openslessink: Silence some error debug output to log output

These are not really errors, just unsupported features we don't
necessarily need.
openslesringbuffer: Provide the size of our array to GetDestinationOutputDeviceIDs

Otherwise it does not and just fails. It needs to know the size of the
array to not write too much to it.
examples: fix compilation of gl fxtest example on win32 with Gtk+ 3.0

before setting to null to make sure no buffers are pending

openjpeg: Win32-compatible OpenJPEG-2.0 detection

OpenJPEG 2.0 API uses stdcall on W32 by default. This prevents normal
autoconf library macros from finding its functions.
A more compatible check is to acutally link a program that includes a
real header.

katedec: handle streamheaders in caps

Properly handle the caps event by configuring the kate decoding lib using the
available streamheaders. This makes it possible to decode kate subtitles when
the stream is seeked before katedec gets the initial buffers that are usually
the streamheaders.

katedec: handle segment event earlier

Delaying the segment event to when caps are decided can cause issues as
the first thing katedec does on its chain function it doing a segment clip.
It will lead to an assertion if the segment format is undefined
