Allow VarStreamArray to use stateful extractors.

Previously extractors tried to be stateless with any additional
context information needed in order to parse items being passed
in via the extraction method.  This led to quite cumbersome
implementation challenges and awkwardness of use.  This patch
brings back support for stateful extractors, making the
implementation and usage simpler.
