History
Jeffrey Altman cbf126bede Permit NULL context to krb5_get_error_message() 
Application developers have a tendency to use krb5_get_error_message()
as a drop in replacement for error_message() and under various
circumstances they pass in a NULL context.  This method works fine
for MIT's implementation which ignores the context but in Heimdal
passing in a NULL context would dump core.

This patch set modifies krb5_get_error_message() in order to
permit the passing of a NULL context.  First, if the context
is NULL, an attempt will be made to allocate one locally for
the purpose of evaluating the error code.  Second, if a local
context cannot be allocated, fall back on calling error_message().
If error_message() fails to return a string, then generate an
"unknown error" response.

Only if all of the above fails is NULL returned.
