Unifying the naming of functions between BASOP and float

Already mentioned in issue #1035 (closed) and also discussed in MR !793 (closed) and this is catch the exact task.

It is evident that there is a mismatch between function naming when comparing the float reference and the BASOP conversion. Although this does not affect the functionality, it makes the review of changes sometimes a bit hard and also affects debugging. Moreover, the added WMOPS_DETAIL functionality from MR !793 (closed) is much more useful if there is a clear one-to-one mapping between automatically created WMOPS measures of BASOP and float reference.

As this task will probably conflict with a lot of work in the decoder and renderer libraries, it is best to do it in a one go, review, and merge in.
