5de9d5809b audioconvert: Handle fallback channel mask for mono correctly

8d4f79b640 audiodecoder: fix invalid timestamps when PLC and delay 
Elements inherited from GstAudioDecoder, supporting PLC and introducing
delay produce invalid timestamps. Good example is opusdec with in-band FEC
enabled. After receiving GAP event it delays the audio concealment until
the next buffer arrives. The next buffer will have DISCONT flag set which
will make GstAudioDecoder to reset it's internal state, thus forgetting
the timestamp of GAP event. As a result the concealed audio will have the
timestamp of the next buffer (with DISCONT flag) but not the timestamp
from the event.

f7a31a79f4 audio: Add const to segment parameter of gst_audio_buffer_clip()

802eae296a Revert "audioringbuffer: start ringbuffer if needed upon commit" 
This reverts commit 13ee94ef10.

Causes audio glitches at startup by starting to output segments
from the ringbuffer before it has been filled / fully prerolled.

7c5dfd713c audioringbuffer: don't attempt to reorder position-less channels 
As said in its doc GST_AUDIO_CHANNEL_POSITION_NONE is meant to be used
for "position-less channels, e.g. from a sound card that records 1024
channels; mutually exclusive with any other channel position".

But at the moment using such positions would raise a
'g_return_if_reached' warning as gst_audio_get_channel_reorder_map()
would reject it.

Fix this by preventing any attempt to reorder in such case as that's not
what we want anyway.

3cb08304da gst-audio: add gst_audio_channel_positions_to_string() 
We currently don't log much about channel positions making debugging
harder as it should be. This is the first step in my attempt to improve
this.

bfcd0737b7 audio: Fix a race with the audioringbuffer thread 
There is a small window of time where the audio ringbuffer thread
can access the parent thread variable, before it's initialized
by the parent thread. The patch replaces this variable use by
g_thread_self().

37c4915109 libs: audio: split allocation query caps and pad caps 
Since the allocation query caps contains memory size and the pad's caps
contains the display size, an audio encoder or decoder might need to allocate
a different buffer size than the size negotiated in the caps.

This patch splits this logic distinction for audiodecoder and audioencoder.

Thus the user, if needs a different allocation caps, should set it through
gst_audio_{encoder,decoder}_set_allocation_cap() before calling the negotiate()
vmethod. Otherwise the allocation_caps will be the same as the caps in the
src pad.
