ENGINE_cleanup is not being called, as per the curl #ifdef, but
forcing it to be called doesn't actually fully solve the problem (nor
am I sure that it should).  So there does seem to be some mem that
isn't freed by ENGINE_cleanup. 

Now I'm down to:
==15003== 616 bytes in 7 blocks are still reachable in loss record 1 of 1
==15003==    at 0x401B422: malloc (vg_replace_malloc.c:149)
==15003==    by 0x434D0BD: ??? (mem.c:79)

==15003==    by 0x43BA81D: ERR_clear_error (err.c:707)
==15003==    by 0x43A8DAF: ENGINE_load_dynamic (eng_dyn.c:298)
==15003==    by 0x43A71F6: ENGINE_load_builtin_engines (eng_all.c:71)
==15003==    by 0x40829A6: Curl_ossl_init (ssluse.c:548)
==15003==    by 0x4092A5F: Curl_ssl_init (sslgen.c:167)
==15003==    by 0x408BD11: curl_global_init (easy.c:204)
==15003==    by 0x804C2D6: usno_query (usnoquery.c:359)
==15003==    by 0x804941D: main (usnoquery_main.c:81)

So the failure to call ENGINE_cleanup maybe is curls fault.

But ENGINE_load_dynamic calling ERR_clear_error is leaking, possibly
not adding things things to the "needs to be freed" list?
