Enable the i386 loader to load and run an amd64 kernel. If this puts

Most of the changes are to get the load_elf.c file into a seperate elf32_ or elf64_ namespace so that you can have two ELF loaders present at once. Note that for 64 bit kernels, it actually starts up the kernel already in 64 bit mode with paging enabled. This is really easy because we have a known minimum feature set. Of note is that for amd64, we have to pass in the bios int 15 0xe821 memory map because once in long mode, you absolutely cannot make VM86 calls. amd64 does not use 'struct bootinfo' at all. It is a pure loader metadata startup, just like sparc64 and powerpc. Much of the infrastructure to support this was adapted from sparc64.

Cut&Paste considered far too easy:

Move the remaining bits of to Move i386/pc98 specific bits from to as well. Adjust includes in sys/boot accordingly.

Consistently use NOFORTH to control the usage of ficl.

Link /boot/boot1 to the name /boot/boot to avoid per-arch naming of the

Renamed the loader's zipfs to gzipfs. zipfs.c was repo-copied to gzipfs.c.

Enable UFS2 support in boot1. Just as with sparc64 the same boot1 works
