pydsp: share dsp buffer objects at inplace operation
DSP support for py/pyext: new objects pyext~,pyx~,pyext.~,pyx.~
new base class for py and pyext classes
preset sys.argv for module loading
support for buffer objects (preliminary)
py: bang in left inlet now really triggers without arguments
fixes for detached operation and single-threaded version
little restructuring
adjust pd and py files for correct argument passing
more optimizations
update for new flext callback naming
use lock count instead of message queuing to avoid py->py messaging deadlock
pyext: fix for inlet count
svn path=/trunk/; revision=2624
