Don't export internal symbols

On Linux when creating the .so file we were exporting all symbols. We should
only be exporting public symbols. This commit fixes the issue. It is only
applicable to linux currently although the same technique may work for other
platforms (e.g. Solaris should work the same way).

This also adds symbol version information to our exported symbols.

Fix s_server problem with no-ec

s_server was trying to set the ECDH curve when no-ec was defined. This also
highlighted the fact that the -no_ecdhe option to s_server is broken, and
doesn't make any sense any more (ECDHE is on by default and the only way it
can be disabled is through the cipherstring). Therefore this commit removes
the option.
