PKCS #8 code for RSA and ECDSA.

Compiles, not yet tested.  Existing tests need conversion to PKCS #8
before we can do anything useful with this.

Once everything uses PKCS #8 instead of algorithm-specific formats, we
can revisit API issues like whether hal_rpc_pkey_load() should still
be taking `type` and `curve` arguments.
