The recent updates to libssl to enforce stricter return code checking, left
a small number of instances behind where return codes were being swallowed
(typically because the function they were being called from was declared as
void). This commit fixes those instances to handle the return codes more
appropriately.

Change ssl_set_handshake_header from return void to returning int, and

Mark most functions returning a result defined in any libssl header file
with __owur to warn if they are used without checking the return value.
Use -DUNUSED_RETURN compiler flag with gcc to activate these warnings.
Some functions returning a result are skipped if it is common and valid to
use these functions without checking the return value.

Rewrite ssl3_send_client_key_exchange to retain the premaster secret
instead of using it immediately.

This is needed because the premaster secret is used after the client key
exchange message has been sent to compute the extended master secret.
