4745d652b5 pki_crypto.c: plug ecdsa_sig->[r,s] bignum leaks
Per ecdsa(3ssl), ECDSA_SIG_new does allocate its 'r' and 's' bignum fields.
Fix a bug where the initial 'r' and 's' bignums were being overwritten with
newly-allocated bignums, resulting in a memory leak.

aaae6cd97d pki_gcrypt: Initialize 'type_c' in 'pki_do_sign_sessionid'
Add missing initialization of 'type_c' field of a SSH signature in
'pki_do_sign_sessionid' procedure.

If libssh is compiled with GCrypt, 'dh_handshake_server' fails with
"Could not sign the session id" error.  The change fixes that.
