move package/linux into target/linux, use wbx' new kernel code. support building images with more than one kernel, split kernel module parts off of packages that use their own kernel modules (fuse, shfs, openswan). some cleanup in the image building process in target/. image builder is disabled for now, needs some fixing.

++ From here on USB initialization and deactivation related routines are implemented :
++
++ - hfc_usb_init :
++ is the main Entry Point for the USB Subsystem when the device get plugged
++ in. This function calls usb_register with usb_driver as parameter.
++ Here, further entry points for probing (hfc_usb_probe) and disconnecting
++ the device (hfc_usb_disconnect) are published, as the id_table
++
++ - hfc_usb_probe
++ this function is called by the usb subsystem, and steps through the alternate
++ settings of the currently plugged in device to detect all Endpoints needed to
++ run an ISDN TA.
++ Needed EndPoints are
++ 3 (+1) IntIn EndPoints (D-in, E-in, B1-in, B2-in, (E-in)) or
++ 3 (+1) Isochron In Endpoints (D-out, B1-out, B2-out) and 3 IsoOut Endpoints
++ The currently used transfer mode of on the Out-Endpoints will be stored in
++ hfc->usb_transfer_mode and is either USB_INT or USB_ISO
++ When a valid alternate setting could be found, the usb_init (see blow)
++ function is called
++
++ - usb_init
++ Here, the HFC_USB Chip itself gets initialized and the USB framework to send/receive
++ Data to/from the several EndPoints are initialized:
++ The E- and D-Channel Int-In chain gets started
++ The IsoChain for the Iso-Out traffic get started
++
++ - hfc_usb_disconnect
++ this function is called by the usb subsystem and has to free all resources
++ and stop all usb traffic to allow a proper hotplugging disconnect.
