modify parse_size_and_unit() to support percentage

Modify parse_size_and_unit() to support a value followed by a '%'
character. In this case ps is required to be non-NULL to ensure the
caller can detect that case. The returned value will be the integer
value s was pointing to and *ps will point to the '%' character.
