## Changes
This was an issue in cases where the typed structure contains a non-nil
pointer to an empty struct. After conversion to a `dyn.Value` and back
to the typed structure, the pointer became nil.
## Tests
Unit tests.
## Changes
In the dynamic configuration, the nil value (dyn.NilValue) denotes a
value that should not be serialized, ie a value being nil is the same as
it not existing in the first place.
This is not true for zero values in maps and slices. This PR fixes the
conversion from typed values to dyn.Value, to treat zero values in maps
and slices as zero and not nil.
## Tests
Unit tests
## Changes
The name "dynamic value", or "dyn" for short, is more descriptive than
the opaque "config". Also, it conveniently does not alias with other
packages in the repository, or (popular ones) elsewhere.
