Original commit message from CVS:
A fairly large reworking of the ladspa _get, _chain and _loop funcs.
highlights are:
- pad names are now g_strcanonised
- in all cases possible, src and sink buffers are shared
- all ladspa properties are exposed as dparams and element properties
- the buffers are now processed in dparam driven loops
- timestamps on buffers should be correct
- misc fixes

It has been minimally tested - the following pipeline works for me:
