Description

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.
