Ability to specify allowed ciphersuites based on the protocol version.

The ciphersuites parameter in the ssl_session structure changed from
'int *' to 'int *[4]'.
The new function ssl_set_ciphersuite_for_version() sets specific entries
inside this array. ssl_set_ciphersuite() sets all entries to the same
value.

OID functionality moved to a separate module.
...
A new OID module has been created that contains the main OID searching
functionality based on type-dependent arrays. A base type is used to
contain the basic values (oid_descriptor_t) and that type is extended to
contain type specific information (like a pk_alg_t).
As a result the rsa sign and verify function prototypes have changed. They
now expect a md_type_t identifier instead of the removed RSA_SIG_XXX
defines.
All OID definitions have been moved to oid.h
All OID matching code is in the OID module.
The RSA PKCS#1 functions cleaned up as a result and adapted to use the
MD layer.
The SSL layer cleanup up as a result and adapted to use the MD layer.
The X509 parser cleaned up and matches OIDs in certificates with new
module and adapted to use the MD layer.
The X509 writer cleaned up and adapted to use the MD layer.

The SSL session cache module (ssl_cache) now also retains peer_cert information (not the entire chain)
...
The real peer certificate is copied into a x509_buf in the
ssl_cache_entry and reinstated upon cache retrieval. The information
about the rest of the certificate chain is lost in the process.
As the handshake (and certificate verification) has already been
performed, no issue is foreseen.
