- lib/cwtest.c (enter_test_mode_231, prepare_test_mode_231,
start_test_mode_231, cw_test_begin): broke enter_test_mode_231 into
a slow setup component and a fast start/resume component
- include/cwtest.h (cw_test_resume), lib/cwtest.c (cw_test_resume):
resume transmission in a previously set up test mode
- lib/Makefile (OBJS), include/cwtest.h (cw_test_begin, cw_test_end),
lib/cwtest.c (enter_test_mode_230, enter_test_mode_231,
cw_test_begin, cw_test_end): moved constant wave test mode setup
over from atrf-txrx.c
- atrf-txrx/atrf-txrx.c (transmit_pattern): use functions from cwtest.o
