the librsa* library and reports which version of the library (OpenSSL/RSAREF)
is being used.
This is then used in openssh to detect the failure case of RSAREF and a RSA key
>1024 bits, to print a more helpful error message than 'rsa_public_encrypt() fai
led.'
This is a 4.0-RELEASE candidate.
Reorganize and unify libcrypto's interface so that the RSA implementation
is chosen at runtime via dlopen().
This is a checkpoint and may require more tweaks still.
