Original commit message from CVS:

* ext/ladspa/gstsignalprocessor.c:
(gst_signal_processor_add_pad_from_template)
(gst_signal_processor_fixate): Add a fixate function, to assist in
pathological ladspa-sine-fcac ! fakesink can-activate-pull=true
cases.
(gst_signal_processor_prepare, gst_signal_processor_process): Add
nframes args so that getrange can tell ladspa how many frames to
process.
(gst_signal_processor_ouija_caps): setcaps needs to be called
before processing, which normally happens when chaining a buffer
to a pad. However in getrange mode with no sinks we need to check
explicitly for this condition, guess some caps to use, and use
those to setcaps(). Hence this mystical function.
(gst_signal_processor_do_pulls): Pull in bytes, not samples.
Divine the caps if necessary.
(gst_signal_processor_getrange): Interpret the length as bytes,
not samples.
(gst_signal_processor_chain): nframes=G_MAXUINT, will be limited
by incoming buffer sizes.
