It can be used to represent C error codes and some error codes of our own devising for use in the runtime.

With the advent of error handling and the Error subclasses currently defined in SysError, we expect the preferred way to interact with error conditions to be either those subclasses (for Chapel code) or symbols defined in OS and OS.POSIX (for C interoperability).

Some version of this symbol will probably be useful for internal purposes, but we're currently leaning towards deprecating the version that lives in SysBasic and not exposing its replacement to users.
