Subject: [PATCH] Avoid RSA type redefinition

The host_key.h headers does:

  typedef struct rsa_st RSA;

But this type definition is already done by the OpenSSL headers.

While such a type redefinition is legal with recent gcc versions, it
doesn't build with older gcc versions such as gcc 4.4.

To work around this problem, we instead use a forward declaration of
"struct rsa_st", and change the only place where the RSA type was used
by "struct rsa_st".
