965b220206 module-rtp: clear ringbuffer in resync 
When we resync to the timestamp, clear the ringbuffer to avoid playing
old stale samples.

aed394cf89 module-rtp: use timestamps as ringbuffer index 
Use the timestamps directly as the ringbuffer index. We can save some
conversions to bytes and there is a direct mapping to RTP timestamp,
clock position and ringbuffer index.

Simplify the source a little. Remove the buffering state, we always
start with read and write pointers separted by the target buffering.

1a5de467db module-rtp: support direct clock timestamps 
Always use the timestamp of the graph clock for RTP packets. Add an
option to apply a random or fixed offset.
Add a ts-refclk option on the sender to specify a reference clock to
use for timestamping. This will activate the direct timestamp mode and
signal this in the SDP.

Parse ts-refclk and ts-offset from the SDP. Make it possible to match
them in rules. Add option to activate the direct-timestamp, where the
rate matching is disabled and the timestamps are used directly for
writing and reading from the ringbuffer using the graph clock.

This makes it possible to set a PTP clock on sink and source and avoid
rate matching by using a shared clock.

fab9d12a44 module-rtp-source: use simple boolean to check activity 
Avoid doing clock_gettime for each RTP packet and use a simple boolean
to check if packets arrived since the last SAP timeout check.

9fb44c3a71 module-rtp-source: improve buffer handling 
Try to keep half the packet size in the ringbuffer as well. This helps
us adapt to the packet size of the sender.

Drop samples from the ringbuffer for the first packet we read. This
makes us lock onto the stream with the exact requested latency.

f2c3baf93f module-rtp-source: make SAP cleanup interval configurable 
Audinate AES67 devices send SAP messages with 30-second interval, so hardcoded timeout has to be bumped. Just bumping it will reduce efficiency of common RTP module use-case, so a config is introduced for this. 70 second will be set as default for AES67 mode.

860b8fc27f modules: fix rate update 
Setting the rate with the PROP_rate would actually result in a rate
adjustment of 1.0f / rate, so do the same here.

2f397035b8 modules: don't call pw_stream_set_control in process 
pw_stream_set_control can only be used from the pipewire main_loop, not
the process callback. Instead, use the rate_match field directly.

Fixes #2633
