Conversion of doc comments from imperative to
indicative mood. Addition of trailing periods
as well.
Fixes: #4074
Motivation
As explained in Issue #4074:
tokio's doc comments are written in a mixture of the indicative mood and imperative mood. They should all be in the indicative mood (e.g. "Returns foo"), to match the stdlib and the standard rustdoc conventions.
Solution
Adapt the doc comments of the main crate to use indicative mood. In addition missing trailing periods were added.
