Log:
New FILO code drop from coresystems' internal repository:
* add "developer commands" to filo (lspci, setpci, io)
* use staged libpayload per default now.
* use libpayload-config.h where appropriate.
* fix an ext3 filesystem issues
* use libpayload functions to implement grub_printf instead of the incomplete
duplication
* fix broken "weak" symbol handling.
* fix string issue with boot_devices
* fix a couple of problems with colors
* fix endless loop in case of file open error
