Alberto Bertogli f3b01cb493 docs: Add missing docstrings, adjust wording to match standard style
This patch adds a missing docstrings for exported identifiers, and
adjust some of the existing ones to match the standard style.

In some cases, the identifiers were un-exported after noticing they had
no external users.

Besides improving documentation, it also reduces the linter noise
significantly.
