556fec24b1 core-linux: avoid block-for-signal assertion 
This patch removes the assertion about the unexpected call of
'block_for_signal' within core. On Linux, this call is actually
expected because of the handling of SIGCHLD signals by core.

a1df4fee44 base: restructure signal-submit initialization 
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.
