 subject: Add DEBUG_ERROR_LOCATIONS support

 If DEBUG_ERROR_LOCATIONS is defined, replace uses of
 krb5_set_error_message and krb5int_set_error with calls to the new
 _fl variants of those functions, and include filename and line number
 information in the calls.  Requires C99-style variadic macros if
 defined.
