This allows to get rid of the sampling_rate variable in the base-class. Also now
subclasses can modify the caps to actualy negotiate. This is needed to e.g. set
audio-channel positions.
Revert the changes that added audio positions to template caps. We have an un-
fortunate limitation in core that does not allow to do it. Keep a few things
commented out, so that the channel position can later on be set in setcaps.
This queries port roles from the LV2 data and converts it into GStreamer
channel positions. This should allow any type of multi-channel plugin
(including beyond stereo, e.g. surround) to work fine in GStreamer,
and with elements that require channel positions to be explicitly stated.
Use glib defines for searchpath separators. Filter searchpath to avoid scanning
path entries twice. Fix the return in ladspa_plugin_directory_search to return
wheter we found a plugin.

Whitespace.

Add a FIXME:. not sure if this code does the forwarding correctly.

* ext/ladspa/gstladspa.c: (gst_ladspa_base_init),
(gst_ladspa_class_init), (ladspa_describe_plugin), (plugin_init):
Don't use GST_BOILERPLATE as the stuff generated from it is not used
anyway and can't be used.
Store the class struct of the correct type in parent_class.
Pass the LADSPA_Descriptor as class_data to the class_init function
as preparation for the time, when we can add pad templates and friends
in class_init and add a FIXME for that.
Don't use a custom hash table for passing the LADSPA_Descriptors to
base_init but use g_type_set_qdata and g_type_get_qdata.

abort() in any case but properly report the error.

* ext/ladspa/gstsignalprocessor.h: Add infrastructure for storing
whether a processor can work in place or not, and for keeping
track of its state. Change the FlowReturn instance variable from
"state" to "flow_state", all callers changed.
* ext/ladspa/gstsignalprocessor.c (gst_signal_processor_setup)
(gst_signal_processor_start, gst_signal_processor_stop)
(gst_signal_processor_cleanup): New functions to manage the
processor's state.
(gst_signal_processor_setcaps): start() as well as setup() here.
(gst_signal_processor_prepare): Respect CAN_PROCESS_IN_PLACE.
(gst_signal_processor_change_state): Stop and cleanup the
processor as we go to NULL.
* ext/ladspa/gstladspa.c (gst_ladspa_base_init): Reuse buffers if
INPLACE_BROKEN is not set.
* ext/ladspa/gstsignalprocessor.c (gst_signal_processor_prepare):
Do the alloc_buffer in bytes, not frames.

* Updates for two-arg init from GST_BOILERPLATE.
* ext/ladspa/gstsignalprocessor.c (gst_signal_processor_init): Use
the second arg for the class, because G_OBJECT_GET_CLASS (self)
returns the wrong thing.
(gst_signal_processor_add_pad_from_template): Make pads of the
right type.
* ext/ladspa/gstladspa.c (gst_ladspa_class_get_param_spec): Make
writable param specs G_PARAM_CONSTRUCT so default values work.
(gst_ladspa_init): Use the second arg for the class.

second batch :
remove ',' at end of enums as they could confuse older gcc, foreign compilers (forte) and gtk-doc
(in gst-plugins/ext/ this time)
Original commit message from CVS:
Fix this too. Note that the per-plugin licensing is gone because of company's new per-plugin (rather than per-element) API. We basically need both... Ohwell, I just want this stuff to compile.
Original commit message from CVS:
New typefind system:
* bytestream is now part of the core
* all plugins have been modified to use this new typefind system
* asf typefinding added
* mpeg video stream typefiding removed because it's broken
* duplicate typefind entries removed
* extra id3 typefinding added, because we've seen 4 types of files
(riff/wav, flac, vorbis, mp3) with id3 headers and each of these needs
to work. Instead, I've added an id3 element and let it redo typefiding
after the id3 header. this needs a hack because spider only typefinds
once. We can remove this hack once spider supports multiple typefinds.
* with all this, mp3 typefinding is semi-rewritten
* id3 typefinding in flac/vorbis is removed, it's no longer needed
* fixed spider and gst-typefind to use this, too.
* Other general cleanups
