Adds support for the PSS padding scheme. Until now, the sign/verify
functions used the old EVP_Sign*/EVP_Verify* OpenSSL API, making it
impossible to change the padding scheme. Fixed by first computing the
message digest and then signing/verifying with a custom EVP_PKEY_CTX,
allowing us to specify options such as the padding scheme and the PSS
salt length.
