a27dfdc058 internal/pipewire: implement Core::CreateObject
Nothing uses this right now, this would have to be called by wrapper methods on Registry that would search the objects

ffbec828e1 internal/pipewire: move Core wrapper methods under Core
These do not belong under Context, and is an early implementation limitation that carried over.

de0467a65e internal/pipewire: treat noAck violation as fatal
Receiving this event indicates something has gone terribly wrong somehow, and ignoring Core::BoundProps causes inconsistent state anyway.

b5999b8814 internal/pipewire: implement Core::RemoveId
This is emitted by the server when a proxy id is removed for any reason. Currently, the only path for this to be emitted is when a global object is destroyed while some proxy is still bound to it.

47db461546 internal/pipewire: generic Core::Error handling
This flushes message buffer before queueing the event expecting the error. Since this is quite useful and relatively complex, it is relocated to a method of Context.

0e2fb1788f internal/pipewire: implement Registry::Destroy
This requires error handling infrastructure in Core that does not yet exist, so it is not exported for now. It has been manually tested via linkname against PipeWire.

d8417e2927 internal/pipewire: implement Registry::GlobalRemove
This is emitted by PipeWire when a global object disappears, because PipeWire insists that all clients that had called Core::GetRegistry must constantly sync its local registry state with the remote.

b9b9705b52 internal/pipewire: specify opcode and file count with message
This adds checking of FileCount while writing a message. Message encoding is relocated to an exported method to be used externally, probably for test stubbing.
