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.
