Enable/disable SystemV init code at compile time
* configure.ac: New option --enable-sysvinit. Disable the init code if RUN_LVL is not available. (PIES_SYSVINIT_ENABLED): New configuration define. (PIES_COND_SYSVINIT): New condition Print configuration settings summary. * src/pies.h (is_sysvinit): Check for PIES_SYSVINIT_ENABLED. (SYSVINIT_ACTIVE): New macro. * grecs: Upgrade. * src/Makefile.am: Conditionally link sysvinit-related code. * src/cmdline.opt: Disable the --telinit option if sysvinit support is not available. (parse_options): Use SYSVINIT_ACTIVE in the conditional. * src/comp.c (component_verify): Check if component definition is allowed by the current state of the sysvinit support. * src/ctl.c: Disable the /runlevel entry point if sysvinit support is not compiled. * src/diag.c (stderr_open): Make sure sysvinit-related code is not compiled if the sysvinit support is not available. * src/pies.c (config_syntax_tab): Add entry for CONF_INITTAB only if sysvinit support is available. (_cb_initdefault,_cb_runlevels): Remove. Use cb_initdefault and cb_runlevels instead. (component_keywords): Disable runlevels without sysvinit support. (pies_keywords): Same for initdefault. Use SYSVINIT_ACTIVE to suppress compilation of sysvinit code without sysvinit support. * src/progman.c: Use SYSVINIT_ACTIVE to suppress compilation of sysvinit code without sysvinit support. * src/sysvinit.c (cb_initdefault,cb_runlevels): New functions.
