Change DSO versioning scheme

Browse Source 
This commit introduces the same shared library versioning scheme as used
by the SDL library.  The advantage is that different versions of
notcurses can be installed alongside each other (which is not an
unlikely scenario, as SDL itself certifies) and that, if the versioning
protocol is followed, any change to ABI will produce a DSO whose name
will not break any applications linked against any previous version.
