libbb: introduce bb_signals and bb_signals_recursive,
which sets same handler for many signals. sig_catch is nuked (bb_signals_recursive is more descriptive name). *: use them as appropriate. function old new delta bb_signals_recursive - 95 +95 bb_signals - 52 +52 run_command 258 273 +15 svlogd_main 1368 1377 +9 runsv_main 1746 1752 +6 runsvdir_main 1643 1646 +3 UNSPEC_print 64 66 +2 time_main 1128 1127 -1 ... resize_main 246 210 -36 sig_catch 63 - -63 set_fatal_sighandler 85 14 -71 ------------------------------------------------------------------------------ (add/remove: 2/1 grow/shrink: 5/24 up/down: 182/-548) Total: -366 bytes
