curlDebugType not up-to-date, may lead to segfault

[nojb]

It is missing the cases CURLINFO_SSL_DATA_IN and CURLINFO_SSL_DATA_OUT and the conversion in curl-helper.c (function cb_DEBUGFUNCTION) assumes the OCaml constructors correspond exactly with the C enum (see here in current master).

Thanks, there was another potential segfaul in same function %)
