9e36f0475f SHA2 renamed to SHA256, SHA4 renamed to SHA512 and functions accordingly 
The SHA4 name was not clear with regards to the new SHA-3 standard. So
SHA2 and SHA4 have been renamed to better represent what they are:
SHA256 and SHA512 modules.

48f7a5d724 DHE-PSK based ciphersuite support added and cleaner key exchange based 
code selection

The base RFC 4279 DHE-PSK ciphersuites are now supported and added.

The SSL code cuts out code not relevant for defined key exchange methods

8f4ddaeea9 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.

c70b982056 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.

Apps and tests modified accordingly

41c83d3f67 Added Ephemeral Elliptic Curve Diffie Hellman ciphersuites to SSL/TLS 
Made all modifications to include Ephemeral Elliptic Curve Diffie
Hellman ciphersuites into the existing SSL/TLS modules. All basic
handling of the ECDHE-ciphersuites (TLS_ECDHE_RSA_WITH_NULL_SHA,
TLS_ECDHE_RSA_WITH_RC4_128_SHA, TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA,
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA)

1961b709d8 Added ssl_handshake_step() to allow single stepping the handshake 
process

non-blocking network stacks and for getting information from specific
handshake messages if wanted.
