Enable larger UDP (safesock) fragmentation sizes. #4321

Add knobs UDP_LOOPBACK_FRAGMENT_SIZE used when going to the loopback
interface (default to largest message size, currently 60k), and
UDP_NETWORK_FRAGMENT_SIZE when going to any non-loopback address
(default to 1000 bytes as before). Note these are not in the param
table because the defaults are based upon constants in CEDAR not
available in the param table code.

(#4320) set CUDA_VISIBLE_DEVICES, etc in environment of jobs on machines that have GPUs
even when the job itself has no GPUs allocated.  This requirement is generalized into
a new knob: ENVIRONMENT_VALUE_FOR_UnAssigned<tag> which defines the value that will
be set into the environment when the slot has <tag> defined but Assigned<tag> is not.
