This provides an HDFS back-end, allowing IOR to exercise a Hadoop
Distributed File-System, plus corresponding changes throughout, to
integrate the new module into the build. The commit compiles at LANL, but
hasn't been run yet. We're currently waiting for some configuration on
machines that will eventually provide HDFS. By default, configure ignores
the HDFS module. You have to explicitly add --with-hdfs.
Clean up the header files to only contain those things that
need to be shared between .c files.
Functions that are not shared are now declared static to
make their file scope explicit. Functions that ARE shared
are declared in appropriate headers.
I am not going to claim that I caugh everything, but at
least it is a good start.
