294d1e36c2 RT3066: rewrite RSA padding checks to be slightly more constant time.
Also tweak s3_cbc.c to use new constant-time methods.
Also fix memory leaks from internal errors in RSA_padding_check_PKCS1_OAEP_mgf1

This patch is based on the original RT submission by Adam Langley <agl@chromium.org>,
as well as code from BoringSSL and OpenSSL.

2afb29b480 RT992: RSA_check_key should have a callback arg
The original RT request included a patch.  By the time
we got around to doing it, however, the callback scheme
had changed. So I wrote a new function RSA_check_key_ex()
that uses the BN_GENCB callback.  But thanks very much
to Vinet Sharma <vineet.sharma@gmail.com> for the
initial implementation.

0574cadf85 CMS RSA-OAEP and RSA-PSS support.
Extend RSA ASN1 method to support CMS PSS signatures for both sign
and verify.

For signing the EVP_PKEY_CTX parameters are read and the appropriate
CMS structures set up.

For verification the CMS structures are analysed and the corresponding
parameters in the EVP_PKEY_CTX set.

Also add RSA-OAEP support.

For encrypt the EVP_PKEY_CTX parameters are used.

For decrypt the CMS structure is uses to set the appropriate EVP_PKEY_CTX
parameters.
