Point-to-point physical links (e.g., Serial, USB, KCS) do not provide presence interrupts when an endpoint attaches or reboots, requiring manual intervention to trigger endpoint discovery. Add autonomous periodic probing for point-to-point interfaces in Bus Owner mode. When an interface is brought UP, mctpd periodically sends Get Endpoint ID requests until the endpoint responds, assigns an EID, and publishes the endpoint on D-Bus. Probing automatically pauses when the link goes DOWN and resumes if the peer is removed. Also add configuration options in mctpd.conf for auto-discovery, probe intervals, and static EID reservations, along with corresponding unit tests. Signed-off-by: Jasmine Cha <chajasmine@google.com>
