description:
Cleanup and clarify the ELFSIZE mess:

We now have 2 variables automatically set in elf_machdep.h:

    ARCH_ELFSIZE: the size for userland binaries
    KERN_ELFSIZE: the size for the kernel binaries

DB_ELFSIZE has been deleted and KERN_ELFSIZE should have always the
same values DB_ELFSIZE used to have.

In sys/exec_elf.h, if ELFSIZE is not set, it is set to KERN_ELFSIZE
for the kernel and ARCH_ELFSIZE for userland. These defaults should
eliminate the need for most manual ELFSIZE setting.
