Alex Lin ae07b26243 ICG exclude of class member variables now defines incorrect memory offsets in io_src #311
Added back the code that set the offset of variables with the offsetof function. This
code is running by default.  Any code that includes #ifndef TRICK_ICG in
classes/structures will want this on.

Added a flag to ICG that allows us to turn off writing of these lines.  If the flag
is present, ICG may write out io_src code for private/protected variables that it could
not reach if an offsetof function was required.  Code cannot have any #ifndef TRICK_ICG
present in classes/structures for this to work.
