Rewrite SSH-1 RSA handling functions using BinarySource.

Browse Source 
The SSH-1 RSA key reading functions now have BinarySource-shaped get_*
forms, although for the moment I'm still supporting the old API as a
wrapper on the new one, because I haven't switched over the client
code yet. Also, rsa_public_blob_len uses the new system internally,
although its API is unchanged.
