small tool checking status of keyboard keys like shift, alt, control
placed in init sciprt, checking for hold lshift on keyboard, serves as a emergency
drop to init ram shell - without the need to remove SD card, change config files etc.
changes: variable names with dots - not posix - changed to _
(network.wlan0.mode -> network_wlan0_mode)
/etc/modules.wifiinit must hold wifi usb drivers, if wifi wants to be loaded early before rootfs
/etc/modules can by fully loaded only if udev is loaded with full scope of rules, this can happen
only after rootfs remount
root is now supported on any standard filesystem type, ext, btrfs, nfs was tested.
for nfsroot, no lock parameter must be added as mount options (i.e. nfsroot=ip:/volume,nolock)
added some udevd rules,
simplified busy box links creation
