ae9911617e Revert "alsasrc: lock calls to snd_pcm_delay() with mutex as in alsasink"
This reverts commit 4f88125b3d.

This seems to have undesirable side-effects and needs more
investigation first.

4f88125b3d alsasrc: lock calls to snd_pcm_delay() with mutex as in alsasink
Alsasrc introduced delay_lock in commit 519f85a43e73efb8f3fb2c7be45226e
because alsa-lib is not thread safe for the same handle.
Alsasrc uses the same threading pattern, it should be locked too.

a2f8ec4f5a ringbuffer: add support for timestamps
Make it possible for subclasses to provide the timestamp (as an absolute time
against the pipeline clock) of the last read data.
Fix up alsa to provide the timestamp received from alsa. Because the alsa
timestamps are in monotonic time, we can only do this when the monotonic clock
has been selected as the pipeline clock.

dae848818d audio: rework audio caps.
Rework the audio caps similar to the video caps. Remove
width/depth/endianness/signed fields and replace with a simple string
format and media type audio/x-raw.
Create a GstAudioInfo and some helper methods to parse caps.
Remove duplicate code from the ringbuffer and replace with audio info.
Use AudioInfo in the base audio filter class.
Port elements to new API.
