---------------------------+------------------------------------------------
 I find function make_ctr_evp in file openssl.c is not is not thread safe,
 only one EVP_CIPHER is used for some threads concurrently.

 Function _libssh2_transport_read in file transport.c use function decrypt
 two times. for first time, p->payload should be NULL, then
 LIBSSH2_FREE(session, p->payload) will caught exception.
