Carsten Brandt 3520eee05d SO versions for cmake and libtool
this updates the version-sync script to generate proper SO versions
which will be used by cmake and libtool to create version symlinks
on the system when a library is installed as well as setting the SO
version in the binary.

To see what this does, you have to configure tox with a prefix:

    ./configure --prefix=/tmp/tox-with-libtool
    mkdir cbuild && cd cbuild && cmake -DCMAKE_INSTALL_PREFIX=/tmp/tox-with-cmake ..

Then run `make && make install`.

in both instances you should see the following installed in `lib/`:

    libtoxcore.so -> libtoxcore.so.1.4.0
    libtoxcore.so.1 -> libtoxcore.so.1.4.0
    libtoxcore.so.1.4.0

inside the binary the soname should be the one with .1 and it should not
contain the full version:

    $ objdump -p libtoxcore.so.1.4.0 | grep SONAME
      SONAME               libtoxcore.so.1
