Contains the following:
- annotation-aware codes-mapping API
- updated mapping tests
- updated codes-base models to use the new API
- updated LSM to configure based on annotation
  - fixed initialization issue (was doing config as an event)
  - no need for lsm_send_init from outside LPs

- Replay tool no longer offers bglockless prefix (ignored for POSIX
calls).
- Print workload load time on rank 0
- convert sleep functionality to use more accurate nanosleep

Hack to force replay tool to use one preallocated and initialized
I/O buffer for all I/O operations. Malloc'ing a new
(uninitialized) buffer for each I/O operation causes really poor
performance, likely due to page faults.

Darshan generates longer delays, and mpi replay tool now can be
configured to play a percentage of the overall delay.

- currently ugly-looking, might want to think of
  a better way to acheive this

For a particular LP type:
- get the global number of LPs of that type
- get the relative ID w.r.t. LPs of the same type

Darshan and recorder workloads have temporary debug parameters that
are no longer used and can be removed.

The codes-workload-test and codes-workload-mpi-replay both support
the new paramters of the bgp-io language workload generator. Also,
support has been added to the config file and codes-workload-mpi-replay
program for loading the parameters of a darshan config file.

Now, specify the darshan install directory with --with-darshan=/dir/
to build the darshan workload generator and link it with test
applications.

Modifications to autotools to include necessary info for building
the darshan workload API. This API compiles fine, but the mpi replay
test is not linking properly with darshan library.

Improve the performance of the darshan i/o workload by converting the
linked list of per-rank contexts to a hash table.

Update the output directory argument of the mpi-replay tool to just
specify an already existing directory to perform the workload I/O in.

Modify the mpi-replay tool (located at tests/workload) to spit out
verbose information on each event it replays, if user specifies
-v option. Also, modify the mpi-replay tool to perform no-ops for
each replayed event, if user specifies --noop option. The replay
tool should function properly for all workload types now.

TODO: The tool should offer functionality for initializing the context
of the output replay directory. That is, the tool should first scan
the given workload and create all files and preallocate space for all
I/O ops in the workload. Currently, the replay tool will fail on any
files that are not explicitly created by the workload.
