> Libhdfs doesn't have this but libhdfs3 has a "hdfsGetLastErrorString" 
> function.  The C API needs to be able to pass out error messages that are 
> more specific than what errno can provide.
> This functionality should be exposed via a new public header in order to keep 
> hdfs.h consistent with the libhdfs header.
