Subject: [PATCH] cmake: Add SOVERSION option

The SOVERSION option allows to version the shared library. Version
defined there is 0 and the versioned library files have extension
`so.0`. Optional soversion is helpful for packaging and making a
difference between `lib*` package (which contains `.so.0` file)
and `*-devel` package (which contains `.so` file).

 where performance is the overriding concern, `OPENSSL_SMALL` can be defined to
