Add a simple EFI stub loader. This is a quick and dirty of boot1.chrp from the PowerPC port with all the Open Firmware bits removed and replaced by their EFI counterparts. On the whole, I think I prefer Open Firmware. This code is supposed to be an immutable shim that sits on the EFI system partition, loads /boot/loader.efi from UFS and tells the real loader what disk/partition to look at. It finds the UFS root partition by the somewhat braindead approach of picking the first UFS partition it can find. Better approaches are called for, but this works for now. This shim loader will also be useful for secure boot in the future, which will require some rearchitecture.

Eliminate last vestigies of NO_MAN= in the tree. Also, remove ineffectual NOMAN= lines. These don't change the build at all.

Fix buildworld. I had some local bits in my build tree that caused this to work by accident.

Add generation of an EFI filesystem to hold boot1.efi. This is a near-exact copy of the code from boot1.chrp again. The resulting image is installed to /boot/boot1.efifat. If dd'ed to an 800K "efi" partition, it should result in a bootable system.

Apparently some of the i386 boot blocks are so close to full that adding single lines to ufsread.c spills them over. Duplicate a whole bunch of code to get file sizes into boot1.efi/boot1.c rather than modifying ufsread.c.
