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.

Add --output-format command line option
Right now we have normal, terse, and json output. Lets add a parameter
that controls how to output results, instead of having options for
both terse and json outputs. If we are going to add a 4th output
type in the future, it's only going to get more messy.

Default to terse version 3
4 will include the trim output, and we'll augment that with json output
as well. To avoid breaking anyone who's using the git pulls for their
testing, we'll default to version 3 for now.

This only works on Linux so far, and it's always sync given what
the interface to the kernel looks like. Also restricted to pure

libaio: use INT_MAX to signal that we don't want the ring buffer
We can't use 0 since the libaio library _also_ checks the
nr_events being passed in. So lets use INT_MAX instead.

libaio: pass in 0 for queue depth if we can
We don't need the user ring, unless the job file specified
that we need it. So tell the kernel. Fall back to passing
in the normal queue depth, if the kernel doesn't support
disabling the user ring.

client: support per-client job files
Currently the fio network client sends all job files to all clients.
This isn't very flexible.
Add support for specifying a specific job file for each client. Example:
$ fio --client hostname1 jobfile1 --client hostname2 jobfile2
would before add jobfile1 and jobfile2 as job files for both clients.
With this change, only jobfile1 is sent to hostname1, and only
jobfile2 is sent to hostname2.

example: add SSD steady state test case
Simple test case:
- Start by filling a drive with large block sequential writes
- Once that is done, start filling it with random 4k writes.
At some point the latter phase will hit steady state. Progress

eta: make CR= display more easy to understand
Currently we sum up read and write IOPS/BW rates, but that reads
a bit strange when a given workload only does reads OR writes.
The user then thinks that fio mis-parsed the setting, reading
twice as much as expected.
Only sum up for the read OR write side if one direction is given.
For a mixed workload, it's still the sum of both.
