the same number of events.
This does introduce a library API change: consumers are now required
to call ibv_put_async_event() to release every asynchronous event that
they retrieve via ibv_get_async_event().
