[etherlab-users] Real datatypes

We have done something similar to the existing access functions:

#define EC_READ_SINGLE(DATA)    ((float)(*((float *)((DATA)))))
#define EC_WRITE_SINGLE(DATA, VAL) \
do { \
    *((float*) ((DATA))) = (float) (VAL); \
} while (0)


Note that the byte order may be different. In that case you can use
cpu_to_le32 and friends. For us it worked since we also made the slave that
generated the data.
