Add a reconfigure state on the node that is set when the node was IDLE
or RUNNING when reconfigured.
The node state will be set to the running state as long as the
reconfigure state is active. When the node is running, the reconfigure
state is unset again and the node is allowed to IDLE as usual.
This fixes the case where an IDLE (but not paused node) will be
suspended when a rate change happens but will then not resume
afterwards.
This causes problems with rate changes and nodes that have the suspend
disabled by the session manager. They will be suspened anyway and this
can cause problems for devices that need to keep running to keep the
amplifiers active.

This was disabled in 15b4c58e as under various circumstances Gstreamer
pipelines would mmap the DMABufs, which can be very slow in various cases.
One typical example of that is screen casting using a dedicated graphics card.
Thus we only want to use DMABufs if the peer element advertises support for
`GST_CAPS_FEATURE_MEMORY_DMABUF`, ensuring no mapping will happen if we
set the format accordingly.
This allows pipewiresrc to be used with DMABufs for fully accelerated
pipelines or in combination with a download element such as `gldownload`[1]
without regressing the commit above. The `gldownload` approach mirrors
what webrtc (Chromium/Firefox) does, but without duplicating the
functionality into pipewiresrc.
While on it, also implement dmabuf negotiation according to
https://docs.pipewire.org/page_dma_buf.html with the modifiers
`DRM_FORMAT_MOD_INVALID` and `DRM_FORMAT_MOD_LINEAR` in order to allow
dmabuf negotiation with more modern clients, including Gnome-Shell.
1: for now use something like `glupload ! glcolorconvert ! gldownload` -
`gldownload` does not support importing DMABufs yet but `glupload` does.
Dictionaries are by default printed in their insertion order.
This is unergonimic when comparing properties created by different
clients, as they may insert them in different orders.
When we clear the buffers on an output port when we clear the port
format in suspend, also clear the buffers shared by the peer input
port mixers because else they would reference old stale buffers.
Fixes#2914
Incompatible changes between ROC v0.1.X and v0.2.X require
adjusting the ROC modules' code. The largest change is going
from `roc_address` to `roc_endpoint`. There is also a breaking
change, the removal of `local.ip` parameter from module-roc-sink
as `roc_sender_bind()` has been removed.
The API usage was modelled after https://github.com/roc-streaming/roc-pulse

Add a `fd` property to `GstPipeWireDeviceProvider` so it can be used
with fds obtained from e.g. the camera xdg-desktop-portal.
This is needed so apps like Cheese or Camera can easily implement the
camera portal.
Quoting the commit introducing `GstPipeWireCore`:
```
Make all sources in the same process with the same fd share the
connection to the server. This makes it possible to set the same
fd on multiple sources/sinks and have them all use the same
connection, like when capturing multiple monitors from screencast
with the portal.
```
Do the same for `GstPipeWireDeviceProvider`, so it can share a
connection with device sinks as well. This will be needed for fd based
connections introduced in the next commit.
Further more it allows some cleanups.
