usctest.h, parse_opts.c: Hide unused variables.

Hide all unused variables from usctest.h and declare them static in
parse_opts.c.

Full list is:

STD_PAUSE
STD_INFINITE
STD_argind
STD_LOOP_DURATION
STD_LOOP_DELAY

Also removes unused STD_nopts from parse_opts.c completly and decleare
std_option_t as static.
