Add packet service to request kernel debug information (memory dump, kernel objects etc.)

In case of firmware maloperation extensive knowledge about the kernel state significantly increase the chances of identifying the cause of an actual problem. As information about the kernel state is currently only provided via JTAG connection, devices in productive environment are most likely not offering
access to those valuable data.
By introducing a packet service which provides selected kernel information via the build-in mailbox system of the rcX middleware, devices which are difficult to access or even encapsulated devices could be queried for kernel state information.
