Not implementing a size estimator had the effect that strings retrieved from
the attributes were treated as "unknown size", leading to wildly overestimating
the cost and validation errors even for even simple expressions like this:

    device.attributes["qat.intel.com"].services.matches("[^a]?sym")

Maximum number of elements in maps and the maximum length of the driver name
string were also ignored resp. missing. Pre-defined types like
apiservercel.StringType must be avoided because they are defined as having
a zero maximum size.
