major cleanup and rewrite
- some functions have been renamed - some functions have changed prototype - no more bootloader::vga_modes, we use Xconfig::resolution_and_depth::bios_vga_modes() - no more detectloader, it is now detect_main_method(), but notice that bootloader::read() + bootloader::write() abstract all this! - update_for_renumbered_partitions() is surely broken :) - sort_hds_according_to_bios() and mixed_kind_of_disks() uses new function hd2bios_kind() - new data structure "kernel_str" - lilo doesn't need so much help as it used to be, so don't put as much "disk=/dev/sda bios=0x80" as before some goals: - don't rely on device names (this allows not to care too much about devfs vs udev vs ...) - kernels can be named something else than /boot/vmlinuz*, please use the various functions to construct the initrd file name, the symlink name...
