  A+C: Add information about my contributions

splitX bugfix test + simplification

In the process of going through b code I've noticed that splitX bug fix (commit 5c732b36) handling logic was not covered by tests for edge cases and that this edge-handling logic itself can be simplified. Please find patches which add corresponding test and do the simplification attached.

The simplified logic will be handy for upcoming work.

Please see details in individual commit messages.

Thanks beforehand,
Kirill

As requested by @cznic add information about me and my company to
AUTHORS and CONTRIBUTORS.

Btw, I'm not a lawyer and maybe there are country differences, but I
used to think that:

- author is the person who actually creates the work.
- copyright holder is who owns the copyright on that work (i.e. the
  person, or company he is working for or someone else).

The `AUTHORS` file however gets it the other way - it says to put there
information about who is "copyright holder" which goes counterwise above
classification.

I understand however that the exact A+C approach is taken from the Go
project so let's also continue following it here.
