soname policy

[sergey-239]

Joseph,
I remember that you have no versioning policy in general.
However, in the review response [0] reviewer points that it probably good to have your decision on soname and its versioning. I replied:

As 1) Joseph adds the functionality on as needed basis, 2) there
are obvious bugfixes, 3) camotics builds properly with up-to-date version of cbang
and 4) cbang exports c++ classes, I decided to use `version.subversion` as an so version,
leaving `.revision` for bug fixes in cbang. The leading zero in `libcbang0` is from 
upstream, I suspect that it is somehow related to debian packaging/naming, so I 
leaved this as is. 

So, the idea is to have versioned so name up to subversion number, i.e. libcbang0.so.1.7 presently, to allow bug fixes updates of shared cbang library without the need to rebuild camotics.

Do you have any objections or another vision?

Thank you,
Sergey
