8f1bb31255 lv2: shorter element names
Cut off the protocol part from the uri. Also just g_Strdup, instead of printf
the name.

faa007d4b0 lv2: create valid gobject property names. Fixes #602528
We cannot use the names as we get them from lv2 for the gparamspec name, only
for nick/blurb. Apply same algorithms like elsewhere (ladspa) for name.

1803eb4d7a lv2: set the audio-channel positions again, but now in _setup
Readd the code that was reverted for the release. We now set audio-channel
positions if any on the pad caps and not on the templates.

d7a4293774 lv2: only use g_return_val_if_fail for checking pre-conditions
g_return_* can be disabled. Still we want to check for failed instance creation.

8a5e9a3363 signalprocessor: change _setup to pass whole caps and not just sampling_rate
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.

fac1f741c3 signalprocessor: Use correct CFLAGS for the signalprocessor headers in LV2/LADSPA
This makes sure that the headers from the source tree are taken and not
accidentially installed system headers in the case of builddir!=srcdir.

Fixes bug #602161.

38592a566d signalprocessor: don't set channel positions in template-caps, Fixes #601775
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.

fa47a5ff3a More tolerate port group support, plugin cleanup.
Gracefully handle plugins with illegal groups that contain no symbol by
treating ports in that group normally (i.e. as if they weren't part of a
group).  The port groups spec mandates that groups have a valid unique
symbol, but plugins aren't perfect...

Make (conceptually) static plugin variables actually (C) static,
and clean up SLV2 related things with a GCC shared library destructor,
if GCC is in use.

374d52d257 Multi-channel support with channel positions.
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.

b849ae89b5 Separate port discovery from pad template creation.
This first counts ports (using the builtin slv2 functions to do so
rather than manually as before), then creates descriptors for each port
and finds all port groups.  Only then are pad templates created (towards
using group information for creating multi-channel pads).

5a8e9cd080 signalprocessor: Fix various build/dist issues
Install the headers, version the library with @GST_MAJORMINOR@,
add all required libraries to _LIBADD instead of _LDFLAGS,
and add GST_*_LDFLAGS to _LDFLAGS.

ea184d72f5 Working LV2 plugin discovery.
- Separate gstsignalprocessor into a separate library (not sure if this
  is in the right place, but it works for now anyway)
- Create LV2 element based on LADSPA element, port most discovery
  functionality
