Turn off the new /sys/boot stuff (except boot0) unless OBJFORMAT is elf. (The BTX client must be ELF, though it is packaged as a.out for compatibility.)

Add the new cdldr CD bootstrap loader. This patch includes the following: - Fix btxldr to preserve a NULL bootinfo pointer when it copies the kernel arguments. - Add the cdldr bootstrap program. This program is tacked onto the beginning of the standard 3rd stage boot loader (/boot/loader) to form the CD boot loader (/boot/cdboot). When a CD is booted, the cdboot file is copied into memory instead and executed. The cdldr stub emulates the environment normally provided by boot2 and then starts the loader. This booting method does not emulate a floppy drive, but boots directly off of the CD. This should fix the problems some BIOS's have with emulating a 2.88 MB floppy image. - Add support to the loader to recognize that it has been booted by cdldr instead of boot2 and use a simpler method of extracting the BIOS boot device.

This is the new unified bootstrap, sometimes known previously as the 'three-stage' bootstrap. There are a number of caveats with the code in its current state: - The i386 bootstrap only supports booting from a floppy. - The kernel and kld do not yet know how to deal with the extended information and module summary passed in. - PnP-based autodetection and demand loading of modules is not implemented. - i386 ELF kernel loading is not ready yet. - The i386 bootstrap is loaded via an ugly blockmap. On the alpha, both net- and disk-booting (SRM console machines only) is supported. No blockmaps are used by this code. Obtained from: Parts from the NetBSD/i386 standalone bootstrap.
