Summary: potential null pointer dereference

Initial Comment:
Expat version 2.1.0

There may be a potential null pointer dereference in the xmlparse.c file, line 2914. The lookup function
may return NULL and this case is not checked before the line #2914. I'm not familiar with expat details,
however in general if such case is not possible, it would be good to make sure the program will be
terminated/aborted, for instance using assert:
assert(id);
