Make code conforming to rustfmt's expectations

An automated code formatter can help tremendously in reducing the amount
of cognitive energy wasted on thinking about the "best" formatting of
code as well as the number of nitpicks reviews typically get -- the
format is machine checked (and enforced) and there is usually little to
no discussion about the validity.
To reach the goal of having such automated enforcement, we want to run
the rustfmt tool as part of the CI pipeline. With rustfmt having reached
1.0 recently, the believe is that by now the formatting is reasonably
stable and usable for this purpose.
In that light, this change formats the code using rustfmt and prepares
for such an automated style check.
