Start RSA_PSS_PARAMS_new(3) stub from scratch. Both functions

are listed in <openssl/rsa.h> and OpenSSL doc/man3/X509_dup.pod.
Note that the OpenSSL documentation specifies the wrong header file.
More could probably be said about PSS, but this is a start...

+.Ft RSA_PSS_PARAMS *
+.Fn RSA_PSS_PARAMS_new void
+.Ft void
+.Fn RSA_PSS_PARAMS_free "RSA_PSS_PARAMS *params"
+.Sh DESCRIPTION
+.Fn RSA_PSS_PARAMS_new
+allocates and initializes an empty
+.Vt RSA_PSS_PARAMS
+object, representing an ASN.1 RSASSA-PSS-params structure
+defined in RFC 8017 appendix A.2.3.
+It references the hash function and the mask generation function
+and stores the length of the salt and the trailer field number.
+.Fn RSA_PSS_PARAMS_free
+frees
+.Fa params .
+.Sh RETURN VALUES
+.Fn RSA_PSS_PARAMS_new
+returns the new
+.Vt RSA_PSS_PARAMS
+object or
+.Dv NULL
+if an error occurs.
