Merge of r4919: fixed segfault on PUT in dav module.
Dav: fixed segfault on PUT if body was already read (ticket #238).
If request body reading happens with different options it's possible
that there will be no r->request_body->temp_file available (or even
no r->request_body available if body was discarded). Return internal
server error in this case instead of committing suicide by dereferencing
a null pointer.
