json: fail read_string if string contains trailing garbage
Change `read_string` to fail when not the entire input has been
consumed. This avoids unexpected, even dangerous behavior (fixes #6223).
The new JSON parser adapted in #6121 also solves this problem so in
master this is a temporary fix, but should be backported to older releases.
Also adds tests for the new behavior.
