Fix a Y2038 problem, by conversion of long to time_t.

The TS_RESP_CTX_set_time_cb() API gets removed. Nothing in the greater
ecosystem ever calls it.  This API needs to be removed, because if
anyone ever calls on a BE 32 system assuming long rather than time_t,
it will be dangerously incompatible.
