We should avoid alternatives. They make APIs confusing because users see 
what is the same thing and attempt to figure out differences that do not 
exist.

I am happy to see rtems_status_text move from error.c to the sapi and 
changed to be just the text.

I am fine with this becoming just the text of the errors.

Yeap lets fix this.

Now this has been raised I think all these functions are incorrectly 
named. The rtems_status_text is currently a description and that should 
change to be just the text and the ones you added are text. A 
description is something you have in a user manual or man page.
