da15c61608 Add CMS_SignerInfo_get0_signature function. 
Add function to retrieve the signature from a CMS_SignerInfo structure:
applications can then read or modify it.

dc1ce3bc64 Add KDF for DH. 
Add X9.42 DH KDF. Move sharedinfo generation code to CMS library as the
same structure is used by DH and ECDH.

Move ASN1_OBJECT typedef to ossl_typ.h so it can be picked up by dh headers
without the need to use ASN1.

17c2764d2e CMS support for key agreeement recipient info.

algorithm specific code in the relevant public key ASN1 method.

e365352d6a CMS public key parameter support. 
Add support for customisation of CMS handling of signed and enveloped
data from custom public key parameters.

This will provide support for RSA-PSS and RSA-OAEP but could also be
applied to other algorithms.

e1f1d28f34 Add function CMS_RecipientInfo_encrypt 
Add CMS_RecipientInfo_encrypt: this function encrypts an existing content
encryption key to match the key in the RecipientInfo structure: this is
useful if a new recpient is added to and existing enveloped data structure.

Add documentation.

146b52edd1 Fix for CMS/PKCS7 MMA. If RSA decryption fails use a random key and 
continue with symmetric decryption process to avoid leaking timing
information to an attacker.

Thanks to Ivan Nestlerode <inestlerode@us.ibm.com> for discovering
this issue. (CVE-2012-0884)

eb1c48be6f Add new type ossl_ssize_t instead of ssize_t and move definitions to 
e_os2.h, this should fix WIN32 compilation issues and hopefully avoid
conflicts with other headers which may workaround ssize_t in different ways.
