Update for RDMA io engine's compatibility
Since the RDMA engine is not able to be successfully compiled, this
patch accommodates it to the upstream version of fio.

Fix compile of RDMA engine for SunOS 5.x
- byteswap.h include that doesn't exist there. Kill it, we
have no use for it.
- No RLIMIT_MEMLOCK on SunOS. The use in the engine is a bit
suspect, so not a problem if we don't have it. Add configure
check for that.

rdma ioengine improvement
1) Use fio shipped reentrant and thread-safe rand to replace buggy rand().
2) Add a pause time period before client start committing IOs.
In SEND/RECV test, it's a good practice to setup the iodepth of
of the RECV side deeper than that of the SEND side to
avoid RNR (receiver not ready) error. The
SEND side may send so many unsolicited message before
RECV side commits sufficient recv buffers into recv queue.
This may lead to RNR error. Here, SEND side pauses for a while
during which RECV side commits sufficient recv buffers.
3) Fix server thread hanging bug.
For RDMA WRITE/READ test, No IO bytes are accumulated in server side
during test. Server thread indicates its task completion by changing
its state into `done' as an alternitive. Add `td->done' checking in
do_io().
4) Some comments revision.
export EXTFLAGS and EXTLIBS with '+=".
explanation on exchanging steps of RDMA ioengine control messages.
All these changes are tested in 40Gbps RoCE and 56Gbps InfiniBand testbeds.

rdma engine graceful teardown
For rdma ioengine's one side operation, RDMA_WRITE or RDMA_READ,
server side gets a message from client side that the task is finished.
In previous version, the server simply exit() in td_io_commit() which
causes segmentation fault in thread mode or process hanging in process
mode. This patch achieves graceful tear down by setting up `td->done`
as UDP engine did.

RDMA IO engine
I have hacked an rdma ioengine based on OFED for fio which could test
both rdma memory semantic (rdma_write/rdma_read) and channel semantic
(send/recv). Would you like to merge this engine into fio?
notes
1) RDMA engine works in IB, iWarp and RoCE.
2) RDMA engine is disable by default. To enable it, execute the following
before compile:
$ export EXTFLAGS="-DFIO_HAVE_RDMA"
$ export EXTLIBS="-libverbs -lrdmacm"
