There's no support in the CSV driver for binary data

> 2. Can a field in a CSV input files have a IntegerList or a Binary?

No. Well on writing, the IntegerList will be serialized as a string. But not 
recognized as IntegerList on reading

The default serializatoin will be (number_of_elements:val1,val2,...,valn), but 
currently it is truncated to 80 chracters

> 4. "Boolean, Int16, Float32" are mentioned as subtypes. Are there more
> subtypes?

Not currently. See https://trac.osgeo.org/gdal/wiki/rfc50_ogr_field_subtype
