f37b9ad67b impl-node: fix reposition handling 
We only need to sync clients when start/stop has been issued otherwise
we simply write the new position values in the driver segment.

Don't overwrite bar/video position info with invalid values.

41989f4889 client-node: don't overwrite the chunk memory pointer 
When the client uploads a buffer, copy all data fields except for
the chunk memory that we configured before.
If we overwrite the chunk memory, the users of the buffer would not
be able to find the chunk memory anymore and crash or fail.

8ecef35e80 client-node: update n_buffers after we can process them 
Make sure we don't configure the buffers before we manage to
completely process them or else we are left with an invalid list
of buffers.

7ead270265 Implement JSON/YAML command for graph tree traversal 
Implement a single command that allows viewing all information
about a remotes properties/parameters and info variables.

This patch creates a framework for accessing properties using
a simple dotted variable access method or JSON/YAML path expressions.

The root of the tree is a sequence of all globals objects, and
accessing a the first one is simply 0 (or /0 is JSON/YAML path form).

	   display Spa:Enum:ParamId:EnumFormat

3b53a6e049 pw-cli: Collect and display parameters from global symbols 
Until now there was no method to display parameters along with
information of their parent object.

This patchset stores parameter info in the global object so
that it may displayed along with its parent object.

This is a necessary step to be able to display and modify parameters
in a simple form like the following

pipewire-0>> set 12 volume=0.7
pipewire-0>> get 12 volume
0.7
