[drmaa-wg] Additional error for C binding

[Rajic, Hrabri]

There is how the spec treats a similar parameter job_name:
 
   DRMAA_JOBNAME_BUFFER = 1024.

At the other place spec says:

job name
A job name SHALL comprise alphanumeric and _ characters.
The drmaa-implementation SHALL NOT provide the client with a job
name longer than DRMAA_JOBNAME_BUFFER -1 (1023) characters.
The drmaa-implementation MAY truncate any client-provided job name
to an implementation-defined length that is at least 31 characters.
The attribute name is drmaa_job_name

I think that the intent was to let the implementation provide adequate
space to job_id since it was not marked as an In parameter.  The app
would copy it in an adequate length buffer (incurring performance hit).
C-spec has done optimization here, but the adequate error code is now
missing in the language independent spec.
