binary-xml-wire-format: Partial enabling of binary-xml-wire-format

Due to significant changes, Data abstraction conversion (from and to
wire format) is currently disabled, using empty placeholders instead.

Other data structures should have working conversion (minus
PublisherPublicKeyDigest, which is not part of Interest and
ForwardingEntry data structure anymore).
