CONFIG_PID_FILE_PATH: new configuration option for pidfile paths
We set a default path for the directory where pidfiles are create when FEATURE_PIDFILE is selected. The default has no effect on applets which must specify a pidfile path on the command line to run, and it can be overridden by applets which optionally allow the user to specify the pidfile path. We also add pidfile write/remove support for klogd, ntpd and watchdog. For syslogd, we add a missing remove_pidfile() for better cleanup on daemon exit. Signed-off-by: Anthony G.
