fix to adder: don't pull on unusable pads

Original commit message from CVS:
* fix to adder: don't pull on unusable pads
* fix to ladspa: get output buffers first, so we can know how many frames to
process
- this breaks inplace buffer stuff, hmm
* fix to float2int: add a bufferpool with the same nframes as the source pad's
pool -> no extra latency
