Import of SSLeay-0.9.0b with RSA and IDEA stubbed + OpenBSD build
functionality for shared libs. Note that routines such as sslv2_init and friends that use RSA will not work due to lack of RSA in this library. Needs documentation and help from ports for easy upgrade to full functionality where legally possible.
