2adaa90534 ifplugd: if SIOCSIFFLAGS fails with EADDRNOTAVAIL, don't die 
When using ifplugd on a RNDIS interface with monitor mode, using
SIOCSIFFLAGS seems to fail with EADDRNOTAVAIL. Treat it the same
as if iface disappeared again.

This has been observed on a Tegra TK1 using Linux 4.14. There seem
to be a race when the kernel is creating the device:
  ifplugd(usb0): started: BusyBox v1.24.1 (2018-03-27 09:47:48 CEST)
  ifplugd(usb0): interface doesn't exist, waiting
  ifplugd(usb0): interface appeared
  ifplugd(usb0): upping interface
  ifplugd(usb0): setting interface flags failed: Cannot assign requested address
  <exit>

With this patch ifplugd is successful in upping the device the second
time around:

  ifplugd(usb0): upping interface
  ifplugd(usb0): using SIOCETHTOOL detection mode
  ifplugd(usb0): interface appeared
  ifplugd(usb0): upping interface
  ifplugd(usb0): setting interface flags failed: Cannot assign requested address
  ifplugd(usb0): interface appeared
  ifplugd(usb0): upping interface
  ifplugd(usb0): using SIOCETHTOOL detection mode
  ifplugd(usb0): link is up
  ifplugd(usb0): executing '/etc/ifplugd/ifplugd.usb.action usb0 up'
  ifplugd up
  ifplugd(usb0): exit code: 0

12677acf0a 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.
