Add native support for serializing char arrays without FLATDATA

Browse source 
Support is added to serialize arrays of type char or unsigned char directly,
without any wrappers. All invocations of the FLATDATA wrappers that are
obsoleted by this are removed.

This includes a patch by Russell Yanofsky to make char casting type safe.

The serialization of CSubNet is changed to serialize a bool directly rather
than though FLATDATA. This makes the serialization independent of the size
of the bool type (and will use 1 byte everywhere).
