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.
