Given a mechanism-specific minor status code like
GSSAPI.Error.minor_status , returns an array containing messages
for all the status values in it. The returned string(s) presumably
don't end with linefeeds.
This wraps GSS_Display_status according to RFC 2743 section
2.4.1.
Parameter minor_status
The mechanism-specific minor status.
Parameter mech
The mechanism that produced the status code. If this is zero or
left out, a system default mechanism is used.
