We never actually store anything in input_data (from the conn_rec), so it

doesn't make much sense to check to see if there is something there.  This
removes the input_data brigade from the conn_rec altogether.  There is no
good reason for a filter to be accessing a bucket brigade from within the
conn_rec.  This shouldn't be here anymore, just like the output_filter
shouldn't be storing the data in the conn_rec.
