Fix runlevel transition algorithm, implement SysV-style fifo interface.
* src/prog.h: New file. * src/Makefile.am: Add new file. * src/cmdline.opt: New option --telinit (-T). * src/diag.c (vlogmsg): In sysvin it mode, write directly to the console. Close it when finished. * src/pies.c (_cb_initdefault, _cb_runlevels): Use is_valid_runlevel to check if the specified runlevels are ok. (main): In sysvinit mode, reset action to ACTION_CONT. * src/pies.h (progman_filter): New proto. (progman_accept,register_socket): Change signature. (deregister_socket): New proto. (register_program_socket): New proto. * src/progman.c: Move constant and adatatype definitions to prog.h (prog_stop): Remove static qualifier. (console_open): Likewise. (progman_accept): Use new socket API. (progman_stop): Correctly handle timeouts. (progman_foreach): New function. * src/socket.c: Register all sockets along with their handlers in a doubly-linked list. (sockinst): New struct. (register_socket,deregister_socket): New functions. (register_program_socket): New function. (pies_pause): Traverse the list to find which fd has changed. Use its registered handler to handle the event. * src/sysvinit.c: Include prog.h (is_valid_runlevel): New function. (sysvinit_fifo_handler,check_fifo): New static functions. (inittrans): Fix transition algorithm. (telinit): New function.
