- fix "noreduce" flag of config_read (didn't work at all, at least for me).

- convert init's inittab parsing to the new config parser:
function                                             old     new   delta
config_read                                          393     386      -7
static.actions                                        72      64      -8
.rodata                                           121772  121764      -8
parse_inittab                                        554     393    -161
