Original commit message from CVS:
added unitconvert which has a registry of Units of Measurement and an api to convert one unit to another.
Any required dparam now needs to specify what unit it represents so that an app can convert it to some other unit for presentation/other purposes.
Also added GST_DPMAN_PROCESS_CHUNK macro for elements which don't process their audio one sample at a time (ie, ladspa).
