This patch allows core's 'Signal_transmitter' implementation to sidestep the 'Env::Pd' interface and thereby adhere to a stricter layering within core. The 'Signal_transmitter' now uses - on kernels that depend on it - a dedicated (and fairly freestanding) RPC proxy mechanism for signal deliver, instead of channeling signals through the 'Pd_session::submit' RPC function.
