[v7,00/21] dts: docstrings update

  The first commit makes changes to the code. These code changes mainly
change the structure of the code so that the actual API docs generation
works. There are also some code changes which get reflected in the
documentation, such as making functions/methods/attributes private or
public.

The rest of the commits deal with the actual docstring documentation
(from which the API docs are generated). The format of the docstrings
is the Google format [0] with PEP257 [1] and some guidelines captured
in the last commit of this group covering what the Google format
doesn't.
The docstring updates are split into many commits to make review
possible. When accepted, they may be squashed.
The docstrings have been composed in anticipation of [2], adhering to
maximum line length of 100. We don't have a tool for automatic docstring
formatting, hence the usage of 100 right away to save time.

NOTE: The logger.py module is not fully documented, as it's being
refactored and the refactor will be submitted in the near future.
Documenting it now seems unnecessary.

v7:
Split the series into docstrings and api docs generation and addressed
comments.
