Eliminate x86_64 build warnings

Browse Source 
Eliminated all build warnings coming from `make check` with
CFLAGS="-Wall -Wextra" (and some "-pedantic") for an x86_64 target (GCC
9 Ubuntu 16.04, GCC 10 Ubuntu 20.04).  Except for the "Implement
get_list_addr(), please." beg.

This was mostly tagging various parameters as "maybe unused", but there
were a few other changes like assigning to the correct member of
sa_handler and casting things to the right type.

This will hopefully reduce the noise in builds.
