We discovered that attempting to print a very large string-like array would succeed on the CLI, but in DAP would cause the "variables" request to fail with: value requires 67038491 bytes, which is more than max-value-size This turns out to be a limitation in Value.format_string, which de-lazy-ifies the value. This patch fixes this problem by introducing a new NoOpStringPrinter class, and then using it for string-like values. This printer returns a lazy string, which solves the problem. Note there are some special cases where we do not want to return a lazy string. I've documented these in the code. I considered making gdb.Value.lazy_string handle these cases -- for example it could return 'self' rather than a lazy string in some situations -- but this approach was simpler.
