Rework the system to generate shared libraries:

  - Make note of the expected extension for the shared libraries and
    if there is a need for symbolic links from for example libcrypto.so.0
    to libcrypto.so.0.9.7.  There is extended info in Configure for
    that.

  - Make as few rebuilds of the shared libraries as possible.

  - Still avoid linking the OpenSSL programs with the shared libraries.

  - When installing, install the shared libraries separately from the
    static ones.
