pull up r18858 from trunk

 ticket: new
 subject: free error message when freeing context
 Target_Version: 1.6
 Tags: pullup

 Call krb5_clear_error_message() to free any allocated error message
 before freeing the context.

 The condition that triggered this was a plugin library which fails to
 load because of unresolved references.  It appears dlopen() on Linux
 leaks four bytes for each failing library in this situation.
