- Don't unconditionally set splash=silent
  * this conflicts with a possible value set in the kernelcmdline attribute
  * splash=silent impacts 'plymouth show-splash' in SLE12 not showing
    any splash which is not the desired behavior
- Fixed startPlymouth to reset the console after plymouth
  has messed with it using console_init provided by udev
- Fixed start of udevd
  * prefer systemd-udevd if it exists
  * provide only one function to actually start the daemon
  * set UDEV_LOG level to info
- Make sure pidof tool is part of the initrd. This tool is
  provided in sysvinit-tools thus had to fix the boot image
  descriptions for SLE12, openSUSE 13.2 and RHEL
- Make sure pidof command exists in preinit phase even if
  sysvinit-tools was not installed as part of the system
  image
- Fixed udevPending, make sure access to proc is granted
- v5.06.61 released
