Hash :4545807d Message :Fix UB in evutil_date_rfc1123()
As pointed in https://github.com/libevent/libevent/pull/417#issuecomment-267860738
"code is unsafe because in evutil_date_rfc1123() the pointer to the
automatic variable struct tm cur is used outside the scope it defined."
Checked with `clang -fsanitize=address -fsanitize-address-use-after-scope`
and test that call evutil_date_rfc1123() with tm==NULL
