context: Wrap find_ec_key in #ifndef OPENSSL_NO_ECDH

"#ifndef OPENSSL_NO_ECDH" is a ridiculous conditional, by the way.
context: Don't leak EC_KEY in set_curve()

SSL_CTX_set_tmp_ecdh() takes a reference to the provided key.

ssl.lua: Comment subtle DH/ECDH ordering caveat
Add useful context to various error messages
context: for dhparam_cb, pass is_export as boolean

The integer value that's actually returned for this flag is 2, which is fine
for C (it is defined as true), but it's sufficiently surprising (because it's
not 1), that this is worth fixing -- even if export ciphers aren't common.

It should be a boolean anyway.
context: Link SSL_CTX to p_context (not lua_State)

This is needed because the p_context is going to cache DH (and eventually
EC_KEY) objects, to plug a leak in the dhparam callback.
