a small patch

[Xi Wang]

Hi,

Attached is a patch that addresses the following problems.

* two memory leaks: enc_session (kex.c:781), session->packet_callbacks
(session.c:209);

* openssl configuration problem: use OPENSSL_FOUND instead of
CRYPTO_FOUND, which doesn't exist in my cmake 2.8.

* compile warnings: avoid using the name "signal" (channels.c);

* link error when WITH_SERVER=0 (packet.c:59);

* minor compile error (torture_options.c).

Hope it helps.

Thanks,
- xi
